GREEN, J.W., Nuytsia 4 (3): 317–331 (1983)
Micromyrtus ciliata is redefined in consequence of the segregation from it of two new species, M. sessilis and M. striata. A third new species, M. blakelyi, belonging to the same group, is also described. All four species are mapped and illustrated. Micromyrtus minutiflora, based on mixed material, is lectotypified.
The genus Ondinea (Nymphaeaceae) including a new subspecies from the Kimberley region, Western Australia
KENNEALLY, K.F. AND SCHNEIDER, EDWARD L., Nuytsia 4 (3): 359–365 (1983)
A new subspecies, Ondinea purpurea Hartog subsp. petaloidea is described and illustrated. The occurrence of previously unreported petaloid flowers in the genus and the discovery of seedlings necessitates expanding the species description. The gradation from sepals to petals to petaloid stamens to conventional stamens provides additional morphological data to support the placement of Ondinea in the Nymphaeaceae sensu stricto.
A morphometric and anatomical study of the Darwinia diosmoides complex (Myrtaceae) in south-western Australia
RYE, B.L., Nuytsia 4 (3): 411–421 (1983)
Both floral morphology and leaf anatomy proved to be of little value in distinguishing the three variants of the Darwinia diosmoides complex. Morphometric analysis of foliar characters confirmed that the northern variant, which differs in chromosome number and several other respects, should be recognized as a new species (D. capitellata Rye). However, the two southern variants showed complete intergradation in their foliar characters; hence they were not considered sufficiently distinct to be given formal taxonomic rank.
Darwinia capitellata (Myrtaceae), a new species from south-western Australia
RYE, B.L., Nuytsia 4 (3): 423–426 (1983)
A new species, Darwinia capitellata Rye, is described. It differs from its closest relative, D. diosmoides (DC.) Benth., in bracteole shape and texture, distribution of oil glands, arrangement of flower heads, chromosome number and geographical distribution.

It comprises Eucalyptus rigens from north-west, north and north-east of Esperance, E. litorea from near Israelite Bay, both occurring around salt lakes, and E. famelica from east of Hopetoun, a species of subcoastal swamps. The series belongs in the informal Eucalyptus sect. Dumaria of Pryor & Johnson and is characterised by brown, somewhat flat to pyramidal seed, with the ventral side ribbed and dorsal side shallowly pitted.
New subspecies of Banksia seminuda and B. occidentalis (Proteaceae) from the south coast of Western Australia
HOPPER, STEPHEN D., Nuytsia 7 (1): 15–24 (1989)
Banksia seminuda subsp. remanens and B. occidentalis subsp. formosa are described and illustrated. Both have smaller leaves, are more floriferous and are smaller shrubs than their respective nominate subspecies. Both have outstanding horticultural merit. Their conservation in the wild will necessitate careful management, as both new subspecies may be killed by fire, and both have restricted geographical distributions. B. seminuda subsp. remanens and B. occidentalis subsp. formosa each have a distribution and morphological features suggesting that they are relictual taxa of Western Australian lineages that show the closest relationships to eastern Australian members of Banksia section Oncostylis.
Taxonomy of Olearia stuartii (Asteraceae : Astereae) and allied species
LANDER, N.S., Nuytsia 7 (1): 25–36 (1989)

The Australian species currently included in that genus and in the related genera Cephalipterum, Gilberta, Triptilodiscus and Pterochaeta are reclassified. One genus, Haptotrichion, is described as new. Under Rhodanthe 11 sections are recognised of which 1 is new and 10 are new combinations. Eight new species of Rhodanthe and one new species of Haptotrichion are described, these are R. ascendens, R. collina, R. cremea, R. gossypina, R. nullarborensis, R. psammophila, R. rufescens, R. sphaerocephala and H. colwillii. A number of new species combinations are made. Descriptions are given for each of the recognised genera and sections.
The classification of Australian species currently included in Helipterum and related genera (Asteraceae : Gnaphalieae) : Part 2 Leucochrysum
WILSON, PAUL G., Nuytsia 8 (3): 439–446 (1992)
A new endemic Australian genus, Leucochrysum (DC.) Paul G. Wilson, is described to accommodate Helipterum stipitatum, H. fitzgibbonii, and most of the taxa previously referred to the H. albicans group. New combinations are effected to accommodate the five species and five infraspecific taxa.
The classification of some Australian species currently included in Helipterum and Helichrysum (Asteraceae : Gnaphalieae) : Part 3 Anemocarpa and Argentipallium, two new genera from Australia
WILSON, PAUL G., Nuytsia 8 (3): 447–460 (1992)
Two new genera Anemocarpa and Argentipallium are described in the Gnaphalieae: Angianthinae. The first genus is based on a new species Anemocarpa calcicola from Western Australia and includes two other species: A. podolepidium [Helichrysum podolepidium F. Muell.], and A. saxatilis [Helipterum saxatile Paul G. Wilson]; it is apparently most closely related to the genera Leucochrysum (DC.) Paul G. Wilson and Chrysocephalum Walp. The second genus is based on Argentipallium obtusifolium (Sonder) Paul G. Wilson [Helichrysum obtusifolium Sonder] and includes five other species: A. blandowskianum [Helichrysum blandowskianum Sonder], A. dealbatum [Helichrysum dealbatum Labill.], A. niveum [Helipterum niveum Steetz], A. spiceri [Helichrysum spiceri F. Muell.], and A. tephrodes [Ozothamnus tephrodes Turcz.]; it is evidently most closely related to Ozothamnus R.Br.
The classification of the genus Waitzia Wendl. (Asteraceae : Gnaphalieae)
WILSON, PAUL G., Nuytsia 8 (3): 461–477 (1992)
The circumscription of Waitzia is discussed and a narrow generic concept proposed. Five species and two infraspecific taxa are recognised. A key is provided and full synonymy given. One new species combination, W. nitida, is made; two new varieties are described. Waitzia citrina, W. conica and W. paniculata are excluded from the genus.
A new species of Acomis from the Northern Territory and a new combination in the genus Thiseltonia (Asteraceae : Gnaphalieae)
WILSON, PAUL G., Nuytsia 8 (3): 479–483 (1992)
The recognition of the genera Rutidosis, Acomis, and Thiseltonia is discussed. A new species, Acomis kakadu, is described from Kakadu National Park, Northern Territory, and a new combination, Thiseltonia gracillima, is made for the plant previously known as T. dyeri.
New series, subseries, species and subspecies of Eucalyptus (Myrtaceae) from Western Australia and from South Australia
BROOKER, M.I.H. AND HOPPER, STEPHEN D., Nuytsia 9 (1): 1–68 (1993)
Three new series, six new subseries, twenty-two new species and twenty new subspecies of Eucalyptus are described. New taxa are treated in the order and nomenclature of the Flora of Australia Volume 19 (1988) from which we deviate only when we consider an updated treatment necessary. The new series Falcatae is erected and divided into two subseries, Falcatae and Decipientes. The series Micrantherae s.s. is expanded to include the new subseries Bakerianae, and a new series Balladonienses is erected. E. lane-poolei of series Curviptera is segregated in the new E. subseries Inflexae, E. caesia in the new E. series Caesiae, while E. series Orbifoliae comprises the remaining Minni Ritchi species. A new subseries Cupreanae is erected in E. series Lucasianae. Diagnostic notes on each taxonomic series are given at the head of the relevant groups of species throughout the paper. The new taxa are illustrated, except for E. ebbanoensis subsp. photina and E. marginata subsp. thalassica for which leaf colour and leaf gloss are the diagnostic characters, E. marginata subsp. elegantella and E. macrocarpa subsp. elachantha for which habit, bark characters and leaf, bud and fruit dimensions are the diagnostic characters and E. decipiens subspp. chalara and adesmophloia for which bark characters only are diagnostic. Distribution maps are provided. All the new taxa are endemic to Western Australia except for E. glomerosa and E. kingsmillii subsp. alatissima, both of which extend into the desert region of South Australia.
Acacia Miscellany 7. Acacia sulcata and related taxa (Leguminosae : Mimosoideae) in Western Australia
COWAN, R.S. AND MASLIN, B.R., Nuytsia 9 (1): 69–78 (1993)
A key is presented to the nine taxa of the informal “A. sulcata group”, followed by a review of A. sulcata R. Br., including the description of a new variety A. sulcata var. planoconvexa Cowan & Maslin; in addition, a new variety of A. brachyphylla Benth. is described (var. recurvata Cowan & Maslin) and a new species, A. octonervia Cowan & Maslin. In addition, A. nitidula Benth. and A. sulcata var. platyphylla have been lectotypified.
Acacia Miscellany 8. Acacia masliniana (Leguminosae : Mimosoideae : section Plurinerves), a new species of Western Australia
COWAN, R.S., Nuytsia 9 (1): 79–82 (1993)
Acacia masliniana is described and compared with related taxa in the context of a discussion of their morphological character states.
Acacia Miscellany 9. The taxonomic status of Acacia coriacea (Leguminosae : Mimosoideae : section Plurinerves)
COWAN, R.S. AND MASLIN, B.R., Nuytsia 9 (1): 83–90 (1993)
Acacia coriacea DC. is regarded as comprising three subspecies, subsp. coriacea (which is here lectotypified), subsp. pendens Cowan & Maslin, subsp. nov. and subsp. sericophylla (F. Muell.) Cowan & Maslin, comb. et stat. nov. These are described and compared with the similar appearing A. stenophylla; a key is provided to distinguish the four taxa.
A new species of Restionaceae from south-western Australia
DIXON, K.W., MENEY, K.A. AND PATE, J.S., Nuytsia 9 (1): 91–94 (1993)
Restio isomorphus is a new species of Australian Restionaceae from a restricted area in the south-west of Western Australia. Rhizome morphology and ecological factors likely to influence the conservation status of this species are discussed.
Drummondita wilsonii, Philotheca langei and P. basistyla (Rutaceae), new species from south-west Western Australia
MOLLEMANS, F.H., Nuytsia 9 (1): 95–109 (1993)
One new species of Drummondita and two new species of Philotheca are described. All three taxa are apparently rare, each restricted to limited geographic areas. _Drummondita wilsonii_is similar to D. ericoides, but has unequal calyx segments in common with D. miniata. Philotheca langei and P. basistyla both have affinities with Eriostemon falcatus which is currently presumed extinct. Similarities between D. wilsonii, D. ericoides and D. miniata, pollination mechanisms and flower colour variation in Drummondita, distribution and flowering time of the D. ericoides group (which includes D. miniata and D. wilsonii) and the evolutionary history of the Drummondita ericoides group, D. hassellii group and D. calida are discussed.
The status, ecology and relationships of Meziella (Haloragaceae)
ORCHARD, A.E. AND KEIGHERY, G.J., Nuytsia 9 (1): 111–117 (1993)
The monotypic genus Meziella has until now been known only from its very fragmentary and immature type. Because of this its status as a genus and relationships have been unclear, and its description has been incomplete. Recent rediscovery of the species has allowed a full description to be prepared for the first time. It is now confirmed that Meziella is a distinct genus, intermediate in many respects between Haloragis and Myriophyllum. Its somewhat bizarre features are described, its ecology discussed, and a revised key to the Australian genera of the family is provided.
Thomasia glabripetala (Sterculiaceae), a new species from south-west Western Australia
PATRICK, S.J., Nuytsia 9 (1): 119–122 (1993)
A new species of Thomasia (Sterculiaceae) is described and illustrated, namely Thomasia glabripetala S.J. Patrick, endemic to the Avon Botanical District of the South-West Botanical Province of Western Australia. This is a declared rare species which, until recently, has been confused with Thomasia montana Steudel.
Croninia kingiana (Epacridaceae), a change in status for Leucopogon kingianus
POWELL, J.M., Nuytsia 9 (1): 123–130 (1993)
Leucopogon kingianus, an endemic Western Australian species exhibiting features atypical of Leucopogon is transferred to the new monotypic genus Croninia J. Powell as C. kingiana (F. Muell.) J. Powell.
Cytological notes in Rutaceae. 1 Boronia tenuis
STACE, HELEN M. AND PATRICK, S.J., Nuytsia 9 (1): 131–133 (1993)
A new chromosome number determination for Boronia tenuis (n=16) corrects a prior report and has implications for the cytotaxonomy of Boronia in Western Australia.
A revision of the genus Eremaea (Myrtaceae)
HNATIUK, ROGER, J., Nuytsia 9 (2): 137–222 (1993)
Eremaea is a genus of shrubs and small trees endemic in south-western Australia. It has an unusual distribution in that 15 of its 16 species occur on or very close to the coastal plain (Irwin and Darling Botanical Districts) and one species extends throughout much of the non-forested areas of the South West Botanical Province. The genus is a significant component of the shrub layer of several vegetation types. Eight new species, 5 subspecies, and 8 varieties are described (E. asterocarpa subsp. asterocarpa, E. asterocarpa subsp. histoclada, E. asterocarpa subsp. brachyclada, E. atala, E. hadra, E. beaufortioides var. beaufortioides, E. beaufortioides var. lachnosanthe, E. beaufortioides var. microphylla, E. blackwelliana, E. ebracteata var. ebracteata, E. ebracteata var. brachyphylla, E. x codonocarpa, E. dendroidea, E. ectadioclada, E. pauciflora var. pauciflora, E. pauciflora var. calyptra, E. pauciflora var. lonchophylla, E. x phoenicea, E. violacea subsp. violacea and E. violacea subsp. raphiophylla). Keys to and descriptions of taxa, and illustrations of most taxa are presented. An index to taxa is given on page 222.
Nemcia effusa (Fabaceae : Mirbelieae), a new species from south-west Western Australia, and a key to Nemcia
CRISP, M.D. AND MOLLEMANS, F.H., Nuytsia 9 (2): 223–232 (1993)
A new species of Nemcia, N. effusa Crisp & Mollemans, is described from the north-west part of Lake Grace shire, south-west Western Australia. The species is quite distinct with no clear affinities. It is named for its habit with rigid, diffuse stems and branchlets. In some respects similar to N. stipularis (Meissner) Crisp, it differs in the leaves spreading widely and being broader(3-4 mm) and impressed-punctate below, and with stipules shorter (2-3 mm). It is also similar to N. punctata (Turcz.) Crisp in the leaves being impressed-punctate below, but differing in having conspicuous stipules and longer leaves (1-2.5 cm) that are spreading widely but scarcely recurved. Only two plants of N. effusa were found at the type locality, and the species was not observed elsewhere during surveys of remnant vegetation (by the second author) of c. 71,250 km² of the southern wheatbelt region of Western Australia. This suggests that N. effusa is neither widespread nor common.
Wurmbea calcicola (Colchicaceae), a new species from Cape Naturaliste, south western Australia
MACFARLANE, T.D., Nuytsia 9 (2): 233–236 (1993)

Eight new species and 8 new subspecies are described; 3 currently accepted subspecies are raised to specific rank; 1 species currently in synonymy is reinstated at specific rank. Keys are provided to enable separation from closely related species. An index to taxa is given on page 304.
Eucalyptus series Brevifoliae (Myrtaceae), a new series of northern Australian eucalypts
BROOKER, M.I.H. AND SLEE, A.V., Nuytsia 9 (3): 307–314 (1994)
A new infrageneric taxon, Eucalyptus series Brevifoliae is described. The group consists of six species of northern Australian white gums, viz. E. confluens, E. rupestris and E. ordiana, endemic to the Kimberley in Western Australia, E. brevifolia, from the Kimberley and adjacent parts of the Northern Territory, E. umbrawarrensis endemic to the Top End of the Northern Territory, and E. leucophloia which occurs from the Pilbara across the Northern Territory to western Queensland. The series is diagnosed by seed and leaf characters.
Mueller’s ‘The plants indigenous to the colony Victoria’ – Is volume 2 effectively published?
COURT, A.B., COWAN, R.S. AND MASLIN, B.R., Nuytsia 9 (3): 315–318 (1994)
Historical notes are provided to support the conclusion that the second volume of this work was not effectively published and the new names it included are therefore invalid. A summary is appended that will be of assistance to librarians and bibliographers in understanding the chronology and content of the several publications concerned.
Three new species, a new name and notes on Australian Polycarpaea (Caryophyllaceae)
COWIE, I.D., Nuytsia 9 (3): 319–332 (1994)
Polycarpaea incana, P. microceps and P. tenax are described and illustrated and a new name, P. multicaulis, is chosen for the later homonym P. microphylla Pedley. Variation in these taxa, as well as P. breviflora, P. corymbosa, P. involucrata, P. spirostylis and P. violacea is discussed. A key to Australian species is included.
New taxa of Verticordia (Myrtaceae : Chamelaucieae) from Western Australia
GEORGE, E.A. AND GEORGE, A.S., Nuytsia 9 (3): 333–341 (1994)
Four recently discovered new taxa are described and discussed: Verticordia aereiflora, V. apecta, V. x eurardyensis (a presumed hybrid between V. dichroma and V. spicata) and V. luteola var. rosea.
Stylidium costulatum (Stylidaceae), a new tropical species of triggerplant from the Kimberley, Western Australia and the lectotypification of S. floodii
KENNEALLY, K.F. AND LOWRIE, A., Nuytsia 9 (3): 343–349 (1994)
A new species of Stylidium (Stylidiaceae) from the Kimberley Region, S. costulatum Lowrie and Kenneally is described and illustrated and S. floodii, its closest relative, is lectotypified. The terms cunabulum (for the dilated part of the column) and torosus (for the mobile column hinge) are proposed.
Notes and new species of Acacia (Mimosaceae) from northern Australia
LEACH, G.J., Nuytsia 9 (3): 351–362 (1994)
Acacia tolmerensis G. Leach is described as a new species in the informal A. platycarpa group (Sect. Plurinerves). The informal A. plectocarpa group (Sect. Juliflorae) is defined as including A. plectocarpa Cunn. ex Benth. subsp. plectocarpa, A. plectocarpa subsp. tanumbirinensis (Maiden) Pedley, A. armitii F. Muell. ex Maiden and a new species, A. echinuliflora G. Leach. Relationships within the group are discussed, descriptions and a key to all taxa in the group are provided. Distribution maps for all taxa are presented.
Drosera ordensis (Droseraceae), a new tropical species of carnivorous plant from northern Australia
LOWRIE, A., Nuytsia 9 (3): 363–367 (1994)
A new species, Drosera ordensis (Droseraceae) is described from tropical northern Australia. The features that distinguish this taxon from its nearest relatives are presented and an indication is given of its habitat preferences.
Stylidium pulviniforme (Stylidiaceae), a new species of triggerplant from south-west Western Australia
LOWRIE, A. AND KENNEALLY, K.F., Nuytsia 9 (3): 369–373 (1994)
A new species of Stylidium (Stylidiaceae) endemic to south-west Western Australia, S. pulviniforme Lowrie and Kenneally, is described and illustrated.
Chamaexeros longicaulis (Dasypogonaceae), a new species from Walpole, south western Australia, with additional notes on Chamaexeros
MACFARLANE, T.D., Nuytsia 9 (3): 375–382 (1994)
The new species is described and illustrated with photographs. Chamaexeros longicaulis is most closely related to C. serra but differs in several characteristics including three unique in the genus: elongated stems, elongated rhizomes resulting in vegetative reproduction, and thickened vertical rhizomes which presumably provide for storage of reserves. The species is of conservation interest owing to the small number of populations known, and is listed among conservation priority taxa for Western Australia. A revised key to the species of Chamaexeros is presented. Features of the ovary, capsule and seed are clarified for this genus. Floral measurement data are given for all species. A range extension is noted for C. serra.
William Vincent Fitzgerald’s species of Acacia (Leguminosae : Mimosoideae) : typification of names
MASLIN, B.R. AND COWAN, R.S., Nuytsia 9 (3): 387–398 (1994)
William Vincent Fitzgerald described 33 new species of Acacia in four papers published between 1904 and 1917. Notes on these publications and on the specimens used by Fitzgerald are provided. Lectotypes are selected for 23 names, based on specimens located at BM (4), PERTH (6) and NSW (13).
C.F. Meissner’s species of Acacia (Leguminosae : Mimosoideae) : typification of names
MASLIN, B.R. AND COWAN, R.S., Nuytsia 9 (3): 399–414 (1994)
The type status of names for all 56 taxa described by Meissner in Lehmann’s "Plantae Preissianae" (1844 and 1848) and in a subsequent paper in "Botanisches Zeitung" (1855) has been carefully assessed. Consequently, we have fixed the application of these names by choosing lectotypes wherever possible from among the syntypes, particularly those at BM, LD and NY. Of the lectotypes selected here 19 are at LD, 10 are at NY and 2 at BM.
A new species of Nicotiana (Solanaceae) from near Broome, Western Australia
SYMON, D.E. AND KENNEALLY, K.F., Nuytsia 9 (3): 421–425 (1994)
Nicotiana heterantha Symon & Kenneally is described from near Broome, Western Australia. The new species is known from only two populations, both of which are under threat from grazing. It appears most closely related to N. rosulata subsp. rosulata.

Acacia Miscellany 11. Miscellaneous taxa of northern and eastern Australia of Acacia section Plurinerves (Leguminosae : Mimosoideae)
COWAN, R.S. AND MASLIN, B.R., Nuytsia 10 (1): 63–84 (1995)
Two new species (A. kenneallyi Cowan & Maslin and A. manipularis Cowan & Maslin) and one new subspecies (A. retivenea F. Muell. subsp. clandestina Cowan & Maslin) are described. Acacia lanigera Cunn. is distinguished from A. venulosa Benth. and is viewed as comprising three varieties, var. lanigera, var. gracilipes Benth. and var. whanii (F. Muell. ex Benth.) Pescott (syn. A. whanii F. Muell. ex Benth.). In addition, lectotypes for several taxa are designated herein: A. subporosa var. linearis Benth. (the base name for A. cognata Domin), A. excelsa Benth., A. hemignosta F. Muell., A. lanigera Cunn., A. lanigera var. gracilipes Benth., A. leucophylla Lindley (= A. pendula Cunn. ex Don), A. praelongata F. Muell., A. subporosa F. Muell., and A. trinervata var. brevifolia. A note concerning the binomial A. sericata Cunn. ex Benth. is also included and discussions are presented concerning A. farinosa Lindley, A. latescens Benth. and A. trinervata Sieber ex DC.
Acacia Miscellany 12. Acacia myrtifolia (Leguminosae : Mimosoideae : section Phyllodineae) and its allies in Western Australia
MASLIN, B.R., Nuytsia 10 (1): 85–101 (1995)
Five new species and one new subspecies of Acacia from Western Australia are described, namely, A. clydonophora Maslin, A. disticha Maslin, A. durabilis Maslin, A. heterochroa Maslin (comprising subsp. heterochroa and subsp. robertii Maslin) and A. pygmaea Maslin. These taxa, together with four previously described species, A. celastrifolia Benth., A. myrtifolia, A. nervosa DC. and A. obovata Benth. comprise the informal "Acacia myrtifolia Group". A key to the species of this Group is presented. Brief notes on the variation in the Western Australian populations of A. myrtifolia are given. Acacia pawlikowskyana Ohlend. is treated as a synonym of A. myrtifolia (this name was formerly treated as a synonym of A. celastrifolia). Acacia acutifolia Maiden & Blakely is also regarded as conspecific with A. myrtifolia; it is likely that the type information published by Maiden and Blakely for this name was erroneous.
Alyxia tetanifolia (Apocynaceae), a new species from south west Australia
CRANFIELD, R.J., Nuytsia 10 (1): 103–105 (1995)
A new species endemic to the Austin Botanical district of the Eremaean Botanical Province of Western Australia, namely A. tetanifolia, is described, illustrated and mapped. A key to Western Australian species of Alyxia is provided.
Robert Brown, the typification of his new Acacia names in edition 2 of Aiton’s ‘Hortus kewensis’
MASLIN, B.R. AND COWAN, R.S., Nuytsia 10 (1): 107–118 (1995)
Robert Brown published nine new species of Acacia in W.T. Aiton’s second edition of "Hortus Kewensis". In the past, typification of these species has presented problems for two main reasons. Firstly, there were uncertainties regarding the material on which they were based, i.e. Brown’s "wild" gatherings from Australia between 1801 and 1805, and/or from plants in cultivation in England. Secondly, it appears that there are no cultivated specimens extant which can be regarded as type material. There is, however, a collection by William McNab, a gardener at Kew, who made specimens of Brown’s Acacia species from cultivated plants at Kew between 1806 and 1809; this collection is curated by the National Herbarium at Dublin (DBN). The following Brown species names are here lectotypified on the basis of Brown’s "wild" material: A. alata, A. biflora, A. marginata (=A. myrtifolia), A. melanoxylon, A. pulchella and A. sulcata; a neotype for A. acicularis (=A. brownii) has been chosen from Brown’s "wild" collections while A. armata is neotypified on a cultivated plant in the William McNab collection at DBN. One species, A. ciliata (= A. browniana var.browniana), had been neotypified in a previous paper.
New and priority taxa in the genera Spyridium and Trymalium (Rhamnaceae) of Western Australia
RYE, B.L., Nuytsia 10 (1): 119–140 (1995)
The following new Rhamnaceae taxa are described and illustrated: Spyridium glaucum Rye, S. minutum Rye, S. montanum Rye, S. mucronatum Rye, S. mucronatum subsp. multiflorum Rye, S. mucronatum subsp. recurvum Rye, S. riparium Rye, Trymalium densiflorum Rye, T. elachophyllum Rye, T. floribundum subsp. trifidum Rye, T. ledifolium var. lineare Rye and T. venustum Rye. Half of these taxa are presently included on the Priority Flora List. Other species of Spyridium and Trymalium on this conservation priority list are also illustrated and two new combinations are made, namely Spyridium majoranifolium (Fenzl) Rye and Spyridium polycephalum (Turcz.) Rye.
Two new species of Tetratheca (Tremandraceae), from the Coolgardie and Austin Botanical Districs, Western Australia
ALFORD, JENIFER J., Nuytsia 10 (2): 143–149 (1995)
Two new species of Tetratheca (Tremandraceae), T. chapmanii, endemic to the Carnarvon Range in the Austin Botanical District, Eremaean Province and T. paynterae, endemic to one small range of hills north of Bullfinch in the Coolgardie Botanical District, South-Western Interzone, are described and illustrated. A key and a table of differences are provided to facilitate recognition of the two newly described species and the morphologically-similar species T. aphylla and T. halmaturina.
Acacia Miscellany 13. Taxonomy of some Western Australian phyllocladinous and aphyllodinous taxa (Leguminosae : Mimosoideae)
MASLIN, B.R., Nuytsia 10 (2): 151–179 (1995)
Descriptions are provided for eleven endemic Western Australian species of Acacia characterized by phyllodes which are either decurrent on the stems and forming prominent opposite wings, or which are reduced to scales or minute, horn-like projections. Seven new species and two new infraspecific taxa of Acacia are described, namely, A. aemula Maslin which comprises two subspecies, subsp. aemula and subsp. muricata Maslin (syn. A. tetragonocarpa var. scabra Benth.), A. alata var. tetrantha Maslin, A. applanata Maslin, A. bifaria Maslin, A. carens Maslin, A. cerastes Maslin, A. cummingiana Maslin and A. pterocaulon Maslin. The taxonomy of A. alata R. Br. Is briefly assessed and the species is now viewed as comprising four varieties, namely, var. alata, var. biglandulosa Benth., var. platyptera (Lindl.) Meisn. and var. tetrantha Maslin. A description is provided for A. volubilis F. Muell.; this species is possibly extinct and seems related to A. aemula. Acacia glaucoptera Benth., a close relative of A. bifaria, and A. willdenowiana H. Wendl. (based on A. diptera Lindl.), a closerelative of A. applanata, are lectotypified.

James Drummond’s newspaper accounts of his collecting activities, in particular his 4th Collection and Hakea victoria (Proteaceae)
BARKER, R.M., Nuytsia 11 (1): 1–9 (1996)
At least three plants, Hakea victoria, Gastrolobium leakeanum and Verticordia grandis, all recognized and published by James Drummond, were first published in Perth newspapers, not in journals edited by William Hooker as has been assumed. This is possibly so for other plants attributed to Drummond in Hooker’s journals. The full newspaper account of the expedition on which Drummond made his 4th Collection is reproduced here since Hooker only communicated an abridged version of Drummond’s original letter.

MACFARLANE, T.D. AND WARDELL-JOHNSON, G., Nuytsia 11 (1): 71–78 (1996)
The rare new locally endemic species Anthocercis sylvicola T.D. Macfarlane & Wardell-Johnson is described and illustrated photographically. Anthocercis sylvicola is most closely related to A. genistoides Miers and A. anisantha Endl., but differing most obviously in the smaller green and purple flowers. It is the only member of the genus confined to tall open-forest. Although restricted, its distribution shows a marked discontinuity, a common situation for conservative, relictual high-rainfall taxa in the area. The species is of conservation interest owing to the small area of distribution and small number of plants and populations known. It is listed among conservation priority taxa for Western Australia. A revised key to the spinescent species of Anthocercis is presented.

In 1992 the author collected (voucher Keighery 11030) an unknown vigorous twining annual vine superficially similar to Fumaria capreolata L. (Fumariaceae), but with yellow flowers and spiny fruits (Figure 1). The plants were growing in Banksia woodland below Reabold Hill in Bold Regional Park, 8 km west of Perth. It was subsequently identified as Succowia balearica (L.) Medicus, a native of the western Mediterranean.
Lambertia rariflora subsp. lutea (Proteaceae): revised geographical distribution and habitat notes
MACFARLANE, T.D., HEARN, R.W. AND ANNELS, A.R., Nuytsia 11 (1): 141–143 (1996)
Lambertia rariflora subsp. lutea Hnatiuk is a recently described tall shrub or small tree from the Walpole Region, south western Australia (Hnatiuk 1995). At the time of its original description the taxon was known from only two collections, habitat details were few, and information on abundance and geographical distribution inadequate. Consequently it has been considered to be possibly rare. As part of our work on a Recovery Plan for the rare, endangered and conservation priority flora of the Department of Conservation and Land Management‘s Southern Forest Region (Hearn et al. in prep.), we undertook a field survey of L. rariflora subsp. lutea . The results are reported here ahead of the Recovery Plan in order to improve the available published information on the species as soon as possible.

It has become established along the southern coast of mainland Australia from Western Australia to Victoria and north-east Tasmania (Hnatiuk 1990).
The Rhamnaceae of the Kimberley Region of Western Australia
RYE, B.L., Nuytsia 11 (2): 287–292 (1997)
Six native species of Rhamnaceae, all in different genera, are known from the Northern Botanical Province of Western Australia. This province is equivalent to the Kimberley Region as defined in "Flora of the Kimberley Region", in which five of the Rhamnaceae species are described and illustrated (Wheeler 1992). Since publication of the Kimberley flora, a further species and genus, Colubrina asiatica, has been discovered at Koolama Bay in the far north of the Kimberley, and there has been an alteration of the specific name used for the Alphitonia species in the region. In addition, unpublished work on generic boundaries in the Rhamnaceae suggests that the species currently known as Cryptandra intratropica should be placed in a new genus (K. Thiele pers. comm.).

LEPSCHI, B.J. AND MACFARLANE, T.D., Nuytsia 11 (3): 425–427 (1997)
Digitaria Haller is a cosmopolitan genus represented in Western Australia by 15 indigenous and four introduced species. In early 1996, the first author collected a weedy Digitaria (Lepschi & Lally 2486) on the northern outskirts of Perth which did not match any Digitaria species so far recorded from Western Australia. Subsequent examination of the collection by the second author revealed the plant to be D. aequiglumis (Hackel & Arechav.) Parodi, a South American species sparingly naturalized in eastern and southern Australia (Webster 1984).

A new species of Typhonium (Araceae: Areae) from the West Kimberley, Western Australia
HAY, A., BARRETT, M.D. AND BARRETT, R.L., Nuytsia 13 (1): 243–245 (1999)
Typhonium Schott is a genus of about 40 species of East Asian and Australian geophytic, mostly saproentomophilous aroids, the largest genus of the eastern-hemispheric tribe Areae. Typhonium has been revised recently for Australia (Hay 1993) and in toto (Sriboonma 1994), with the subsequent addition of three new species in Australia (Hay 1996; Hay & Taylor 1997). Several further new species are also coming to light in Indochina (Dzu & Croat 1997; Hetterscheid, pers. comm.). Here we describe another new Australian species, bringing the total for Australia to 17, of which all but two are endemic. A key to Australian Typhonium, including this new species, will appear in the forthcoming treatment for “Flora of Australia” (Hay, in prep.).

WILKINS, C.F. AND CHAPPILL, J.A., Nuytsia 13 (3): 571–594 (2001)
A taxonomic revision of Lysiosepalum F. Muell., a genus endemic to south-western Australia, identified five species. These comprise two currently accepted species L. involucratum (Turcz.) Druce and L. rugosum Benth., the reinstated L. hexandrum (S. Moore) S. Moore and two new species L. abollatum C.F. Wilkins (CALM Priority One) and L. aromaticum C.F. Wilkins (CALM Priority Two) that probably require recognition as Declared Rare Flora. A cladogram based on morphological data indicates that Lysiosepalum is a monophyletic genus, strongly supported by three synapomorphies unique in tribe Lasiopetaleae: calyx tube very short (lobes scarcely fused at the base); calyx lobes of alternating broad and narrow widths; epicalyx bracts equally spaced to completely enclose the mature bud. A chromosome number of n = 10 for L. involucratum is the first published record for the genus.

Two new species of silver mallet (Eucalyptus - Myrtaceae) of very restricted distribution in south-western Western Australia
NICOLLE, D., Nuytsia 15 (1): 77–83 (2002)
Eucalyptus rugulata Nicolle sp. nov. is described from the South Ironcap-Hatter Hill area north-east of Lake King, distinguished within the silver mallets by its broad and thick adult leaves and the large and robust buds and fruits. E. purpurata Nicolle sp. nov. is described from a single population near Bandalup Hill east of Ravensthorpe. It is distinguished from E. argyphea L.A.S. Johnson & K.D. Hill by the conspicuous red-purple new growth and the smaller buds and fruits. Both new species are of restricted distribution and E. purpurata, in particular, is considered to be at risk. A key and distribution map for the silver mallets are presented.

(Proteaceae: Grevilleoideae) are described. Their affinities are discussed and keys are provided. All of the new species have conservation priority.
A revision of the south-western Australian species of Micromyrtus (Myrtaceae) with five antisepalous ribs on the hypanthium
RYE, B.L., Nuytsia 15 (1): 101–122 (2002)
Among the species currently included in Micromyrtus Benth., two main categories are distinguished here on the basis of hypanthium ribbing, one characterised by having antipetalous ribs and usually also antisepalous ones, the other by having antisepalous ribs but no antipetalous ones. Most species belong to the latter category, including the lectotype selected here for the genus, Micromyrtus drummondii Benth. nom. superfl. [= M. obovata (Turcz.) J.W. Green]. A key is given to the 14 Western Australian members of this group, and the eight south-western species, including five new species, are revised. Micromyrtus erichsenii Hemsl. is reinstated and the new species M. monotaxis Rye, M. ninghanensis Rye, M. papillosa J.W. Green ex Rye, M. rogeri J.W. Green ex Rye and M. uniovula Rye are illustrated. Three of these new species have an ovule number of one, lower than any previously recorded for the genus, and four of them have conservation priority.
Scaevola ballajupensis (Goodeniaceae), a new species from the Jarrah forest of south-western Australia
SAGE, L.W., Nuytsia 15 (1): 123–126 (2002)
The new species Scaevola ballajupensis L.W. Sage, from the south-western Australian Jarrah forest, is described and photographically illustrated. The species is known only from one locality on private property and therefore has a high conservation priority. An amendment to the key to Scaevola species in "Flora of Australia" is made to include the new taxon and a table showing how it differs from its closest relatives is provided.
A revision of Hibbertia depressa and its allies (Dilleniaceae) from Western Australia
WHEELER, J.R., Nuytsia 15 (1): 127–138 (2002)

Wheeler and H. stenophylla J.R. Wheeler are described, mapped and illustrated. All belong to either section Pleurandra (Labill.) Benth. or section Hemipleurandra Benth. They are recorded from the Avon Wheatbelt, Jarrah Forest and Mallee regions of the South West Botanical Province and the Coolgardie, Murchison and Yalgoo regions of the Eremaean Province.
Lectotypification of two Western Australian species of Micromyrtus (Myrtaceae)
RYE, B.L., Nuytsia 15 (1): 153–154 (2002)
Among the species of Micromyrtus Benth. (Myrtaceae) that Bentham (1867) described in "Flora Australiensis", were two Western Australian species that had previously been recognised as distinct taxa by Ferdinand von Mueller. One had been described as Thryptomene elobata (Mueller 1864) and another had been given the manuscript name T. racemosa F. Muell. The purpose of this short communication is to select a lectotype from among the syntypes of each of these species.
Eucalyptus conglobata subsp. perata (Myrtaceae), a new taxon from southern Western Australia and notes on E. series Rufispermae

Eucalyptus virginea and E. relicta (Myrtaceae), two new rare forest trees from south-western Australia allied to E. lane-poolei, and a new phantom hybrid
HOPPER, STEPHEN D. AND WARDELL-JOHNSON, G., Nuytsia 15 (2): 227–240 (2004)
Eucalyptus virginea and E. relicta are described from Mt Lindesay National Park and from the Whicher Range south-east of Busselton respectively. Both species, together with E. lane-poolei, are in the earliest branching clade of E. ser. Curviptera, which contains many horticulturally attractive large-flowered mallees from semi-arid and desert regions such as E. macrocarpa and E. youngiana. The discovery and description of these two rare relictual forest trees so recently highlights the need for ongoing botanical survey of south-western Australia’s forests. A phantom hybrid, Eucalyptus lane-poolei × relicta, is also described for the first time. It occurs close to populations of E. relicta in the Whicher Range but 150 km south of the nearest recorded E. lane-poolei.

Recognition of Eucalyptus quaerenda at specific rank
BYRNE, M., Nuytsia 15 (2): 321–323 (2004)
Phylogenetic analysis of the relationships between the taxa in the Eucalyptus angustissima complex have been investigated using RFLP analysis of nuclear genome (Elliott and Byrne 2003) (Voucher specimens at PERTH: W. O’Sullivan 127, 357, 812, 968, 966, 1183, 1190, 1193, 1194). This study assessed populations of E. angustissima subsp. angustissima, E. angustissima subsp. quaerenda, E. foliosa and E. misella and found all four taxa to be genetically distinct. Eucalyptus angustissima was not monophyletic as the two subspecies did not cluster together. Eucalyptus misella was sister species to E. angustissima subsp. angustissima, and E. foliosa was sister species to both these taxa. Eucalyptus angustissima subsp. quaerenda was the most distinct of the four taxa.
Correction of type locality and flowering time for Melaleuca apostiba (Myrtaceae)
LEWINGTON, M.A., Nuytsia 15 (2): 324–324 (2004)
Melaleuca apostiba K.J. Cowley was described from a specimen collected by R. Morland during a Lands & Surveys Department expedition to the Officer Basin in 1963. The holotype of M. apostiba has the collecting number M10, with the label recording the locality as ‘between Carnegie and Giles’ and the collection date as June 1963.
A first report of Leptochloa panicea subsp. brachiata (Poaceae) from Western Australia
SNOW, NEIL, Nuytsia 15 (2): 325–326 (2004)
The genus Leptochloa P. Beauv. (Poaceae) is represented by nine species in Australia (Sharp and Simon 2002). Three of these include subspecies, bringing the total number of taxa in Australia to fourteen. I report here the first confirmed occurrence in Western Australia of Leptochloa panicea (Retz.) Ohwi subsp. brachiata (Steud.) N. Snow, a non-native taxon of neotropical origin.
Nomenclatural notes on two species of Hibbertia (Dilleniaceae)
WHEELER, J.R., Nuytsia 15 (2): 327–328 (2004)
Examination of type material of Hibbertia rhadinopoda and closely related taxa has revealed that there is an earlier name for H. rhadinopoda in the genus Pleurandra Labill. The necessary new combination is made here. A lectotype is also chosen for Hibbertia inclusa.
Two new species of Brachyloma (Epacridaceae) from the South West Botanical Province of Western Australia
CRANFIELD, R.J., Nuytsia 15 (3): 331–336 (2005)

Reinstatement of Burchardia congesta (Colchicaceae)
KEIGHERY, G.J. AND MUIR, W., Nuytsia 15 (3): 347–354 (2005)
Burchardia R. Br. is an endemic Australian genus of five species in the Colchicaceae. Burchardia umbellata R. Br. is a widespread taxon occurring disjunctly in temperate Eastern Australia and in south-west Western Australia. Studies on the morphology, ecology and anatomy of the Western and Eastern populations have shown marked discontinuities in character sets, leading to the recognition that each area is a seperate taxon. The name B. congesta Lindl. is re-instated for the Western populations and the name B. umbellata restricted to the Eastern populations.
A taxonomic revision of Drosera section Stolonifera (Droseraceae) from south-west Western Australia
LOWRIE, A., Nuytsia 15 (3): 355–394 (2005)
Ten species are recognized in the Drosera section Stolonifera: D. fimbriata DeBuhr, D. humilis Planchon, D. platypoda Turcz., D. porrecta Lehm., D. purpurascens Schlott., D. ramellosa Lehm., and D. stolonifera Endl., including three new combinations: D. monticola (Lowrie & Marchant) Lowrie, D. prostrata (Marchant & Lowrie) Lowrie and D. rupicola (Marchant) Lowrie. All are endemic to the south-west of Western Australia and belong in Drosera L. subgen. Ergaleium DC. sect. Stolonifera DeBuhr. Each taxon is described in detail as well as illustrated. A key is provided to all taxa in sect. Stolonifera. A schematic illustration of all ten species life-form is provided for comparison and cross referencing with each other. SEM micrographs of the seeds of each species, field and cultivation studies and historical investigations are also presented.
A rare and endangered new subspecies of Eucalyptus sargentii (Myrtaceae) with high potential for revegetation of saline sites from south-western Australia and notes on E. diminuta and E. sargentii subsp. fallens
NICOLLE, D., Nuytsia 15 (3): 395–402 (2005)
Eucalyptus sargentii subsp. onesia Nicolle subsp. nov. is described. It is known from less than ten small populations in the central wheatbelt of southwest Western Australia, with all populations occurring on highly saline sites and possibly endangered by increasing salinisation. E. sargentii subsp. onesia differs from subsp. sargentii primarily in the lignotuberous, mallee habit, making it preferable to subsp. sargentii for salt reclamation projects, due to its propensity to regenerate following fire or cutting. Extensive field examination, seedling trials and observations of cultivated material have indicated that E. sargentii subsp. fallens is not specifically distinct from E. diminuta and I regard the former as synonymous with the latter. E. diminuta is recircumscribed to include populations from Eurardy Station in the north to near Watheroo in the south.
Re-assessment of the saline-dwelling Eucalyptus spathulata complex (Myrtaceae) from southern Western Australia
NICOLLE, D. AND BROOKER, M.I.H., Nuytsia 15 (3): 403–430 (2005)
The circumscription of taxa within the Eucalyptus spathulata complex is revised. The status of E. vegrandis is resolved and the new species E. orthostemon Nicolle & Brooker is described to accommodate populations of mallees previously and erroneously referred to E. vegrandis. The new taxon E. vegrandis subsp. recondita Nicolle & Brooker is described to accommodate coarse, relatively broad-leaved mallees in the Stirling Range area, previously referred under the manuscript name E. ‘recondita’. E. suggrandis is recircumscribed, with subsp. alipes (as to the type – the mallet/obligate seeder variant) raised to specific status as E. alipes (L. Johnson & K. Hill) Nicolle & Brooker. E. mimica is recircumscribed as an obligate seeder (mallet) species and E. suggrandis subsp. promiscua Nicolle and Brooker described from the Lake Grace – Pingrup area, previously being confused with both E. mimica and E. suggrandis. The new subspecies, E. spathulata subsp. salina Nicolle & Brooker, is described from mallets restricted to the Salt River drainage system of the northern part of the southern wheatbelt. E. cernua is recircumscribed as an obligate seeder (mallet) species with resprouter (mallee) populations, previously included under E. cernua, published as E. proxima Nicolle & Brooker. The manuscript name E. ‘verruculosa’ is considered to be E. suggrandis subsp. suggrandis, as to the proposed type. A key and distribution maps for the E. spathulata complex are provided.
New taxa, a new record and a rediscovery in Western Australian Haloragis (Haloragaceae)
ORCHARD, A.E., LEPSCHI, B.J. AND HISLOP, M., Nuytsia 15 (3): 431–444 (2005)
Variation and distribution in taxa of the Haloragis gossei–H. trigonocarpa group is discussed and two new taxa, H. maierae Orchard and H. gossei var. inflata Orchard are described. Rediscovery of H. platycarpa is noted, and an amended description of this rare species is provided. Variation in the H. aculeata–H. scoparia group is discussed, and a widely disjunct new record, H. glauca forma glauca, is noted for the State.
A taxonomic review of Dicrastylis sect. Corymbosae (Lamiaceae: Chloantheae), incorporating Mallophora as a new synonym
RYE, B.L., Nuytsia 15 (3): 445–456 (2005)
Following a recent recommendation to conserve the name Dicrastylis Drumm. ex Harv. over Mallophora Endl., the two species previously included in the latter genus are here transferred to Dicrastylis sect. Corymbosae Munir. To achieve this, two new combinations, Dicrastylis globiflora (Endl.) Rye and D. rugosifolia (Munir) Rye, are made. The circumscription of Dicrastylis sect.Corymbosae is further altered by the removal of D. nicholasii F. Muell., and D. glauca is reduced to a synonym of D. corymbosa. A review of the section is presented. It is now comprised of five white-flowered species with cymes condensed into corymbosely arranged clusters, and is restricted to the south-west of Western Australia.
A taxonomic update of Petrophile sect. Arthrostigma (Proteaceae)
RYE, B.L. AND HISLOP, M., Nuytsia 15 (3): 457–484 (2005)
Petrophile sect. Arthrostigma (Endl.) Benth. is described, P. teretifolia R. Br. is chosen as its lectotype, and a key is given for all members of the section. Petrophile filifolia R. Br. and P. juncifolia Lindl. are reinstated. Descriptions are also given for five new taxa, Petrophile filifolia subsp. laxa Rye & Hislop, P. pilostyla, P. pilostyla subsp. austrina, P. pilostyla subsp. syntoma and P. prostrata, and for two species that are now more narrowly circumscribed, P. brevifolia R. Br. and P. longifolia R. Br. A lectotype is also selected for P. longifolia. Pollen presenter characters, which are of particular importance in this group, are compared in a table and are illustrated for all of the named taxa.
A new heterocarpidic fruit type for the Myrtaceae, with dehiscent and indehiscent loculi, in two genera from Western Australia
RYE, B.L. AND TRUDGEN, MALCOLM E., Nuytsia 15 (3): 485–494 (2005)
A form of heterocarpidy with dehiscent and indehiscent loculi present in the same fruit is described from species in two genera of Myrtaceae occurring in the south-west of Western Australia. This extreme development of heterocarpidy results in a very unusual fruit type, one that has not previously been described for the Myrtaceae. It is also apparently rare in the angiosperms, although smaller differences between carpels (mostly in their size and the number of seeds) are not uncommon. In Astus Trudgen & Rye and the Baeckea robusta F. Muell. complex, two types of ovary loculi develop, with one type dehiscent by a suture on the floral disc and the other type lower in the ovary and indehiscent. The occurrence of this heterocarpidic fruit type in two fairly different genera is considered to be a convergent development rather than indicating a particularly close relationship. The heterocarpidic fruit in these groups is described and illustrated, and its adaptive and taxonomic significance discussed.
Astus, a new Western Australian genus of Myrtaceae with heterocarpidic fruits
TRUDGEN, MALCOLM E. AND RYE, B.L., Nuytsia 15 (3): 495–512 (2005)
Astus Trudgen & Rye, a new genus of Myrtaceae with four species endemic to the south-west of Western Australia, is described and its affinities discussed. While the genus is circumscribed on the basis of a range of characteristics that separate it from related genera, all its members are unusual in having a fruit with both dehiscent and indehiscent loculi. In addition, two of the species have a marked heteromorphy in their calyx lobes. Astus is one of a number of genera belonging to the tribe Chamelaucieae that have reniform seeds. While the floral morphology of the new genus does not readily indicate which of the other reniform-seeded genera it is closest to, DNA evidence indicates affinities to the Eastern Australian genus Triplarina Raf. The type species, Astus tetragonus (F. Muell. ex Benth.) Trudgen & Rye, is based on Baeckea tetragona F. Muell. ex Benth. Astus duomilius Trudgen & Rye, A. subroseus Trudgen & Rye and A. wittweri Trudgen & Rye are new species. A key to the species, descriptions, illustrations and distribution maps are provided.
Goodenia pedicellata (Goodeniaceae), a new species from the Pilbara bioregion of Western Australia
SAGE, L.W. AND DIXON, K.W., Nuytsia 15 (3): 513–516 (2005)
A new species of conservation priority, Goodenia pedicellata, is described, illustrated, mapped and compared with G. cusackiana (F. Muell.) Carolin. Surveys are needed to accurately determine the rarity of the species in the wild, currently known only from the holotype location.
Rulingia borealis, a new combination based on R. malvifolia var. borealis (Malvaceae s.l. or Sterculiaceae)
WILKINS, C.F., Nuytsia 15 (3): 517–522 (2005)
Rulingia malvifolia Steetz is an illegitimate name since Steetz, in describing R. malvifolia cited Commersonia cygnorum Steud. in synonomy. Pritzel (1901) then described Rulingia malvifolia var. borealis E.Pritz. This variety is here raised to species rank to become R. borealis (E.Pritz.) C.F.Wilkins.
New and noteworthy plant species recognised as naturalised in Western Australia
KEIGHERY, G.J., Nuytsia 15 (3): 523–528 (2005)
The format of this paper follows that of Heenan et al. (2002) for New Zealand and Hosking et al. (2003) for New South Wales. Species are grouped under Monocotyledons or Dicotyledons, then listed aphabetically by family and scientific name, common name (when available), the location of a taxon description, natural region where the weed has been recorded following the Interim Biogeographic Regionalisation for Australia (Thackway & Cresswell 1995), habitats, first records and area of origin.
Dedication - Dr Jennifer Anne (Jenny) Chappill, 1959–2006
LEMSON, K.L., Nuytsia 16 (1): 1–2 (2006)
We dedicate this issue of NUYTSIA to the memory of our friend and colleague, Jennifer Anne Chappill. Jenny made significant contributions to both our knowledge of the Western Australian flora and to the local systematics community, and it is fitting that she be honoured in this way.
Coprinopsis stangliana - a recently introduced fungus expanding in urban bushlands of the Perth region of Western Australia
BOUGHER, N.L., Nuytsia 16 (1): 3–10 (2006)
Successively for the past ten years a distinctive, large fungus superficially resembling the northern hemisphere Magpie Fungus Coprinopsis picacea syn. Coprinus picaceus has been observed for the first time in Western Australia (WA). The fungus is a member of the section Coprinus subsection Alachuani. Based on morphological and habitat attributes, the WA fungus is considered in this paper to be affiliated with Coprinopsis stangliana syn. Coprinus stanglianus. C. stangliana is known from calcareous soil, limestone, and chalk in Europe and Turkey, but has not been confirmed in Australia. In WA, C. stangliana generally has larger fruit bodies than reported for this species elsewhere. The fungus produces abundant fruit bodies in highly disturbed patches within numerous urban bushlands of the Perth region. The apparent recent establishment of such a conspicuous fungus, and observations of its fruiting patterns over successive years suggest that it is rapidly spreading following a relatively recent introduction into the Perth region.
Logania wendyae (Loganiaceae), a new species from south-west Western Australia
CRANFIELD, R.J. AND KEIGHERY, G.J., Nuytsia 16 (1): 11–14 (2006)

DURETTO, M.F., Nuytsia 16 (1): 15–20 (2006)
Boronia barrettiorum Duretto sp. nov. (Boronia subseries Filicifoliae: Rutaceae) is described and its relationships discussed. Variation in B. pauciflora W.Fitz. is also discussed and a key to the species of Boronia found in the Kimberley Region is provided.
Reinstatement of Patersonia occidentalis var. angustifolia and Patersonia occidentalis var. latifolia (Iridaceae)
GIBSON, N., Nuytsia 16 (1): 21–27 (2006)
Patersonia occidentalis R.Br. var. angustifolia Benth. and Patersonia occidentalis R.Br. var. latifolia (F.Muell.)Benth. are reinstated and a lectotype for P. occidentalis var. angustifolia is selected. Both P. occidentalis var. angustifolia and P. occidentalis var. latifolia are endemic to south-west Western Australia. P. occidentalis var. angustifolia occurs along drainage lines and in seasonal swamps while P. occidentalis var. latifolia occurs in drier habitats generally on clays or loams associated with laterite, granite or sandstone. The three varieties can be separated using a combination of leaf width, scape length and leaf aspect ratio.
Contributions to Western Australian orchidology: 3. New and reinstated taxa in Eriochilus
HOPPER, STEPHEN D. AND BROWN, A.P., Nuytsia 16 (1): 29–61 (2006)
The systematics of Western Australian members of Brown’s (1810) genus Eriochilus R.Br. has been controversial, confused and poorly understood. This paper provides a revision drawing upon recent fieldwork, collections and herbarium studies that considerably resolve the taxonomic situation. We describe the following taxa as new: E. helonomos, E. pulchellus, E. valens, E. dilatatus subsp. magnus, E. dilatatus subsp. orientalis, E. dilatatus subsp. undulatus, and E. scaber subsp. orbifolia. New combinations are E. dilatatus Lindley subsp. multiflorus (Lindley) Hopper and A.P. Br. and E. dilatatus Lindley subsp. brevifolius (Benth.) Hopper and A.P. Br. The genus is thus enlarged in Western Australia to 6 species. E. dilatatus is geographically variable, now with six subspecies. E. scaber subsp. orbifolia is the only threatened taxon in Western Australia, known from a single locality near Walpole.
New species of Xanthoria (Teloschistaceae) from Australia
KONDRATYUK, S.Y., KÄRNEFELT, E.I. AND THELL, A., Nuytsia 16 (1): 63–76 (2006)

Acacia splendens (Leguminosae : Mimosoideae), a new rare species from near Dandaragan, Western Australia
MASLIN, B.R. AND ELLIOTT, C.P., Nuytsia 16 (1): 81–86 (2006)
A new species, Acacia splendens Maslin & C.P. Elliott, is described and illustrated. It is most closely related to A. microbotrya Benth. and A. daphnifolia Meisn. and is geographically restricted to near Dandaragan, Western Australia. Acacia splendens is Declared Rare Flora (ranked as Endangered) under the Western Australian Wildlife Conservation Act 1950 and is also listed as Endangered under Commonwealth legislation.
Formal recognition of Eucalyptus platydisca (Myrtaceae), an arid-zone monocalypt from south-western Australia
NICOLLE, D. AND BROOKER, M.I.H., Nuytsia 16 (1): 87–94 (2006)
The new species Eucalyptus platydisca is formally described, the species having been long recognised as a distinct taxon under the manuscript name E. platydisca and under various phrase names including the common name Jimberlana mallee. The new species is known from just two populations near Norseman in Western Australia and is included in Western Australia’s Schedule of Declared Rare (Endangered) Flora. The new species is closely related to, but readily distinguishable from, E. diversifolia, differing in the narrower juvenile leaves, the consistently 7-flowered inflorescences, the longer, conical to horn-shaped operculum, the broader fruits with a consistently broad disc and the granite hill habitat. Eucalyptus platydisca is probably a relictual species and occurs in the lowest rainfall environment of any monocalypt (Eucalyptus subgenus Eucalyptus). The new species is part of E. subser. Neuropterae, and a key for the subseries is presented.
A review of the tuberous Calandrinia species (section Tuberosae), including three new species for Western Australia
OBBENS, F.J., Nuytsia 16 (1): 95–115 (2006)
Background on the current systematic status of Australian Calandrinia is explained. Three new species of section Tuberosae von Poellnitz are described and illustrated: Calandrinia crispisepala Obbens, C. kalanniensis Obbens and C. translucens Obbens. A key to section Tuberosae is provided. Additional descriptive material for the previously named species is provided along with notes that explain the important differences and similarities between the six species now belonging to this section.
A partial revision of the south-western Australian species of Micromyrtus (Myrtaceae: Chamelaucieae)
RYE, B.L., Nuytsia 16 (1): 117–147 (2006)
This partial revision of the genus Micromyrtus Benth., deals mainly with species that have a ten-ribbed hypanthium, but excludes the M. racemosa complex. All of the new species are endemic to the south-west of Western Australia. Eight taxa are named: M. acuta Rye, M. chrysodema Rye, M. clavata J.W. Green ex Rye, M. elobata subsp. scopula Rye, M. placoides Rye, M. navicularis Rye, M. redita Rye and M. triptycha Rye. A key is given for Western Australian members of the genus. Micromyrtus is compared with its close relative Corynanthera J.W. Green, and the morphological specialisations of both genera and their possible affinities to other genera in tribe Chamelaucieae are discussed. The compressed winged diaspore of Corynanthera, which has the peduncle fused to both the bracteoles and fruit, is of particular interest, and an illustration compares it with diaspores from five- and ten-ribbed species of Micromyrtus.
New combinations and lectotypifications for the south-western Australian genus Astartea (Myrtaceae)
RYE, B.L., Nuytsia 16 (1): 149–156 (2006)
Three new combinations, Astartea affinis (Endl.) Rye, A. arbuscula (Benth.) Rye and A. astarteoides (Benth.) Rye, are made for species that were initially described in the genus Baeckea L. Lectotypes are selected for two of the base names, Baeckea affinis Endl. (including its synonym Astartea endlicheriana Schauer nom. illeg.) and B. astarteoides Benth., and also for Astartea laricifolia Schauer.
Three new species of Lechenaultia (Goodeniaceae) from south-west Western Australia, and a new key to the genus
SAGE, L.W., Nuytsia 16 (1): 157–166 (2006)
The new species, Lechenaultia galactites L.W. Sage, L. magnifica L.W. Sage and L. hortii L.W. Sage are described and illustrated. All three species are known from the South West Botanical province of Western Australia and all have conservation priority. A new key to Lechenaultia is provided.
New taxa of Goodenia subgenus Goodenia section Caeruleae subsection Scaevolina (Goodeniaceae), from the Eremaean Botanical Province of Western Australia

Goodenia hartiana L.W. Sage and G. azurea subsp. hesperia L.W. Sage & Albr. are described, illustrated and mapped with notes on the distribution, conservation status, habitat preferences and relationships to other taxa. Keys to distinguish the new taxa are also provided.
Lasiopetalum pterocarpum (Malvaceae s.l.: Lasiopetaleae), a new and and rare species from south-west Western Australia
SHEPHERD, K.A., BENNETT, ELEANOR M., WILKINS, C.F. AND SAGE, L.W., Nuytsia 16 (1): 175–181 (2006)
Lasiopetalum pterocarpum E.M. Benn. & K.A. Sheph. sp. nov. is described and illustrated. The distinct winged fruit, for which L. pterocarpum is named, is unique within Lasiopetaleae. Lasiopetalum pterocarpum is allied to L. floribundum, which shares a similar habit, large ovate leaves and loose dichasial inflorescences. It can be readily distinguished from L. floribundum by its discolorous and strongly-lobed leaves, the absence of glandular hairs on the peduncles, and its larger seeds. This species is known from only one population south of Perth and is classified as critically endangered.
Stylidium diplotrichum (Stylidiaceae): a new scale-leaved trigger plant from south-west Western Australia, with taxonomic and anatomical notes on allied species
WEGE, J.A., Nuytsia 16 (1): 183–197 (2006)
A new scale-leaved trigger plant with conservation priority, Stylidium diplotrichum Wege, is described and illustrated. Revised taxonomic descriptions and notes are also provided for the priority species S. pseudohirsutum Mildbr. and S. expeditionis Carlquist, and the more commonly occurring S. hirsutum R.Br. and S. crossocephalum F.Muell. Leaf anatomy data are provided for all species. The location of the stomata is shown to be taxonomically informative.
Reinstatement of Stylidium rigidulum (Stylidiaceae), with notes on the morphologically allied S. kalbarriense
WEGE, J.A., Nuytsia 16 (1): 199–206 (2006)
Stylidium macrocarpum (Benth.) F.L.Erickson & J.H.Willis and S. leptophyllum DC. var. glabrescens Mildbr. are placed into synonymy under S. rigidulum Sond. and a revised taxonomic description provided. A modified description is also provided for the morphologically allied S. kalbarriense Lowrie & Kenneally. A chromosome number of n = 13 is reported for S. kalbarriense, and a count of n = 11 confirmed for S. rigidulum. These species are noted to grow in sympatry east of Dongara. Both taxa are susceptible to infection by the rust Puccinia stylidii McAlpine.
Taxonomic notes on the locket trigger plants from Stylidium subgenus Tolypangium section Repentes
WEGE, J.A., Nuytsia 16 (1): 207–220 (2006)
Two new trigger plants from south-west Western Australia, Stylidium perula Wege and Stylidium thylax Wege, are described and illustrated. Revised descriptions are provided for the morphologically allied S. sacculatum F.L.Erickson & J.H.Willis and S. pseudosacculatum Lowrie, A.H. Burb. & Kenneally. Features of trichome structure are argued to provide important taxonomic characters at the species level in Stylidium. The morphology and function of the column cunabulum is explored.
Taxonomic observations on the Stylidium leptocalyx complex (Stylidiaceae)
WEGE, J.A., Nuytsia 16 (1): 221–231 (2006)
The name Stylidium leptocalyx Sond. has been misapplied for many years. This trigger plant is now recognised to be of restricted distribution in the wandoo country south-west of York, and is characterised by pink flowers with linear calyx lobes, arranged in a loose, corymb-like raceme. Stylidium stenosepalum E.Pritz. is reinstated to account for the northern sandplain entity previously known as S. leptocalyx. This species differs from S. leptocalyx in possessing white flowers with a longer corolla tube and column. Amended descriptions and floral images are provided for both species, along with the morphologically-allied S. scabridum Lindl.
Taxonomic observations on Stylidium spathulatum (Stylidiaceae), with the description of three allied species from section Saxifragoidea
WEGE, J.A., Nuytsia 16 (1): 233–246 (2006)
Stylidium spathulatum R.Br. (n=14) is lectotypified and a revised species description provided. On the basis of cytological and morphological evidence Stylidium planirosulum Wege (n=13) and S. glandulosissimum Wege (n=13) are described as new. A third morphologically allied species with conservation priority, Stylidium gloeophyllum Wege, is also described. Variation in trichome structure and distribution is shown to be highly diagnostic. Illustrations are provided for the three new species.
Stylidium hymenocraspedum (Stylidiaceae) - a new species for Western Australia, and the lectotypification of S. maitlandianum
WEGE, J.A., Nuytsia 16 (1): 247–253 (2006)
A new species of trigger plant with conservation priority, Stylidium hymenocraspedum Wege, is described and illustrated. The morphologically allied S. maitlandianum E.Pritz. is lectotypified and an amended taxonomic description provided.
Rhetinocarpha (Asteraceae : Gnaphalieae) - a new genus from Western Australia
WILSON, PAUL G. AND WILSON, M.A., Nuytsia 16 (1): 255–260 (2006)
Myriocephalus suffruticosus Benth. is transferred to a new genus Rhetinocarpha Paul G. Wilson & M.A. Wilson. One new species combination is made: R. suffruticosa (Benth.) Paul G. Wilson & M.A. Wilson.
A new rare and geographically restricted Ptilotus (Amaranthaceae) from the Pilbara Bioregion of Western Australia
DAVIS, R.W., Nuytsia 16 (2): 265–268 (2007)
A distinctive, rare and geographically restricted species, Ptilotus subspinescens R.W. Davis (Amaranthaceae), is described from the Pilbara Bioregion of Western Australia. Ptilotus subspinescens is only known from several small populations adjacent to the Brockman mine site, 100 km west-south-west of Wittenoom.
Ficus carpentariensis - a new sandpaper fig for northern Australia and a revision of the F. opposita complex (Moraceae: Ficus subg. Ficus sect. Sycidium informal group F. copiosa)
DIXON, D.J., Nuytsia 16 (2): 269–284 (2007)
The Ficus opposita Miq. complex is revised. Four taxa in three species are recognized, F. opposita from Queensland and Papua New Guinea, Ficus aculeata Miq. with two varieties, one, var. aculeata occurring across the tropical north of Australia, the other, var. indecora (Miq.) D.J. Dixon restricted to the Northern Territory and Western Australia. A new species Ficus carpentariensis D.J. Dixon which is endemic to the Northern Territory is described. A key to identification is provided along with distribution and habitat and typification notes. Type material has been lectotypified where necessary.
A new species and a new combination in Acrotriche (Ericaceae: Styphelioideae: Styphelieae), with keys to the Western Australian members of the genus and its closest relative Lissanthe
HISLOP, M., Nuytsia 16 (2): 285–297 (2007)
Descriptions, illustrations and distribution maps are given for a new species, Acrotriche lancifolia Hislop and its closest relative A. patula R.Br. with which it has hitherto been confused. A lectotype is also selected for A. patula. A new combination, A. parviflora (Stschegl.) Hislop is made. The case is argued for the removal of A. depressa R.Br. from the West Australian plant census. Keys are provided at the generic level to separate Acrotriche R.Br. from Lissanthe R.Br. and at the species level for all Western Australian members of these two related genera.
Blackallia, Serichonus and Papistylus: three closely related genera of Rhamnaceae (Pomaderreae) from south-western Australia
KELLERMANN, J., RYE, B.L. AND THIELE, K.R., Nuytsia 16 (2): 299–316 (2007)
Recent molecular and morphological studies of Pomaderreae indicate that a number of species that have traditionally been of uncertain affinity require new genera. Blackallia C.A. Gardner is lectotypified and restricted to one species, B. nudiflora (F. Muell.) Rye & Kellermann, for which a new combination is made. Two new genera are described, Serichonus K.R. Thiele comprising the single species S. gracilipes (Diels) K.R. Thiele, and Papistylus Kellermann, Rye & K.R. Thiele with two species, P. grandiflorus (C.A. Gardner) Kellermann, Rye & K.R. Thiele and the new species P. intropubens Rye. All three genera are restricted to the South West Botanical Province of Western Australia. They are closely related but can be readily distinguished from one another by some significant morphological differences, especially in their inflorescences. A revised key to the genera of Pomaderreae is presented and lectotypes are chosen for B. nudiflora and S. gracilipes.
A new species of Hypoxis (Hypoxidaceae) from saline wetland margins in Western Australia
LYONS, M.N. AND KEIGHERY, G.J., Nuytsia 16 (2): 317–320 (2007)
A new species, Hypoxis salina Lyons & Keighery, is described and illustrated. The species is confined to the margins of naturally saline wetlands in the Mallee Bioregion of southern Western Australia.
Drosera gibsonii (Droseraceae), a new Pygmy Drosera from south-west Western Australia
MANN, P., Nuytsia 16 (2): 321–323 (2007)
Drosera gibsonii (Drosera subgenus Rorella section Lamprolepis) is described from the Stirling Range National Park. Its closest relative is Drosera silvicola Lowrie & Carlquist and the features that distinguish this taxon from Drosera gibsonii are presented together with its habitat preferences and conservation status.
New species and keys for Cryptandra and Stenanthemum (Rhamnaceae) in Western Australia
RYE, B.L., Nuytsia 16 (2): 325–382 (2007)
A generic key for the Rhamnaceae of central and southern Western Australia and keys to Western Australian members of Cryptandra Sm. and Stenanthemum Reissek are given. Two taxa previously described as varieties are raised to the species level with the new combination Cryptandra intermedia (Rye) Rye and the new name C. multispina Rye. The new taxa Cryptandra beverleyensis Rye, C. craigiae Rye, C. crispula Rye, C. dielsii C.A. Gardner ex Rye, C. exserta Rye, C. imbricata Rye, C. inconspicua Rye, C. pendula Rye, C. micrantha Rye, C. stellulata Rye, Stenanthemum bremerense Rye, S. pumilum subsp. majus Rye, S. radiatum Rye and S. yorkense Rye are described. Lectotypes are selected for Cryptandra connata C.A. Gardner and for the base name of Cryptandra sect. Wichurea Benth. Some of the newly named taxa are illustrated, distribution maps are given for the south-western species of Cryptandra and new taxa in Stenanthemum, and the distribution patterns of the south-western genera are discussed in relation to their morphology. There is also a generic description for Cryptandra, and new data are given for a few of the previously described taxa in both genera.
Tecticornia bibenda (Chenopodiaceae: Salicornioideae), a new C4 samphire from the Little Sandy Desert, Western Australia
SHEPHERD, K.A. AND VAN LEEUWEN, S., Nuytsia 16 (2): 383–391 (2007)
Tecticornia bibenda K.A. Sheph. & S.J. van Leeuwen, a new species of conservation significance is described and illustrated. Previously Tecticornia indica (Willd.) K.A. Sheph. & Paul G. Wilson (formerly Halosarcia indica (Willd.) Paul G. Wilson) was the only member of the Salicornioideae that was known to have a modified Kranz anatomy indicative of the C4 photosynthetic pathway. Anatomical evidence indicates that T. bibenda shares a similar modifi ed anatomy. While T. bibenda is related to T. indica, it is distinguished by the presence of unusually large vegetative and fertile articles and having paired cymes of (4)5–7 flowers rather than the more typical 3-flowered cymes. This species is restricted to the flood zones and fringing spinifex/samphire heath of several gypsiferous playa and salt lake systems in the Little Sandy Desert of Western Australia. Due to its restricted distribution this species has a Priority three conservation status.
A revision of the Western Australian genus Agonis (Myrtaceae) and two new segregate genera Taxandria and Paragonis
WHEELER, J.R. AND MARCHANT, N.G., Nuytsia 16 (2): 393–433 (2007)
Two new genera, Taxandria (Benth.) J.R. Wheeler & N.G. Marchant (11 species) and the monotypic Paragonis J.R.Wheeler & N.G. Marchant are segregated from Agonis (DC.) Sweet s. str. (4 species). The three genera are revised; all are endemic to the south-west of Western Australia and together comprise 16 species. Two new species are described, two species reinstated and several new combinations and lectotypifications are made. Keys are provided to the three genera and their taxa. All taxa are illustrated and mapped.
Puccinellia (Poaceae) in Western Australia
WILLIAMS, A.R., Nuytsia 16 (2): 435–467 (2007)
Two new native species, Puccinellia longior and P. vassica, have been identified from Western Australia. P. longior is restricted to the outer edges of salt lakes and salt-affected pasture land along the lower western margin of the southwest wheatbelt region in WA, and has also been collected from a saline wetland reserve in southeast South Australia. P. vassica is endemic to the outer edges of marine saltmarsh in reserved areas of the Leschenault Inlet near Bunbury. It was previously known from the nearby Vasse-Wonnerup saltmarsh near Busselton but is now extinct there because engineering works have reduced the marine influence in the estuary. It may be on the verge of extinction in the Leschenault Inlet also because (a) it lives on the outer edge of the high tide influence and is thus prone to weed invasion from non-saline areas, (b) its culms disintegrate almost entirely each year so it provides little resistance to competition, and (c) it has a low recruitment rate, with only a few scattered plants surviving at each site. The most common species is Puccinellia stricta, which occurs on the margins of salt lakes and salt-affected pastoral land throughout the southwest wheatbelt region, from Hutt River in the north to the Esperance region in the east. WA collections of this species differ from those elsewhere in southern Australasia, but in a continuous way that did not easily yield taxonomic distinction. The main source of variation is probably that the WA habitats all have to endure long summer drought each year. The agriculturally introduced Middle-Eastern species P. ciliata is well naturalized in saline lands in southwest WA, and a single collection of the introduced P. gigantea is recorded. Other introduced species appear to have not survived.
Occurrence and status of Pentapogon quadrifidus (Poaceae) in Western Australia
MACFARLANE, T.D. AND HEARN, R.W., Nuytsia 16 (2): 469–471 (2007)
Pentapogon quadrifidus is thus known from three separate locations where it grows in consistent habitats among native vegetation in good condition. At each site it is scattered through the vegetation at varying densities but never dominating. From this pattern we concluded that the species is most likely to be native to Western Australia. We assume that it has been overlooked because it occurs in only a few sites, is inconspicuous, and superfi cially resembles Austrodanthonia species, especially A. setacea. Because of its apparently localised distribution it had a Priority 1 conservation rating for Western Australia in Atkins (2006). It is now considered to carry a Conservation Code for Western Australian Flora: Priority 2 following the discovery of the population in a nature reserve. This survey has achieved some of the management requirements listed for this species by Hearn et al. (2006).
Agrostis castellana (Poaceae) mis-identified as A. capillaris var. aristata in Western Australia
MACFARLANE, T.D. AND WILLIAMS, A.R., Nuytsia 16 (2): 472 (2007)
In the process of assisting with the updating of Western Weeds: a Guide to the Weeds of Western Australia (Hussey & Keighery 1997) we became aware that Batson (1998) had identified Agrostis castellana Bois. et Reuter as the dominant species in ‘bent grass’ pastures in South-eastern Australia, which had previously been reported as being dominated by A. capillaris L. (syn. A. tenuis Sibth.).
Recombinations in Western Australian Orchidaceae 1
THIELE, K.R. AND BROWN, A.P., Nuytsia 16 (2): 473–474 (2007)
Two new species from Western Australia were recently described under the segregate genera Hydrorchis (Jones and Brockman 2005) (= Microtis) and Oligochaetochilus (Jones 2004) (= Pterostylis). This paper provides the necessary recombinations of these new taxa into the genera accepted at PERTH, in order that they may be dealt with adequately in Western Australia. Future short communications in this series will deal with any further taxa so described, until a broadly accepted consensus is reached with respect to the boundaries of these genera.
Further recombinations of Dryandra into Banksia
THIELE, K.R. AND MAST, A.R., Nuytsia 16 (2): 475 (2007)
Mast and Thiele (2007), in order to resolve a problem caused by the paraphyly of Dryandra with respect to Banksia, reduced the former genus to a synonym of the latter, and published new combinations for the majority of Dryandra taxa in Banksia. However, a paper by George (2005), describing one new species and five new infraspecies of Dryandra, was overlooked at the time. Accordingly, these taxa require new combinations in Banksia.
Taxonomic research and the conservation status of flora in the Yilgarn Banded Iron Formation ranges
GIBSON, N., COATES, D.J. AND THIELE, K.R., Nuytsia 17: 1–12 (2007)
The Banded Iron Formation (BIF) ranges are small, ancient ranges scattered across the Yilgarn Craton in southern Western Australia. Increased exploration and mining of iron ore in Western Australia has resulted in a resurgence of botanical survey on and around the BIF ranges, including the discovery of at least 20 unnamed taxa, nine of which were new to science. Recent taxonomic work, published in this special edition of Nuytsia, has concentrated on naming 17 taxa with distributions centred on these ranges and a further 62 taxa of conservation significance in the southern half of Western Australia. Despite this increase in activity, the conservation status of the flora and vegetation remains poorly documented. Patterns in distribution of threatened, rare and poorly known taxa (Declared Rare Flora and Priority Flora) and patterns in endemism are examined on a subset of the 25 ranges most prospective for mining. Preliminary analysis of endemism supports the hypotheses that these ranges represent both refugial habitats of great antiquity and areas of recent speciation. Across Western Australia there are some 2,240 taxa under consideration for formal listing by the Department of Environment and Conservation as threatened; of these, 475 are yet to be formally named. This situation significantly impedes their conservation assessment.
Two newly described species and a draft key to the species of Sida s.lat. from Western Australia
BARKER, R.M., Nuytsia 17: 13–30 (2007)
There are a number of new native species of Sida listed in the Western Australian Herbarium’s FloraBase that have not yet been formally described. Of the 56 accepted species names presently listed, nearly half represent undescribed taxa. These are cited as either manuscript or phrase names. Two of the species, Sida ectogama W.R.Barker & R.M.Barker and Sida arsiniata R.M.Barker, previously known by phrase names, are here described and a draft key is provided for the native species of Sida found in Western Australia.
Corymbia cadophora subsp. polychroma (Myrtaceae): a new subspecies from the east Kimberley region of Western Australia
BARRETT, R.L., Nuytsia 17: 31–36 (2007)
A new subspecies of Corymbia cadophora K.D.Hill & L.A.S.Johnson is described from the east Kimberley region of Western Australia. The new subspecies, Corymbia cadophora subsp. polychroma R.L.Barrett, is only known from a single location where it grows on sandstone adjacent to a banded ironstone deposit on the western side of the Ragged Range. A key is provided to all three subspecies of C. cadophora.
New species of Lepidosperma (Cyperaceae) associated with banded ironstone in southern Western Australia
BARRETT, R.L., Nuytsia 17: 37–60 (2007)
Eight new species in the Australasian genus Lepidosperma Labill. are described from southern Western Australia. All of the taxa described here have restricted distributions in association with Banded Iron Formation (BIF) ranges and are potentially threatened by present or proposed mining activities. The following new species are described: L. amansiferrum R.L.Barrett, L. bungalbin R.L.Barrett, L. diurnum R.L.Barrett, L. ferricola R.L.Barrett, L. ferriculmen R.L.Barrett, L. gibsonii R.L.Barrett, L. jacksonense R.L.Barrett and L. lyonsii R.L.Barrett.
Lepidosperma gahnioides, a new species of Cyperaceae from the Ravensthorpe region, Western Australia
BARRETT, R.L., Nuytsia 17: 61–66 (2007)
Lepidosperma gahnioides R.L.Barrett is here described as a new species. This species has a restricted distribution from the Ravensthorpe Range north to Lake Ace, in southern Western Australia, and is potentially threatened by present and proposed mining activities.
Lasiopetalum ferraricollinum (Malvaceae s. lat.: Lasiopetaleae), a new species from the ironstone hills near Forrestania, Western Australia
BENNETT, ELEANOR M. AND SHEPHERD, K.A., Nuytsia 17: 67–72 (2007)
Lasiopetalum ferraricollinum E.M.Benn. & K.A.Sheph. is a new species restricted to a number of ironstone outcrops in the Coolgardie (COO) and Mallee (MAL) IBRA regions. This species, while morphologically allied to L. compactum Paust, is characterised by recurved leaf margins, white to cream flowers and the presence of both scattered stellate hairs and glandular hairs on the outside of the calyx. A description, distribution map, and images of the new species are provided.
Caladenia petrensis and C. saxicola (Orchidaceae), two new ironstone endemics from south-west Western Australia
BROWN, A.P. AND BROCKMAN, G., Nuytsia 17: 73–80 (2007)

Four new conservation-listed species of Synaphea (Proteaceae: Conospermineae) from the Jarrah Forest region of south-west Western Australia
BUTCHER, R., Nuytsia 17: 97–116 (2007)
The new species described here are a diverse assemblage of taxa, united in this paper by their geographical occurrence within the Jarrah Forest region of south-west Western Australia and a pressing need to formalise the description of conservation taxa in this State. The taxa have complex taxonomic associations within the groups to which they belong, with intergradation in many characters evident between species. The new species described herein are S. diabolica R.Butcher, S. pandurata R.Butcher, S. polypodioides R.Butcher and S. trinacriformis R.Butcher. A distribution map, image and discussion of affinities are provided for each taxon.
Tetratheca exasperata and T. phoenix (Elaeocarpaceae), two new conservation-listed species allied to T. setigera, from south-west Western Australia
BUTCHER, R., Nuytsia 17: 117–126 (2007)
The two new species described here are similar to Tetratheca setigera Endl. in having the upper part of the pedicel, the receptacle and the calyx segments densely ornamented with long, red, glandular setae. Tetratheca exasperata R.Butcher differs most readily from T. setigera in its almost glabrous leaves, with strongly revolute margins, and very short, patent stem hairs. This taxon has been infrequently collected from three areas in the Jarrah Forest and Avon Wheatbelt regions and has a Priority Three conservation listing. Tetratheca phoenix R.Butcher differs from T. setigera in its almost glabrous, but prominently tuberculate, stems and densely glandular-hairy ovary. This taxon is restricted to Mt Cooke, c. 70 km south-east of Perth and has a Priority Two conservation listing. These two new species are described and illustrated here, and their distributions are mapped.
Tetratheca pilata (Elaeocarpaceae), a new and apparently rare species from the Ongerup area of south-west Western Australia
BUTCHER, R., Nuytsia 17: 127–134 (2007)
Tetratheca pilata R.Butcher is described here as a new species and differentiated from similar taxa based on the prominent apical seta on its linear leaves and its more or less opposite-decussate phyllotaxis. Tetratheca pilata is an apparently rare, granite endemic from the Ongerup area and is listed as Priority One under the Department of Environment and Conservation’s Conservation Codes for Western Australian Flora. Images of this taxon and a distribution map are provided.
Persoonia manotricha (Proteaceae: Persoonioideae), a new species associated with Banded Iron Formation ranges in the Midwest region, Western Australia
BUTCHER, R. AND MARKEY, A.S., Nuytsia 17: 135–146 (2007)
The new species, Persoonia manotricha A.S.Markey & R.Butcher, is morphologically similar to P. bowgada P.H.Weston and P. hexagona P.H.Weston in its habit, in having six alternating grooves and ridges on its subterete, pungent leaves and in its floral structure. While its leaf morphology and anatomy closely ally P. manotricha with P. bowgada, the new species can be distinguished by its longer pedicels and by its flowers being less pubescent with a glabrous to sparsely pubescent ovary, similar to those of P. hexagona. Comparative leaf anatomy confirms that P. hexagona is distinctly different in having relatively broad longitudinal grooves in its leaves. The characteristic darkness of these broad grooves, in dried specimens, is not exclusively the result of the stomatal guard cells blackening, as previously thought, but also results from the greater visibility of the underlying mesophyll. Persoonia manotricha is commonly found on the lower, rocky slopes of Banded Iron Formation (BIF) ranges in tall Acacia dominated shrubland. A taxonomic description of the new species, including images and a distribution map, is provided. The new species is integrated into the most recently published key to Persoonia species.
Prostanthera ferricola (Lamiaceae), a new species from Western Australia
CONN, BARRY J. AND SHEPHERD, K.A., Nuytsia 17: 147–152 (2007)
Prostanthera ferricola B.J.Conn & K.A.Sheph., a distinctive new species endemic to ironstone and quartzite hills in the northern Yilgarn region of Western Australia, is described. This species is readily distinguished from P. centralis B.J.Conn and P. magnifica C.A.Gardner by its smaller leaves (5.5–10 mm long), purple-mauve adaxial surface of the calyx, a larger corolla (18–20 mm long) with hairs and glands on the outer surface, an absence of trichomes on the dorsal surface of the connective of the anthers and a longer pistil (20–21 mm long). Images of the holotype and field photographs of the habit and inflorescence are included along with a distribution map.
A new species of Petrophile (Proteaceae) from south-western Australia
CRANFIELD, R.J. AND MACFARLANE, T.D., Nuytsia 17: 153–158 (2007)
A new species, Petrophile vana Cranfield & T.Macfarlane, is described from the Murchison and Yalgoo Bioregions of Western Australia. The new species is known from only three localities where it grows on laterite breakaway ridges.

HOPPER, STEPHEN D. AND NICOLLE, D., Nuytsia 17: 185–194 (2007)
Eucalyptus rhomboidea Hopper & D.Nicolle, first collected by the late Ken Newbey in 1979, is described as new. The species is a member of Eucalyptus ser. Subulatae Blakely allied to E. transcontinentalis Maiden. It is confined to the Bremer Range, and it is at risk from present and proposed mining activities.
New species of Andersonia (Ericaceae) of conservation concern
LEMSON, K.L., Nuytsia 17: 195–214 (2007)
Six new species of Andersonia R.Br. – A. annelsii Lemson, A. ferricola Lemson, A. geniculata Lemson, A. redolens Lemson, A. hammersleyana Lemson and A. pinaster Lemson – are described, mapped and illustrated.
A new species of Neurachne (Poaceae) from Western Australia
MACFARLANE, T.D., Nuytsia 17: 215–222 (2007)
Neurachne annularis T.Macfarlane is described and illustrated with photographs and a distribution map. The new species forms Triodia-like hummocks and grows on and around banded ironstone ranges in the Yilgarn region of Western Australia where it is often dominant in the understorey. The species has the C₃ photosynthetic pathway and is diploid with n = 9, one of three species with that combination in a genus now of seven species. It is morphologically closest to N. tenuifolia S.T.Blake, from ranges in Central Australia.
Wurmbea inflata (Colchicaceae), a new species from the Gascoyne region of Western Australia
MACFARLANE, T.D. AND CASE, A.L., Nuytsia 17: 223–228 (2007)

MASLIN, B.R., Nuytsia 17: 241–246 (2007)
Acacia burrowsiana Maslin, a new species of Acacia Mill. referable to sect. Juliflorae (Benth.) Maiden & Betche is described. It occurs in the south-west arid zone of Western Australia where it is known from only near Mt Magnet and Sandstone. Acacia burrowsiana was listed under its phrase name, Acacia sp. Mt Magnet (T. McKenzie 5), as a Priority One species under the Department of Environment and Conservation’s Conservation Codes for Western Australian Flora.
Acacia cockertoniana (Leguminosae: Mimosoideae), a new species from banded ironstone ranges of the south-west arid zone, Western Australia
MASLIN, B.R., Nuytsia 17: 247–252 (2007)
Acacia cockertoniana Maslin, a new species with a restricted distribution in the south-west arid zone of Western Australia is described. The species is restricted to banded ironstone ranges which accounts for its discontinuous distribution between Mt Jackson (130 km north of Southern Cross) and near Mt Magnet (c. 270 km north-west of Mt Jackson). Sterile specimens from north of Mt Magnet require confirmation as being this species. Acacia cockertoniana is often abundant in the places where it occurs and current evidence suggests that it is most common in the vicinity of the Windarling Range. Acacia cockertoniana appears to be most closely related to A. balsamea Cowan & Maslin.
Two new species of Acacia (Leguminosae: Mimosoideae) from the Koolanooka Hills in the northern wheatbelt region of south-west Western Australia
MASLIN, B.R. AND BUSCUMB, C., Nuytsia 17: 253–262 (2007)
The following two new species of Acacia from the Koolanooka Hills, a low banded ironstone range in the northern wheatbelt region of south-west Western Australia (east of Morawa), are described: Acacia graciliformis Maslin & Buscumb and Acacia muriculata Maslin & Buscumb. Both are listed as Priority One species according to the Department of Environment and Conservation’s Conservation Codes for Western Australia Flora.
Two new Acacia species (Leguminosae: Mimosoideae) from banded ironstone ranges in the Midwest region of south-west Western Australia
MASLIN, B.R. AND BUSCUMB, C., Nuytsia 17: 263–272 (2007)
The following two new species of Acacia Mill. from an area of banded ironstone in the Midwest region of south-west Western Australia (between Morawa and Paynes Find) area are described: Acacia karina Maslin & Buscumb and A. woodmaniorum Maslin & Buscumb. Both species are listed as a Priority Two species according to the Department of Environment and Conservation’s Conservation Codes for Western Australian Flora.
Two new Western Australian species of Drummondita (Rutaceae: Boronieae) from banded ironstone ranges of the Yilgarn Craton
MEISSNER, R.A. AND MARKEY, A.S., Nuytsia 17: 273–280 (2007)
Two new species of Drummondita Harv. are described, both of which occur on rocky hillsides on the Yilgarn Craton of Western Australia. One of these, D. fulva A.S.Markey & R.A.Meissn., has close affinities to D. microphylla Paul G.Wilson but differs in having a reddish apiculus on the leaf apex, tawny new growth, and sub-orbicular, flattened sepals. The other, D. rubroviridis R.A.Meissn, is closely allied to D. wilsonii F.H.Mollemans, from which it is distinguished by a combination of spreading leaves, solitary, larger red flowers with green petal lobes, and a pointed apical leaf gland. Drummondita fulva is relatively widespread, occurring on both Banded Iron Formation and associated metasedimentary rocks in the Yalgoo region, while D. rubroviridis has a restricted distribution and appears to be endemic to a single banded ironstone range in the Koolanooka Hills. A taxonomic description of these two new species, images and maps of their respective distributions are provided.
A new geographically disjunct and apparently rare subspecies of Eucalyptus jutsonii (Myrtaceae) from Western Australia
NICOLLE, D. AND FRENCH, M.E., Nuytsia 17: 281–288 (2007)
The newly discovered subspecies E. jutsonii Maiden subsp. kobela D.Nicolle & M.E.French is described, differing from the typical subspecies in the narrower adult leaves, the generally more slender flower buds with a more pointed operculum and the slightly smaller fruits. The new subspecies is disjunct from the typical subspecies by over 400 kilometres and is known from a single site spanning approximately five kilometres. Eucalyptus jutsonii subsp. kobela may be under threat from mining-related activity and the subspecies meets the criteria for listing as Priority One under the Conservation Codes for Western Australian Flora. A key to E. ser. Micrantherae is included.
A review of the sectional classification of Dicrastylis (Lamiaceae: Chloantheae) and four new arid-zone species from Western Australia
RYE, B.L., Nuytsia 17: 289–324 (2007)
A new delimitation is proposed for three of the sections (Pyramidatae Munir, Spicatae Munir and Verticillatae Munir) of the genus Dicrastylis Drumm. ex Harv. Keys are given to the five sections of the genus and to the 15 Western Australian species of sections Pyramidatae and Spicatae. Four new species from the arid and semi-arid zones of Western Australia are described as Dicrastylis cundeeleensis Rye, D. kumarinensis Rye, D. mitchellii Rye and D. subterminalis Rye. Dicrastylis petermannensis Munir is reduced to a synonym of D. gilesii F.Muell., D. microphyllum Munir to a synonym of D. flexuosa (W.R.Price) C.A.Gardner, and D. georgei Munir is tentatively treated as a synonym of D. cordifolia Munir. None of the previously published subspecies, varieties and forms for any members of the genus is recognised formally here. However, further study of several species complexes occurring in the arid zone is needed as they are extremely variable and taxonomically difficult.
Micromyrtus trudgenii (Myrtaceae: Chamelaucieae), a new species from the Blue Hill Range area of south-western Australia
RYE, B.L., Nuytsia 17: 325–330 (2007)
The new species Micromyrtus trudgenii Rye has conservation priority, being restricted to banded ironstone or dolerite hills in a small area south-east of Yalgoo in Western Australia. It is closely related to M. racemosa Benth., differing in its more elongate leaves with a distinct mucro, its yellow flowers and the almost parallel longitudinal slits on its anthers.
Five new conservation-listed species of Goodenia (Goodeniaceae) from southern Western Australia
SAGE, L.W. AND SHEPHERD, K.A., Nuytsia 17: 331–346 (2007)

Pityrodia iphthima (Lamiaceae), a new species endemic to banded ironstone in Western Australia, with notes on two informally recognised Pityrodia
SHEPHERD, K.A., Nuytsia 17: 347–352 (2007)
Pityrodia iphthima K.A.Sheph. is a new species recently discovered on a single banded ironstone outcrop north of Meekatharra. This species is allied to the declared rare P. augustensis Munir, but is morphologically distinct in having discolorous leaves, larger, ovate bracts, longer calyx tube, shorter branched hairs on the outer surface of the calyx and shorter filaments. Distribution and habit images of P. iphthima are provided. In addition, the informal taxon Pityrodia sp. Dalwallinu (M. Hislop 1860) is synonymised with P. bartlingii (Lehm.) Benth.
Three new species of Tecticornia (formerly Halosarcia) (Chenopodiaceae: Salicornioideae) from the Eremaean Botanical Province, Western Australia
SHEPHERD, K.A., Nuytsia 17: 353–366 (2007)
Three new samphires that occur on saline floodways and around salt lakes in the semi-arid and arid zones of the Eremaean Botanical Province are described. Tecticornia cymbiformis K.A.Sheph. & Paul G.Wilson, a conservation Priority listed species currently known from three disjunct populations, has been recognised as distinct for a number of years but has never been formally described. A second Priority species, T. mellaria K.A.Sheph., is only found on gypseous dunes in the vicinity of a large gold mine in the eastern Goldfields. Tecticornia laevigata K.A.Sheph., is closely allied to T. mellaria but has a widespread distribution and is not considered to be under threat. Images are included along with distribution maps and an amended “Flora of Australia” key to the former genus Halosarcia Paul G.Wilson.
Tecticornia indefessa (Chenopodiaceae: Salicornioideae), a new mat samphire (formerly Tegicornia) from north of Esperance, Western Australia
SHEPHERD, K.A., Nuytsia 17: 367–374 (2007)
A taxon previously thought to be an intergeneric hybrid between an unknown species of the former genus Halosarcia Paul G.Wilson (now Tecticornia Hook.f.) and Tegicornia uniflora Paul G.Wilson (now Tecticornia uniflora (Paul G.Wilson) K.A.Sheph. & Paul G.Wilson) is recognised as a distinct species: Tecticornia indefessa K.A.Sheph. While sharing a similar mat-like habit and perianth structure to the dioecious T. uniflora, this taxon has bisexual or female flowers with distinctive seeds. Previous analysis of nuclear DNA sequences supports this taxon as distinct. Illustrations and maps and a revised description of T. uniflora are included.
Two new Western Australian species of Dodonaea (Sapindaceae) from northern Yilgarn ironstones
SHEPHERD, K.A., RYE, B.L., MEISSNER, R.A. AND WEST, J.G., Nuytsia 17: 375–384 (2007)

Both species have conservation priority. A distribution map and photographs of the new species are presented along with amendments to the relevant part of the “Flora of Australia” key to species of Dodonaea.
Kunzea acicularis, K. strigosa and K. similis subsp. mediterranea (Myrtaceae) - new taxa from near Ravensthorpe, Western Australia
TOELKEN, H.R. AND CRAIG, G.F, Nuytsia 17: 385–396 (2007)
A re-assessment of additional material in the Kunzea preissiana Schauer and K. similis Toelken complexes resulted in two new species and a subspecies being described: K. acicularis Toelken & G.F.Craig, K. strigosa Toelken & G.F.Craig and K. similis subsp. mediterranea Toelken & G.F.Craig. A revised key to Kunzea Rchb. subsect. Floridae Toelken, a table of characters for critical species in the K. preissiana complex, and detailed discussions are provided.
Lobelia cleistogamoides (Campanulaceae, subfamily Lobelioideae, Lobelia sect. Holopogon), a new species related to L. heterophylla from Western Australia and South Australia

Lobelia cleistogamoides N.G.Walsh & Albr., a member of the L. heterophylla Labill. complex, is described. The new species is known to occur from near Mullewa to just east of Esperance in Western Australia, with a disjunct occurrence on the Eyre Peninsula in South Australia. It differs from L. heterophylla s. str. principally in its much smaller flowers and has been known previously as Lobelia sp. small flowers (K.F. Kenneally 7705). Current collection information precludes an accurate assessment of its conservation status.
Allocasuarina hystricosa (Casuarinaceae): a new species from south-west Western Australia, with notes on related species
WEGE, J.A., Nuytsia 17: 403–414 (2007)
Allocasuarina hystricosa Wege is described as new. Known largely from the Ravensthorpe region, this dioecious species is characterised by erect branchlets with 10–12 leaf teeth per whorl, long articles (mostly 15–35 mm long), and three (more rarely two or up to five) spines per cone bracteole protuberance. Revised descriptions are provided for the phylogenetically related species A. scleroclada (L.A.S.Johnson) L.A.S.Johnson, A. corniculata (F.Muell.) L.A.S.Johnson, A. spinosissima (C.A.Gardner) L.A.S.Johnson, A. globosa L.A.S.Johnson and A. tortiramula E.M.Benn., and a lectotype chosen for A. tortiramula. A putative new taxon, A. spinosissima subsp. short spine (D.L. Serventy & A.R. Main s.n. 25/8/1960), is highlighted for further research. The recent acquisition by the Western Australian Herbarium of a significant number of Allocasuarina specimens of Western Australian origin is noted.

Stylidium amabile Wege & Coates, a new, rare triggerplant from near Maya in south-west Western Australia, is described and illustrated. This new species has morphological affinity to the rare Wongan Hills triggerplant S. coroniforme F.L.Erickson & J.H.Willis, but has a distinct stigma, a different pattern of corolla markings and is genetically distinct. A revised description of S. coroniforme is provided and S. coroniforme subsp. amblyphyllum Wege, a new infraspecific taxon with distinctive leaves and a distribution near Quairading, is recognised. These three taxa are among the most geographically restricted within the triggerplant genus and all are vulnerable to local extinction.
Two new triggerplants (Stylidium; Stylidiaceae) from the eastern margin of the Swan Coastal Plain, Western Australia
WEGE, J.A., KEIGHERY, G.J. AND KEIGHERY, B.J., Nuytsia 17: 445–452 (2007)
Stylidium ferricola Wege & Keighery and S. korijekup Wege, B.J.Keighery & Keighery are newly described. Stylidium ferricola is endemic to the southern ironstones near Busselton and is distinctive in the genus on account of its compact, rosetted habit, narrowly-oblanceolate leaves with entire margins and a hair-like mucro, paniculate inflorescences, oblong to cylindrical hypanthia bearing glandular trichomes, and vertically-paired corolla lobes. Stylidium korijekup is known from a single population occurring on laterite soils near Harvey and is characterised by a cormaceous habit, petiolate leaves, glabrous scapes bearing scattered sterile bracts, paniculate inflorescences, glabrous hypanthia and calyces, creamy-yellow and laterally-paired corolla lobes, and six, oblong, red-tipped throat appendages.

Rediscovery of Tetratheca nuda var. spartea (Elaeocarpaceae) in south-west Western Australia and elevation to specific rank as Tetratheca spartea
BUTCHER, R., Nuytsia 18: 39–47 (2008)
Tetratheca nuda Lindl. var. spartea Planch. ex Benth. was named by Bentham in 1863 from material collected from an unspecified locality by Drummond in 1843. Mueller placed the name in synonymy under T. virgata Steetz in 1882, but Thompson recognised and lectotypified the name in 1976, reiterating the close affinity with T. nuda but querying the status of the taxon. The taxon was known only from the type material until a 2005 collection from near Toodyay was confirmed as comparable with the type. Additional collections have since confirmed its distinctness from T. nuda. This taxon is described in full herein as T. spartea (Benth.) R.Butcher. Images of the new species and a distribution map are provided, as is an amended taxonomic key to the species of ‘leafless’ Tetratheca in Western Australia.

(1870) and later placed in synonymy under var. sphaerocarpa has recently been rediscovered and is again recognised as an accepted taxon.
Three new species of Leucopogon (Ericaceae: Styphelioideae: Styphelieae) from the far south-west of Western Australia
HISLOP, M., Nuytsia 18: 61–78 (2008)
Two new species, Leucopogon altissimus Hislop and L. wheelerae Hislop, are described. A third taxon, L. richei (Labill.) R.Br. var. acutifolius Benth., is elevated to species level under a new name, L. interstans Hislop, and with an expanded circumscription. All three are illustrated and their distributions mapped. Full descriptions of the species L. alternifolius R.Br. and L. australis R.Br., which are morphologically similar to L. wheelerae and L. interstans respectively, are given for purposes of comparison. Lectotypes are designated for the following taxa: L. alternifolius R.Br., L. australis R.Br., L. interruptus R.Br., L. paniculatus Sond., L. polystachyus R.Br. and L. polystachyus var. serratifolius Sond.

A review of Acacia coolgardiensis (Leguminosae: Mimosoideae) and closely related species in Western Australia
MASLIN, B.R. AND BUSCUMB, C., Nuytsia 18: 107–125 (2008)
The three subspecies formerly comprising the widespread, variable, Western Australian species Acacia coolgardiensis Maiden are now treated as distinct species, namely, A. coolgardiensis, A. effusifolia Maslin & Buscumb (syn. A. coolgardiensis subsp. effusa R.S.Cowan & Maslin) and A. latior (R.S.Cowan & Maslin) Maslin & Buscumb (syn. A. coolgardiensis subsp. latior R.S.Cowan & Maslin). Two new related species are also described, A. incognita Maslin & Buscumb which was formerly confounded with A. coolgardiensis subsp. coolgardiensis, and the recently discovered A. sulcaticaulis Maslin & Buscumb which is listed as a Priority One species according to the Department of Environment and Conservation’s (DEC) Conservation Codes for Western Australian Flora. A key to the recognition of these five species is presented.
Acacia diallaga (Leguminosae: Mimosoideae), a new geographically restricted species with diallagous phyllodes from the Midwest Region of south-west Western Australia
MASLIN, B.R. AND BUSCUMB, C., Nuytsia 18: 127–132 (2008)
Acacia diallaga Maslin & Buscumb, a new species of Acacia sect.Juliflorae (Benth.) C.Moore & Betche restricted to a small area east of Morawa in the Midwest Region of Western Australia is described. A feature of the new species (and one from which the botanical name is derived) is that during times of drought the phyllodes turn a purplish colour, reverting to their normal glaucous to sub-glaucous colour when conditions improve. This process of foliage colour change related to weather conditions occurs also in A. subsessilis A.R.Chapman & Maslin which is the closest relative of A. diallaga. The new species is listed as a Priority Two species according to the Department of Environment and Conservation’s Conservation Codes for Western Australian Flora.
Acacia umbraculiformis (Leguminosae: Mimosoideae), a new species related to A. quadrimarginea from the Midwest Region of south-west Western Australia
MASLIN, B.R. AND BUSCUMB, C., Nuytsia 18: 133–138 (2008)
A new species common in the Midwest Region of Western Australia, Acacia umbraculiformis Maslin & Buscumb, is described and assigned to Acacia sect. Juliflorae (Benth.) C.Moore & Betche. Until recently this species had been confounded with A. quadrimarginea F.Muell.
New taxa of Acacia (Leguminosae: Mimosoideae) and notes on other species from the Pilbara and adjacent desert regions of Western Australia
MASLIN, B.R. AND VAN LEEUWEN, S., Nuytsia 18: 139–188 (2008)
Preparatory to publishing books on the Acacia Mill. flora of the Pilbara region, 10 new species (A. bromilowiana Maslin, A. fecunda Maslin, A. leeuweniana Maslin, A. minutissima Maslin, A. subcontorta Maslin, A. subtiliformis Maslin, A. trudgeniana Maslin, A. robeorum Maslin, A. thoma Maslin and A. walkeri Maslin) and two new subspecies (A. catenulata C.T.White subsp. occidentalis Maslin and A. steedmanii Maiden & Blakely subsp. borealis Maslin) are described. Acacia coriacea DC. is now more narrowly circumscribed to include subsp. coriacea and subsp. pendens R.S.Cowan & Maslin only, while the former A. coriacea subsp. sericophylla (F.Muell.) R.S.Cowan & Maslin has been reinstated as a distinct species (A. sericophylla F. Muell.). Notes on the variation in Western Australian plants of A. drepanocarpa F.Muell. are provided. Acacia bromilowiana, A. fecunda and A. subtiliformis are Priority Three taxa and A. leeuweniana is a Priority One taxon according to the Department of Environment and Conservation’s Conservation Codes for the Western Australian Flora.
An updated diagnosis for Eucalyptus series Accedentes (Myrtaceae) and a new mallee species for the series occurring in far western Australia
NICOLLE, D. AND BROOKER, M.I.H., Nuytsia 18: 189–196 (2008)
Eucalyptus L'Hér. ser. Accedentes Chippend. is diagnosed by an exclusive combination of characters for the first time. The series consists of nine species, all but one of which are endemic to Western Australia, including the newly described Eucalyptus baiophylla D.Nicolle & Brooker, a mallee occurring between Exmouth and Carnarvon on the west coast of Australia. The new species was formerly included in E. prominens Brooker and is most closely related to E. zopherophloia Brooker & Hopper. A key to the series is included and a map and illustrations of the new species are provided.
A revision of Eucalyptus ser. Cornutae subser. Conjunctae (Myrtaceae) from the south coast of Western Australia, including the description of four new taxa and comments on the hybrid origin of E. bennettiae
NICOLLE, D., FRENCH, M.E. AND MCQUOID, N.K., Nuytsia 18: 197–222 (2008)
Eight terminal taxa are recognised in Eucalyptus L’Hér. ser. Cornutae (Benth.) Brooker subser. Conjunctae Brooker. Two new species are described, viz., E. sinuosa D.Nicolle, M.E.French & McQuoid, known from only a few populations in the Corackerup Creek area and in Fitzgerald River National Park, and E. retusa D.Nicolle, M.E.French & McQuoid, known from one or possibly two populations from near Bremer Bay. New subspecies described are E. lehmannii (Schauer) Benth. subsp. parallela D.Nicolle & M.E.French, which is the widespread variant of the species, occurring from the Stirling Range area eastwards to Cape Arid, and E. conferruminata D.Carr & S.Carr subsp. recherche D.Nicolle & M.E.French, the eastern variant of that species apparently endemic to the Recherche Archipelago and the common variant in cultivation across southern Australia. The distribution of E. arborella Brooker & Hopper is modified with the discovery of a new population and the exclusion of another population included in this species by others. The hybrid status of E. bennettiae D.Carr & S.Carr is discussed. A key to E. subser. Conjunctae is provided.
Recognition of new taxa in Grevillea (Proteaceae: Grevilleoideae) from south-west Western Australia
OLDE, PETER M. AND MARRIOTT, NEIL R., Nuytsia 18: 223–234 (2008)
In this paper we recognise one new Grevillea species, Grevillea hislopii P.M.Olde & N.R.Marriott and two new subspecies, Grevillea althoferorum P.M.Olde & N.R.Marriott subsp. fragilis P.M.Olde & N.R.Marriott and Grevillea bracteosa C.F.Meisn. subsp. howatharra P.M.Olde & N.R.Marriott. All taxa occur in south-west Western Australia. Morphological analysis suggests that the taxa are not closely related. Interspecific and intraspecific keys are provided and affinities are discussed where relevant. Some of the taxa have a conservation priority and Conservation Codes are provided in all cases.
Seorsus, a new Gondwanan genus of Myrtaceae with a disjunct distribution in Borneo and Australia
RYE, B.L. AND TRUDGEN, MALCOLM E., Nuytsia 18: 235–257 (2008)
The new genus Seorsus Rye & Trudgen (Myrtaceae tribe Chamelaucieae) has four species, two in Borneo and one each in the north of the Northern Territory and the south-west of Western Australia. Seorsus is distinguished from related genera by the shape of its anther connective, the orientation of its anther loculi and its distinctly facetted seeds. Two of its four species were previously placed in Astartea DC., a third in Baeckea L. and the fourth is the new species Seorsus aequatorius Rye & Trudgen. Three new combinations, S. clavifolius (C.A.Gardner) Rye & Trudgen, S. intratropicus (F.Muell.) Rye & Trudgen and S. taxifolius (Merr.) Rye & Trudgen, are made. The morphological characteristics, Gondwanan distribution and relationships of the new genus are discussed. Descriptions, keys, illustrations and distribution maps are provided.
Tecticornia papillata (Chenopodiaceae: Salicornioideae), a new andromonoecious samphire from near the Carnarvon Range, Western Australia
SHEPHERD, K.A., Nuytsia 18: 259–266 (2008)
Tecticornia papillata K.A.Sheph., described here as new, has an unusual fruit structure previously only observed in T. disarticulata (Paul G.Wilson) K.A.Sheph. & Paul G.Wilson. It differs from this species in having vegetative articles and bracts with strongly fimbriate margins and caudate apices, and a distinctly papillate epidermis for which the species is named. As this new species has a restricted distribution it has a Priority One conservation status. A distribution map and images of the species are presented. In addition, the molecular and morphological diversity within T. disarticulata is discussed.
New combinations in the genus Dysphania (Chenopodiaceae)
SHEPHERD, K.A. AND WILSON, PAUL G., Nuytsia 18: 267–272 (2008)
A long standing recognition of a possible affinity between Dysphania R.Br. and Chenopodium L. subg. Ambrosia A.J.Scott has been corroborated by molecular phylogenetic evidence. While the North American species of C. subg. Ambrosia have been transferred to Dysphania this has not occurred elsewhere. In light of this, new combinations are made here for the Australian and New Zealand species of C. subg. Ambrosia. A key to the Australian species of Dysphania is provided.
Pilostyles coccoidea (Apodanthaceae), a new species from Western Australia described from morphological and molecular evidence
THIELE, K.R., WYLIE, S.J., MACCARONE, L. AND HOLLICK, P., Nuytsia 18: 273–284 (2008)
Pilostyles coccoidea K.R.Thiele, a new species of holoparasitic flowering plant found on the legume genus Jacksonia R.Br. ex Sm., is described and illustrated. The new species is related to P. collina Dell and P. hamiltonii C.A.Gardner, both also from south-western Western Australia but growing on different hosts. The three species differ in morphological features of flowers and fruits. In addition, analysis of nad1, 16S and matR gene sequences confirms the distinctness of P. coccoidea from P. hamiltonii. Pilostyles coccoidea appears to be a relatively common species within its restricted range of distribution between Eneabba and the Moore River, north of Perth.
Stylidium perplexum (Stylidiaceae): a remarkable new triggerplant from south-west Western Australia
WEGE, J.A., Nuytsia 18: 285–289 (2008)

This distinctive triggerplant has a tuberous, multi-stemmed and somewhat shrubby habit, discoid glandular trichomes restricted to the pedicels and hypanthia, linear leaves to 2 cm long, an elliptic hypanthium, narrow calyx lobes, and white to purplish laterally-paired corolla lobes bearing eight purple-tipped throat appendages. It occurs within a Conservation Park south-east of Dardanup and is listed as having conservation priority in Western Australia.
A new subspecies of Gnaphalium indutum (Asteraceae: Gnaphalieae)
WILSON, PAUL G., Nuytsia 18: 291–293 (2008)
Gnaphalium indutum Hook.f. is considered to consist of two infraspecific taxa, subsp. indutum and subsp. acuminatum Paul G.Wilson subsp. nov. The latter is predominantly an inland taxon of non-saline habitats.
Coronidium, a new Australian genus in the Gnaphalieae (Asteraceae)
WILSON, PAUL G., Nuytsia 18: 295–329 (2008)
The genus Coronidium Paul G.Wilson, a segregate of Helichrysum Mill. sensu lato, is described. It consists of 17 species, all of which are found in eastern Australia while two are also present in South Australia and one in Tasmania. Six species and two subspecies are described as new: C. cymosum Paul G.Wilson, C. elatum (A.Cunn. ex DC.) Paul G.Wilson subsp. minus Paul G.Wilson, C. elatum subsp. vellerosum Paul G.Wilson, C. flavum Paul G.Wilson, C. fulvidum Paul G.Wilson, C. lanosum Paul G.Wilson, C. kaputaricum Paul G.Wilson, and C. telfordii Paul G.Wilson, while Helichrysum adenophorum var. waddelliae J.H.Willis is raised to species rank as C. waddelliae (J.H.Willis) Paul G.Wilson; a further ten species are transfers from Helichrysum: C. oxylepis (F.Muell.) Paul G.Wilson, C. rupicola (DC.) Paul G.Wilson, C. glutinosum (Hook.) Paul G.Wilson, C. lanuginosum (A.Cunn. ex DC.) Paul G.Wilson, C. newcastlianum (Domin) Paul G.Wilson, C. boormanii (Maiden & Betche) Paul G.Wilson, C. elatum (DC.) Paul G.Wilson, C. lindsayanum (Domin) Paul G.Wilson, C. adenophorum (F.Muell.) Paul G Wilson, and C. scorpioides (Labill.) Paul G.Wilson. Several names are lectotypified.
Notes on the genus _Chrysocephalum (_Angianthinae: Asteraceae) with the description of one new species from Western Australia, and a new combination
WILSON, PAUL G., Nuytsia 18: 331–338 (2008)
The probability of the genus Chrysocephalum being paraphyletic is reviewed. Helichrysum gilesii F.Muell. is transferred to Chrysocephalum. A new species from the Gibson Desert, Western Australia is described and is compared with its close relative C. gilesii (F.Muell.) Paul G.Wilson. A widespread taxon from southern Australia which has been variously referred to as Chrysocephalum apiculatum (Labill.) Steetz or C. aff. apiculatum is shown to be C. vitellinum Sond.; this name is lectotypified. A key to the species of Chrysocephalum found in Western Australia is provided.
Lepidosperma amansiferrum is an orthographic error of L. amantiferrum
BARRETT, R.L., Nuytsia 18: 339 (2008)
The name Lepidosperma amansiferrum R.L.Barrett was recently published for a new species restricted to banded ironstone formations in the southern Goldfields of Western Australia (Barrett 2007). Karen Wilson and Peter Wilson (both Royal Botanic Gardens Sydney) recently drew my attention to an error in the way the Latin words were combined to form this name. Constructed from the Latin words amans (loving) and ferrum (iron), the word amans, when combined with ferrum, should be declined to amanti- (Stearn 1992).
Kennedia lateritia, a new name for Kennedia macrophylla (Fabaceae)
LALLY, T.R. AND WILSON, PAUL G., Nuytsia 18: 340–341 (2008)
The plant currently referred to as Kennedia macrophylla (Meisn.) Benth. is a twining or scrambling shrub with a very restricted distribution in the far south-west of Western Australia. It is listed as Declared Rare Flora under the Western Australian Wildlife Conservation Act 1950 and is endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (DEWHA 2007). In contrast to its rarity in nature, this taxon is widely cultivated in temperate Australia (Jones & Gray 1977; Elliot & Jones 1993). In view of the horticultural and conservation significance of this species, a necessary change to its nomenclature is presented here in advance of a revision of the subtribe Kennediinae currently in preparation by the first author.
Calytrix gomphrenoides (Myrtaceae), a new species from the Kimberley Region of Western Australia
BARRETT, M.D., CRAVEN, L.A. AND BARRETT, R.L., Nuytsia 19 (1): 1–8 (2009)
Calytrix gomphrenoides M.D.Barrett & Craven is described as a new species from sandstone pavements of the north-west Kimberley Region of Western Australia. It is apparently most closely related to C. inopinata Craven in the C. exstipulata DC. alliance. Emendations to a published key and notes on related species are provided.

NICOLLE, D. AND FRENCH, M.E., Nuytsia 19 (1): 99–105 (2009)
A new subspecies of Eucalyptus calycogona Turcz.is described, differing from the other three subspecies of E. calycogona by the waxy branchlets, buds and fruits, the generally broader, dull adult leaves which are bluish at least when new, the consistently elliptical to ovate seedling leaves, and the generally larger flower buds and fruits. The new ubspecies is distributed on the eastern edge of the central wheatbelt in Western Australia, to the north-west of the distribution of subsp. calycogona. A key to E. ser_. Heterostemones_ Benth., a map indicating the distribution of E. calycogona in Western Australia, and illustration of the holotype and habit of E. calycogona subsp. miracula D.Nicolle & M.E.French are included.
A conspectus of the genus Amaranthus (Amaranthaceae) in Australia
PALMER, J., Nuytsia 19 (1): 107–128 (2009)
A synopsis of the 26 Amaranthus species known to occur in Australia is presented. Amaranthus centralis J.Palmer & Mowatt and A. induratus C.A.Gardner ex J.Palmer & Mowatt are described as new; distribution maps and photographs of the type specimens are included for these new species. Amaranthus undulatus R.Br. is the earliest correct name for the taxon currently known as A. pallidiflorus F.Muell., and lectotypes are selected for A. clementii Domin, A. leptostachyus Benth., A. macrocarpus Benth. and A. mitchellii Benth. A key to all species in Australia is presented.
A reduced circumscription of Balaustion and description of the new genus Cheyniana (Myrtaceae: Chamelaucieae)
RYE, B.L., Nuytsia 19 (1): 129–148 (2009)
The myrtaceous genus Balaustion Hook. is reduced to its original monotypic circumscription. Balaustion s. str. is closely related to Tilophloia Trudgen & Rye ms., both genera having stamens in a single circular series, broad filaments, a very large placenta and seeds with a large concave hilum, but Balaustion is distinguished by its prostrate habit with adventitious roots, basifixed anthers and long tubular flowers adapted to pollination by birds. A second bird-pollinated species with elongated flowers, previously known as B. microphyllum C.A.Gardner, is transferred into the new genus Cheyniana Rye as C. microphylla (C.A.Gardner) Rye. Since the type material of this species is missing, it is lectotypified on the original illustration. Another large-flowered species, but with more spreading, apparently insect-pollinated flowers, is described as C. rhodella Rye & Trudgen. Cheyniana is related to also Oxymyrrhine Schauer, which it resembles in its very reduced anthers and narrow filaments, but differs in its large colourful petals and woody indehiscent fruit. Both of the small genera treated in this taxonomic revision belong to the tribe Chamelaucieae and are restricted to the south-west of Western Australia.
Reinstatement of the Western Australian genus Oxymyrrhine (Myrtaceae: Chamelaucieae) with three new species
RYE, B.L., Nuytsia 19 (1): 149–165 (2009)
The south-western Australian genus Oxymyrrhine Schauer is reinstated and the type species, previously known as Baeckea polyandra F. Muell., is restored to its earlier name of O. gracilis Schauer.A lectotype is selected for B. polyandra and three new species, Oxymyrrhine cordata Rye & Trudgen, O. coronata Rye & ; Trudgen and O. plicata Rye & Trudgen_,_ are described. These four species make up a group described here as Oxymyrrhine s. str. and are distinguished from other members of Oxymyrrhine s. lat. and from all other genera of tribe Chamelaucieae by the broad cavity in the summit of their fruit. Oxymyrrhine s. lat. includes a particularly difficult species complex, which will be revised at a later time.
Three new species of Tecticornia (Chenopodiaceae, subfamily Salicornioideae) identified through Salinity Action Plan surveys of the wheatbelt region, Western Australia
SHEPHERD, K.A. AND LYONS, M.N., Nuytsia 19 (1): 167–180 (2009)
A number of potentially new species have been discovered through ongoing Government surveys of the wheatbelt region of Western Australia. Three new samphires identified from collections made in saline areas during these surveys are described here: Tecticornia annelida K.A.Sheph. & M.Lyons, T. sparagosa K.A.Sheph. & M.Lyons and T. loriae K.A. Sheph. & M.Lyons. Distribution maps and illustrations of these new species are included.
Guichenotia anota and Guichenotia apetala (Lasiopetaleae: Byttneriaceae or Malvaceae s. lat.) a new and a revised species endemic to the Ravensthorpe Range, south-west Western Australia
WILKINS, C.F. AND WHITLOCK, B.A., Nuytsia 19 (1): 181–190 (2009)
Guichenotia anota C.F.Wilkins is described as new and Guichenotia apetala A.S.George is revised. Both are endemic to the Ravensthorpe Range in south-west Western Australia. Cladistic analyses of morphological characters, and chloroplast and nuclear DNA sequences (Wilkins & Whitlock in prep.) show these two species to be most closely related to each other, and more closely related to Lasiopetalum Sm. than to Guichenotia J. Gay. As both are priority species for conservation, in an area with developmental pressures from mining, they require urgent description and revision, and are included here in the latter genus until their generic placement is certain. Anatomical leaf data is presented.
A new species of Pultenaea (Mirbelieae: Fabaceae) from Kundip, Western Australia
WILKINS, C.F., ORTHIA, L.A. AND CRISP, M.D., Nuytsia 19 (1): 191–196 (2009)
A new species Pultenaea craigiana C.F.Wilkins, Orthia & Crisp is described. It has affinity to P. brachytropis Benth. This species is endemic to the south-west of Western Australia and is a priority species for conservation. Conservation notes and a distribution map are provided.
Recombination of subspecies in Trihaloragis (Haloragaceae)
MOODY, M.L., Nuytsia 19 (1): 197 (2009)
Moody and Les (2007) recognized the genus Trihaloragis consisting of the single species Trihaloragis hexandra (F.Muell.) M.L.Moody & D.H.Les. Recombination of the three subspecies of Haloragis hexandra was overlooked at the time. Here new combinations of the three subspecies are presented.
Clarification of recent combinations in the genus Dysphania (Chenopodiaceae)
SHEPHERD, K.A. AND WILSON, PAUL G., Nuytsia 19 (1): 198–199 (2009)
In a paper commenting on the generic status of the Chenopodiaceae, Wilson (1987) noted an affinity between the representatives of Chenopodium L. subg. Ambrosia A.J.Scott and the genus Dysphania R.Br., based on the presence of both septate and glandular hairs as well as similarities in leaf shape, leaf venation, inflorescence structure and seed orientation. Mosyakin and Clemants (2002) later came to a similar conclusion and reassigned the North American representatives (both endemic and naturalised) of Chenopodium subg. Ambrosia to Dysphania.
Lectotypification of ten Restionaceae species names from south-west Western Australia
BARRETT, R.L. AND BRIGGS, B.G., Nuytsia 19 (2): 203–209 (2009)
A lectotype is selected for ten names published in 1993 and 1996 by K. Dixon, K.A. Meney and J. Pate for species of Restionaceae in the genera Desmocladus Nees, Harperia W.Fitzg., Hypolaena R.Br., Lepidobolus Nees, Loxocarya R.Br., Onychosepalum Steud., Leptocarpus R.Br. and Restio Rottb. The relevant species originally named in Leptocarpus and Restio are now included in Meeboldina Suess. and Chordifex B.G.Briggs & L.A.S.Johnson respectively. Additional collections of the ten taxa involved are also cited.
New taxa in the Leucopogon gracilis group (Ericaceae: Styphelioideae: Styphelieae)
HISLOP, M., Nuytsia 19 (2): 211–228 (2009)
Three new taxa, Leucopogon paradoxus Hislop, L. tenuicaulis Hislop and L. elegans Sond. subsp. psorophyllus are described. The first two of these are illustrated and the distributions of all three are mapped. A key is provided for all Western Australian taxa currently referred to the informal, subgeneric Leucopogon gracilis Group (sensu Hislop & Chapman 2007). Lectotypes are designated for the following taxa: Leucopogon elegans Sond., L. gracilis R.Br., L. oppositifolius Sond. and L. oppositifolius var. pubescens Sond.
Grevillea tetragonoloba (Proteaceae: Grevilleoideae) recircumscribed, with notes on its typification and a new segregate species, Grevillea nivea, described
OLDE, PETER M. AND MARRIOTT, NEIL R., Nuytsia 19 (2): 229–243 (2009)
Grevillea nivea P.M.Olde & N.R.Marriott is the third species that we have segregated and described from Grevillea tetragonoloba Meisner sensu McGillivray. The type citation of Grevillea tetragonoloba is discussed and modified. Recognition of Grevillea nivea as distinct from Grevillea tetragonoloba requires a modified circumscription for the latter species, and a full, updated description is provided here. A key is provided enabling distinction from closely related species.
A new subspecies of Acacia pentadenia (Leguminosae: Mimosoideae) from south-western Australia
REID, J.E., WARDELL-JOHNSON, G. AND MASLIN, B.R., Nuytsia 19 (2): 245–252 (2009)
A previously recognised informal variant of Acacia pentadenia Lindl. is described following extensive field and herbarium studies focused on the forest region to the north-east of Walpole. The new subspecies, Acacia pentadenia subsp. syntoma, is most readily distinguished from subsp. pentadenia by a combination of morphological attributes, as well as habit , phenological and ecological differences. Field observations have shown the two subspecies to be occasionally sympatric. A key to the subspecies is provided together with a distribution map and comparative images.
A new species of Hakea (Proteaceae) from the Swan Coastal Plain, Western Australia
SHEPHERD, K.A. AND BARKER, R.M., Nuytsia 19 (2): 253–258 (2009)
Hakea oligoneura K.A.Sheph. & R.M.Barker,a new species described herein, is only known from a few populations less than 100 km from the Perth metropolitan area. A distribution map and images of this new species are included.
Thysanotus unicupensis (Laxmanniaceae), a new species discovered in Unicup Nature Reserve, south-west Western Australia
SIRISENA, U.M., MACFARLANE, T.D. AND CONRAN, J.G., Nuytsia 19 (2): 259–263 (2009)
Thysanotus unicupensis is described as a new species from south-west Western Australia. This species shows some affinities to T. chinensis, T. formosus and T.parviflorus and is apparently localised on lateritic soils in moderately sunny areas within Jarrah/ Marri (Eucalyptus marginata/Corymbia calophylla) woodlands. The key published in Flora of Australia (1987) is amended to include the new species.
A new circumscription for Lysinema ciliatum (Ericaceae: Styphelioideae: Epacrideae) and reinstatement of L. pentapetalum
THIELE, K.R., Nuytsia 19 (2): 265–275 (2009)
Lysinema ciliatum has long been regarded as a widespread and variable species. Occurring throughout much of the South-West Botanical Province of Western Australia on a variety of substrates, it is morphologically variable in foliar and floral characters, with up to eleven morphotypes informally recognised as putatively distinct taxa following a preliminary assessment in the early 1990s. Examination of material from throughout the species’ range shows that most of the currently recognised informal morphotypes comprise a single, variable species which cannot be adequately divided into taxa. A second, distinct species is restricted to the south coast of Western Australia, approximately between Albany and Esperance, with a disjunct outlier east of Perth. Comparison with types shows that the correct name for the widespread taxon is Lysinema pentapetalum R.Br., while the mostly southern-coastal taxon matches the type of L. ciliatum. Descriptions and distribution maps are provided for these taxa, and a key to all species of Lysinema provided.
Banksia recurvistylis (Proteaceae), a new species from Western Australia
THIELE, K.R., Nuytsia 19 (2): 277–281 (2009)
Banksia recurvistylis K.R.Thiele is described to accommodate anomalous populations previously referred to B. meganotia (A.S.George) A.R.Mast & K.R.Thiele. The new species differs from B. meganotia in its habit and flower and leaf dimensions, and is geographically disjunct. Both B. meganotia and B. recurvistylis have relatively restricted distributions and are of conservation significance.
Three new species of Hibbertia (Dilleniaceae) from Western Australia
THIELE, K.R., Nuytsia 19 (2): 283–293 (2009)
Three new species, Hibbertia leucocrossa K.R.Thiele, H. fasciculiflora K.R.Thiele and H. propinqua K.R.Thiele are described as new. All taxa occur north of Perth in the Lesueur Sandplains subregion of the Geraldton Sandplains bioregion in the South West Botanical Province, Western Australia. A revision of a key to the Hibbertia species of Western Australia is provided.
A new, rare Marianthus (Pittosporaceae) from the Bremer Range in Western Australia
WEGE, J.A. AND GIBSON, N., Nuytsia 19 (2): 295–302 (2009)
Marianthus aquilonaris N.Gibson & Wege, a new species allied to M. mollis (E.M.Benn.) L.Cayzer & Crisp, is described. Morphometric analysis shows that it is most readily differentiated from M. mollis by its higher leaf L:W ratio, higher petal L:W ratio and longer petioles. Other distinguishing features include a more erect habit, smooth and more or less glabrous leaves with attenuate rather than rounded bases , fewer pilose hairs on the stems, peduncles and fruit, and paler petals. Descriptions of both taxa are provided and include the first record of glandular trichomes for the genus. Marianthus aquilonaris is endemic to the Bremer Range and potentially threatened by mining-related activities. It is gazetted as Declared Rare Flora in Western Australia under the name M. sp. Bremer (N. Gibson & M. Lyons 1776).
Two new species of Hibbertia (Dilleniaceae) from near Ravensthorpe in Western Australia
WEGE, J.A. AND THIELE, K.R., Nuytsia 19 (2): 303–310 (2009)
Two new and geographically restricted species allied to H. hamulosa J.R.Wheeler and H. mucronata (Turcz.) Benth. are newly described. Hibbertia abyssa Wege & K.R.Thiele is distinctive for its long, slender and more or less glabrous peduncles, and sepals with both uncinate and minute stellate hairs on the outer surface. This species, which occurs on shallow soils with siltstone outcropping, is known from a single population adjacent to the nickel mine on Bandalup Hill and has recently been gazetted as Declared Rare Flora. Hibbertia atrichosepala Wege & K.R.Thiele is readily distinguished from allied species by its completely glabrous sepals. It is a narrow range endemic of rocky, lateritic habitats in in the Ravensthorpe Range and is listed as having Priority One conservation status.
Ptilotus luteolus, a new combination in Ptilotus (Amaranthaceae)
DAVIS, R.W., Nuytsia 19 (2): 311–312 (2009)
Benl has been the most prominent recent author on the genus Ptilotus R.Br., and described a number of infraspecific taxa from a small amount of material. Many new collections have now been made and it has become apparent that the ranking of these taxa is in need of review. After infraspecific taxa in Ptilotus astrolasius F.Muell. were examined it became apparent that Ptilotus astrolasius var. luteolus Benl & H.Eichler warrants the rank of species.
An interim key to the Western Australian tribes and genera of Myrtaceae
RYE, B.L., Nuytsia 19 (2): 313–323 (2009)
As an interim measure to permit identification of Western Australian genera, a status quo key is presented here. At the same time the opportunity is taken to key out the ten tribes represented in Western Australia.
Typification of Gnaphalium collinum var. monocephalum (Gnaphalieae: Asteraceae) and clarification of related material
FLANN, C., WILSON, PAUL G. AND WIERENGA, J.J., Nuytsia 20: 1–5 (2010)
The protologue of Gnaphalium collinum var. monocephalum Hook.f. cites three gatherings which are now considered to be referable to three different taxa known by the names Euchiton lateralis (C.J.Webb) Breitw. & J.M.Ward, Euchiton traversii (Hook.f.) Holub and Argyrotegium mackayi (Buchanan) J.M.Ward & Breitw. This has caused confusion regarding the typification and application of J.D.Hooker’s varietal name. This article resolves the uncertainty and provides a corrected synonymy for all the taxa involved.
Molecular markers provide an independent test of species boundaries in the two morphologically similar species Desmocladus flexuosus and D. asper (Restionaceae)
SINCLAIR, E.A. AND BARRETT, R.L., Nuytsia 20: 7–17 (2010)
Desmocladus flexuosus exhibits extensive morphological variation across its geographic range, and even within the Perth metropolitan area. It may be potentially confused with its congener, D. asper, across this region where the two are sympatric. Here we use molecular markers to show that these two species are genetically distinct, and describe several morphological characters that can aid identification in the field.
A new locally endemic species of Acrotriche (Ericaceae: Styphelioideae: Styphelieae) from the Ravensthorpe area
HISLOP, M., Nuytsia 20: 19–25 (2010)
A new and apparently rare species of Acrotriche R.Br., A. orbicularis Hislop, is described, illustrated and its distribution mapped. For purposes of comparison, the species with which it is most likely to be confused, Acrotriche cordata (Labill.) R.Br., is also illustrated and mapped. An updated key to the Acrotriche species of Western Australia is provided.
Melaleuca (Myrtaceae) of Western Australia: five new species, three new combinations, one new name and a new state record
CRAVEN, L.A., LEPSCHI, B.J. AND COWLEY, K.J., Nuytsia 20: 27–36 (2010)
Recent work has resulted in the recognition of five new species of Melaleuca from the south-west of Western Australia: M. genialis Lepschi, M. ochroma Lepschi, M. protrusa Craven & Lepschi, M. sophisma Lepschi, and M. ulicoides Craven & Lepschi. Reassessment of the taxonomic status of three previously described taxa shows that specific rank is warranted and the following three new combinations are made: M. acutifolia (Benth.) Craven & Lepschi, M. calcicola (Barlow ex Craven) Craven & Lepschi, and M. spectabilis (Barlow ex Craven) Craven & Lepschi. Melaleuca citrina Turcz.is a later homonym of M. citrina (Curtis) Dum.Cours. and the replacement name M. lutea Craven is provided. Melaleuca viminalis (Sol. ex Gaertn.) Byrnes, hitherto known only from eastern Australia has recently been collected from the Kimberley region of northern Western Australia.
A revision of the Micromyrtus racemosa complex (Myrtaceae: Chamelaucieae) of south-western Australia
RYE, B.L., Nuytsia 20: 37–56 (2010)
The Micromyrtus racemosa species complex, which is endemic to south-western Australia, is revised. The complex includes two previously named species, M. racemosa Benth. and M. trudgenii Rye. Six new taxa are described here: M. arenicola Rye, M. collina, M. greeniana, M. mucronulata, M. prochytes and M. rubricalyx. Descriptions are also given for two new taxa that are considered to be too poorly known at present to name. Also included are distribution maps and a key to all members of this complex, and an illustration of M. mucronulata by Charles Gardner.
A revision of Calothamnus quadrifidus (Myrtaceae)
GEORGE, A.S. AND GIBSON, N., Nuytsia 20: 57–77 (2010)
The highly variable species Calothamnus quadrifidus R.Br. is discussed and an infraspecific classification with eight subspecies is proposed. The following new taxa are described: Calothamnus quadrifidus subsp. petraeus A.S.George & N.Gibson, C. quadrifidus subsp. seminudus A.S.George & N.Gibson and C. quadrifidus subsp. teretifolius A.S.George & N.Gibson. New combinations are C. quadrifidus subsp. angustifolius (Ewart) A.S.George & N.Gibson, C. quadrifidus subsp. asper (Turcz.) A.S.George & N. Gibson and C. quadrifidus subsp. homalophyllus (F.Muell.) A.S. George & N.Gibson, and a new status is given for C. quadrifidus subsp. obtusus (Benth.) A.S.George & N.Gibson.
Stylidium miscellany 1: typifications and new taxa from south-west Western Australia
WEGE, J.A., Nuytsia 20: 79–108 (2010)
The types of names relating to 24 species of Stylidium from south-west Western Australia are reviewed. Lectotypes are selected for S.barleei F.Muell., S. breviscapum var. erythrocalyx Benth., S. ciliatum Lindl., S. ciliatum var. minor Sond., S. dispermum F.Muell., S. elongatum Benth., S. galioides C.A.Gardner, S. imbricatum Benth., S. lepidum F.Muell. ex Benth., S. limbatum F.Muell., S. miniatum Mildbr., S. piliferum R.Br. S. plantagineum Sond., S. preissii (Sond.) F.Muell., S. verticillatum F.Muell. and S. yilgarnense E.Pritz. Neotypes are nominated for S. pritzelianum Mildbr., S. pseudocaespitosum Mildbr. and S. stenosepalum E.Pritz. Stylidium piliferum subsp. minor (Mildbr.) Carlquist is lectotypified and placed into synonymy under S. piliferum. Stylidium elegans J.Drumm. is newly established as a synonym of S. plantagineum and a lectotype designated. Stylidium involucratum F.Muell. is reinstated and S. stowardii M.B.Scott placed into synonymy. The collector of the type of S. glaucum (Labill.) Labill. is confirmed as Leschenault de la Tour. Stylidium thesioides DC. is reinstated and S. canaliculatum Lindl., an earlier but illegitimate name, is placed into synonymy. Stylidium scandens R.Br. is lectotypified and S. nymphaeum Wege, a species collected by Robert Brown in 1801 and drawn by Ferdinand Bauer, is newly described. Stylidium spathulatum R.Br. subsp. acuminatum Carlquist is raised to species level and S. acuminatum subsp. meridionalis Wege newly described. Stylidium glaucum subsp. angustifolium Carlquist is similarly raised to species level, whilst S. luteum subsp. glaucifolium Carlquist retained as a subspecies but transferred to S. angustifolium (Carlquist) Wege.
An account of Eutaxia (Leguminosae: Mirbelieae) with a focus on the Western Australian species
WILKINS, C.F., CHAPPILL, J.A. AND HENDERSON, G.R., Nuytsia 20: 109–167 (2010)
The Western Australian species of the endemic Australian legume genus Eutaxia R.Br. are revised. Twenty two species are recognised, all but three of them confined to Western Australia. Six new species are described, E. acanthoclada G.R.Hend. & Chappill, E. inuncta C.F. Wilkins & Chappill, E. exilis C.F.Wilkins & G.R.Hend., E. hirsuta C.F.Wilkins & G.R.Hend. Pultenaea neurocalyx Turcz. is transferred to Eutaxia, P. neurocalyx var. major Benth. is given specific status as E. major (Benth.) C.F.Wilkins & Chappill, and two new subspecies are recognised, E. neurocalyx subsp. nacta C.F.Wilkins and E. neurocalyx subsp. papillosa C.F.Wilkins. Eutaxia diffusa F.Muell. is reinstated as a distinct species rather than a variety of E. microphylla and E. empetrifolia Schltdl. and E. leptophylla Turcz. are reinstated as distinct species rather than being synonymous with E. microphylla (R.Br.) C.H.Wright & Dewar. Eutaxia densifolia Turcz. and E. dillwynioides Meisn. are reduced to synonyms of E. parvifolia Benth, and Eutaxia obovata (Labill.) C.A.Gardner is correct name for the type of Eutaxia.
Two new, glaucous-leaved species of Isopogon (Proteaceae: Proteoideae: Leucadendreae) from south-western Australia
HISLOP, M. AND RYE, B.L., Nuytsia 20: 169–181 (2010)
Two new species and two new subspecies with simple, flat, glaucous leaves are described: Isopogon panduratus Hislop & Rye, I. panduratus subsp. palustris Hislop & Rye, I. pruinosus Hislop & Rye and I. pruinosus subsp. glabellus Hislop & Rye. Their distributions are mapped and the first three are illustrated. The four new taxa belong in a species group that includes Isopogon axillaris R.Br. and I. buxifolius R.Br.s. lat. Isopogon panduratus subsp. palustris has conservation priority.
Calothamnus (Myrtaceae): precursor paper to Flora of Australia
GEORGE, A.S., Nuytsia 20: 183–200 (2010)
The following new taxa are described: Calothamnus arcuatus A.S George, C. borealis subsp. cinereus A.S.George, C. cupularis A.S. George, C. montanus A.S.George, C. phellosus A. S.George (the species previously known as C.oldfieldii), C. roseus A.S.George and C. scabridus A.S.George. Calothamnus blepharospermus var. glaber Benth. is raised to specific rank. The name Calothamnus lateralis f. crassus Benth. (C. crassus (Benth.) Hawkeswood) is shown to have been misapplied by Hawkeswood and is given varietal rank under C. lateralis. Calothamnus blepharantherus (a synonym of C. sanguineus Labill.), C. blepharospermus F. Muell. and C. chrysanthereus F.Muell. are lectotypified. Calothamnus oldfieldii F.Muell. is also lectotypified and the name correctly applied, with C. kalbarriensis Hawkeswood reduced to synonymy.
A taxonomic revision of the Western Australian endemic species Kennedia coccinea (Fabaceae)
LALLY, T.R., Nuytsia 20: 201–215 (2010)
Two new subspecies are described in Kennedia coccinea; K. coccinea subsp. esotera Lally and K. coccinea subsp. calcaria Lally. Distribution maps are provided for all the subspecies, and photographs of the type specimens for the new subspecies.
Re-evaluation of Ptilotus polystachyus sens. lat. (Amaranthaceae) and creation of the new combination Ptilotus giganteus
DAVIS, R.W. AND BUTCHER, R., Nuytsia 20: 217–227 (2010)
This paper evaluated infraspecific taxa in Ptilotus polystachyus (Gaudich.) F.Muell. using morphometric analysis. We conclude that var. arthrotrichus Benl. should not be regarded as a distinct variety from var. polystachyus and that var. longistachyus (W.Fitzg.) and var. pullenii (Benl) Benl should be merged into a single taxon and elevated in rank to species. The new combination P. giganteus (Cunn. ex Moq.) R. W.Davis & R.Butcher is erected for this taxon. With these changes, P. polystachyus is now regarded as a widespread and variable species without infraspecific taxa. Revised descriptions are presented for these two species.
Enekbatus, a new Western Australian genus of Myrtaceae with a multi-locular indehiscent fruit
TRUDGEN, MALCOLM E. AND RYE, B.L., Nuytsia 20: 229–259 (2010)
A new myrtaceous genus endemic to south-western Australia is described as Enekbatus Trudgen & Rye. It is related to Rinzia Schauer and several other genera, all of which have an unmodified anther type, a multilocular ovary and reniform seeds. However, the indehiscent fruit of the new genus separates it from all other members of this group. Ten species are recognised here, of which seven are newly described as Enekbatus bounites Trudgen & Rye, E. cristatus, E. dualis, E. eremaeus, E. longistylus, E. planifolius and E. sessilis. The new combinations Enekbatus cryptandroides (F. Muell.) Trudgen & Rye, E. clavifolius (S.Moore) Trudgen & Rye and E. stowardii (S.Moore) Trudgen & Rye, are made for three species that were previously included in Baeckea L. s. lat. This revision includes a key to the species, distribution maps and illustrations.
The status of infraspecific taxa and new subspecies in Ptilotus stirlingii (Amaranthaceae)
DAVIS, R.W. AND BUTCHER, R., Nuytsia 20: 261–270 (2010)
This paper evaluated current infraspecific taxa within Ptilotus stirlingii (Lindl.) F.Muell. using morphometric analysis. We conclude that var. pumilus Benl should no longer be recognised as a distinct variety from var. stirlingii and that var. laxus (Benth.) Benl and var. minutus Benl should be merged into a single taxon. The new name P. stirlingii subsp. australis R.W.Davis & R.Butcher is erected for this taxon and var. stirlingii is elevated in rank. With these changes, P. stirlingii now comprises two subspecies rather than four varieties. Revised descriptions and a key are presented for the new subspecies.
Logania sylvicola (Loganiaceae), a new species from south-west Western Australia
CRANFIELD, R.J., HISLOP, M. AND MACFARLANE, T.D., Nuytsia 20: 271–275 (2010)
Logania sylvicola Cranfield, Hislop & Macfarlane, a new species endemic to the Jarrah Forest Bioregion of south-west Western Australia, is described, illustrated and mapped.
Darwinia hortiorum (Myrtaceae: Chamelaucieae), a new species from the Darling Range, Western Australia
THIELE, K.R., Nuytsia 20: 277–281 (2010)
The distinctive, new, rare species Darwinia hortiorum is described, illustrated and discussed. Uniquely in the genus it has strongly curved-zygomorphic flowers with the sigmoid styles arranged so that they group towards the centre of the head-like inflorescences.
Myxomycota census of Western Australia
KNIGHT, K.J. AND BRIMS, M.H., Nuytsia 20: 283–307 (2010)
A census of the slime mould species found in Western Australia, based on publications recording slime mould species and collections housed at the Western Australian Herbarium (PERTH), is presented. A total of 159 species in 37 genera and 12 families are recorded.
Two new taxa of Verticordia (Myrtaceae: Chamelaucieae) from south-western Australia
GEORGE, A.S. AND BARRETT, M.D., Nuytsia 20: 309–318 (2010)
Verticordia mitchelliana subsp. implexior A.S.George & M.D.Barrett and Verticordia setacea A.S.George are described and discussed. V. setacea belongs with V. gracilis A.S.George in section Platandra, previously a monotypic section.
Tetratheca sp. Mt Solus (F. Obbens 307/98) (Elaeocarpaceae) is not distinct from Tetratheca affinis
BUTCHER, R., Nuytsia 20: 319–320 (2010)
Tetratheca sp. Mt Solus (F. Obbens 307/98) was collected once from Mt Solus, in the Darling Range, in November 1998 but has never been relocated. This taxon was distinguished from T. affinis Endl. by its possession of only one ovule per loculus, compared with four or five ovules per loculus, as well as its geographic disjunction. Close examination of all specimens of T. affinis at PERTH has found that ovule number per loculus varies from one to five, and that Tetratheca sp. Mt Solus (F. Obbens 307/ 98) does not have any unique morphological features supporting its distinction from T. affinis. By contrast,three specimens of T. affinis from near Cape Riche were found to have a suite of subtle differences from typical T. affinis and have been placed on the Western Australian Plant Census as T. affinis subsp. Cape Riche (T.D. Macfarlane TDM 1832) pending further fieldwork and taxonomic study.
A nomenclatural correction in Verreauxia (Goodeniaceae)
GEORGE, A.S., Nuytsia 20: 321–322 (2010)
In the Flora of Australia vol. 35, p. 300 (1992), Roger Carolin used the name Verreauxia villosa E.Pritzel for a rather rare species of this small Western Australian genus. He cited Verreauxia dyeri E.Pritzel ex Hemsley as a synonym. The name V. villosa is current on FloraBase . In 2005, when checking the holdings of this species at Kew for imaging early Australian collections for the Global Biodiversity Information Facility/ Australian Virtual Herbarium project, I found that the second of these names seems to be correct as its publication predates that of the former by just a few weeks. A typographical error in a date of publication apparently led to the previous interpretation.
A lectotype and new combination in Hypocalymma (Myrtaceae: Chamelaucieae)
RYE, B.L., Nuytsia 20: 323–326 (2010)
Hypocalymma (Endl.) Endl. was first described as a section of Leptospermum J.R.Forst. & G.Forst. and shortly afterwards raised to the generic level (Endlicher 1837, Endlicher 1840). It was based on the two species now known as H. angustifolium (Endl.) Schauer and H. robustum (Endl.) Lindl. In their recent review of the genus, Strid and Keighery (2002) recorded H. angustifolium as the type species, but they did not lectotypify it nor refer to any previous lectotypification. As H. robustum appears to be a better match for the protologue, that species is selected here as the lectotype.
Five new species of Calandrinia (Portulacaceae) from Western Australia with additional information on morphological observations
OBBENS, F.J., Nuytsia 21 (1): 1–23 (2011)
Four new Western Australian species in Calandrinia section Pseudodianthoideae von Poellnitz are described as: C. flava Obbens C. tholiformis Obbens, C. sculpta Obbens & J.G.West and C. vernicosa Obbens. A fifth species of uncertain sectional placement is described as C. pentavalvis Obbens. One of the new species is found solely in coastal areas of the South West Botanical Province, one occurs within the Eremaean Botanical Province while the remaining three occur in both these regions. Notes on some field and laboratory observations of the morphology of Calandrinia are discussed.
Wurmbea fluviatilis (Colchicaceae), a new riverine species from the Gascoyne region of Western Australia
MACFARLANE, T.D. AND CASE, A.L., Nuytsia 21 (1): 25–30 (2011)
A new species of Wurmbea, W. fluviatilis T.Macfarlane & A.Case, is described and illustrated with photographs and a distribution map. The new species is known from only three populations from the Gascoyne River catchment in the region of Mount Augustus, growing on river banks and beside riverside pools. It is a relatively tall, attractive species with bi-coloured flowers.
Valid publication of Ptilotus stirlingii subsp. australis (Amaranthaceae)
DAVIS, R.W. AND BUTCHER, R., Nuytsia 21 (1): 31–32 (2011)
In an oversight in a paper (Davis & Butcher 2010) resolving the status of infraspecific taxa in Ptilotus stirlingii (Lindl.) F.Muell. the Latin diagnosis for the new subspecies Ptilotus stirlingii subsp. australis R.W.Davis & R.Butcher was omitted, thereby rendering the name invalidly published under the International Code of Botanical Nomenclature. This omission is rectified here, and the new subspecies formally described.
Removal of the informal name Epiblema grandiflorum var. cyaneum ms from the Census of Western Australian Plants
THIELE, K.R., Nuytsia 21 (1): 33–34 (2011)
While conservation of unusual variants of any plant species is desirable, taxonomic recognition of such variants is not warranted unless evidence is available that they represent genetically distinct evolutionary lineages. Geographically restricted variants such as E. grandiflorum var. cyaneum ms are no more likely to warrant taxonomic recognition than widespread and common variants. Removal of Epiblema grandiflorum var. cyaneum ms from the Census of Western Australian Plants is recommended.
New south-western Australian members of the genus Petrophile (Proteaceae: Petrophileae), including a hybrid
RYE, B.L., HISLOP, M., SHEPHERD, K.A. AND HOLLISTER, C., Nuytsia 21 (2): 35–67 (2011)
Four additional species are recognised in the genus Petrophile R.Br. ex J.Knight by the reinstatement of P. axillaris Meisn. and the description of three new species, P. globifera Hislop & K.A.Sheph., P. foremanii Hislop & Rye and P. septemfida Rye & K.A. Sheph. A hybrid between P. ericifolia R.Br. and P. seminuda Lindl. is documented, the new subspecies divaricata Hislop & K.A.Sheph. is named for P. conifera Meisn., and a lectotype is selected for P. seminuda var. indivisa Benth. There is also a key for members of the genus occurring in Western Australia, excluding those belonging to Petrophile sect. Arthrostigma (Endl.) Kuntze.
Stackhousia stratfordii (Celastraceae: Stackhousioideae), a remarkable new species from a remote location near Norseman, south-west Western Australia
BARKER, W.R. AND COCKERTON, G.T.B., Nuytsia 21 (2): 69–74 (2011)
Stackhousia stratfordii W.R.Barker & Cockerton sp. nov. possesses attributes unique to its genus and subfamily of opposite sub-radical leaves and flowers borne in scapes and containing three stamens. Morphological evidence is summarised arguing its placement within Stackhousia . The Stackhousioideae Burnett are a subfamily distinctive in Celastraceae R.Br. for their herbaceous life-form, mainly moth-pollinated, tubular flowers, and fruits that are single-seeded indehiscent mericarps (cocci) (Barker 1983, 1984, in press); in terms of diversity they are centred in Australia, occurring in much of the continent, in temperate arid, semi-arid and sub-tropical regions. Until recently a separate family (Stackhousiaceae R.Br.), the subfamily has morphological and geographic features unique in the family Celastraceae, in which they have been placed in the last decade (Kubitzki 2004a, b; Simmons 2004 a, b). It comprises three genera: Tripterococcus Endl. with three species , confined to south-west Western Australia, Macgregoria F.Muell., a single species spread across the southern half of arid Australia, and Stackhousia Sm. with over 30 species spread over the geographical and climatic range of the subfamily in Australia, with a single species in New Zealand and another spread into Malesia, the Philippines and Micronesia (Barker, in press).
New, locally endemic taxa in Leucopogon (Ericaceae: Styphelioideae: Styphelieae) from the Perth and midwest regions of Western Australia
HISLOP, M., Nuytsia 21 (2): 75–89 (2011)
Four new taxa, Leucopogon maritimus Hislop, L. nitidus Hislop, L. stokesii Hislop, and L. squarrosus Benth. subsp. trigynus Hislop are described and mapped; the first three are illustrated. All have very restricted distributions and are of high conservation priority. Lectotypes for L. squarrosus and L. brachycephalus DC. var. heterophyllus Sond. are designated.
Labichea rossii (Fabaceae: Caesalpinioideae), a new species from the Yilgarn Ranges, Western Australia
GIBSON, N., Nuytsia 21 (3): 91–95 (2011)
A new rare species of Labichea Gaudich. ex DC. is described from a ridge of Banded Iron Formation in the ranges near Mt Holland. Unlike most species in the genus, this new species, L. rossii N.Gibson, has very dissimilar petals more reminiscent of flowers from subfamily Faboideae.
A new and rare species of Ptilotus (Amaranthaceae) from a suburban wetland of the eastern Swan Coastal Plain, Western Australia
DAVIS, R.W. AND TAUSS, C., Nuytsia 21 (3): 97–102 (2011)
Ptilotus christineae R.W.Davis & Tauss, currently known from only one small population in the Greater Brixton Street Wetlands, about 14 km from the centre of the city of Perth, is described and illustrated. A key to Ptilotus R.Br. of the Swan Coastal Plain Biogeographical Region is provided.
An assessment of some infraspecific taxa in Ptilotus (Amaranthaceae) from Western Australia
DAVIS, R.W., Nuytsia 21 (3): 103–106 (2011)
This paper deals with three infraspecific taxa in Ptilotus that do not warrant recognition: Ptilotus appendiculatus Benl var. minor Benl, Ptilotus divaricatus (Gaudich.) F.Muell. var. rubescens Benl and Ptilotus lanatus Cunn. ex Moq. var. glabrobracteatus Benl.
A revision of Dielsiodoxa (Ericaceae: Styphelioideae: Oligarrheneae)
ALBRECHT, D.E. AND HISLOP, M., Nuytsia 21 (3): 107–126 (2011)
The genus Dielsiodoxa Albr., endemic to south-west Western Australia, is revised. The genus includes three previously named species, D. leucantha (E.Pritz.) Albr., D. oligarrhenoides (F.Muell.) Albr. and D. tamariscina (F.Muell.) Albr. A neotype is designated for the former species and a lectotype for the latter species. Three new taxa are described with accompanying scanned images: D. lycopodioides Albr., D. propullulans Albr. and D. leucantha subsp. obtusa Hislop & Albr. Descriptions, a distribution map and a key to all taxa are provided.
Sida picklesiana (Malvaceae), a new species from the Murchison-Gascoyne region of Western Australia
MARKEY, A.S., DILLON, S.J., COCKERTON, G.T.B. AND BARKER, R.M., Nuytsia 21 (3): 127–137 (2011)
This article provides a description of the recently discovered species Sida picklesiana A.S. Markey, S.J. Dillon & R.M. Barker. This species is known from an area near Wiluna in Western Australia’s Murchison-Gascoyne region, where it occurs in a variety of habitats. Sida picklesiana has conservation priority status as it has a relatively limited distribution. Major differences between Sida picklesiana and the species with which it is most likely to be confused are discussed, and the most recently published draft key to Sida is amended to include this new species.
Two species of Inocybe (fungi) introduced into Western Australia
BOUGHER, N.L. AND MATHENY, P.B., Nuytsia 21 (3): 139–148 (2011)
This paper reports for the first time the introduction into Western Australia from the northern hemisphere of Inocybe curvipes P.Karst. and Inocybe rufuloides Bon. The fungi are associated with planted non-native ectomycorrhizal trees – Quercus, Pinus, and possibly Salix. Previously, I. curvipes was confirmed from South Australia where it has been present for at least almost a century, but it was not known from Western Australia. I. rufuloides had not been recorded anywhere in Australia. In this paper I. curvipes is also reported for the first time in Papua New Guinea, in association with planted Quercus and Pinus. Populus and Quercus are confirmed as ectomycorrhizal partners of I. curvipes based on ITS BLASTn analysis of environmental sequences.
Eremophila koobabbiensis (Scrophulariaceae), a new, rare species from the wheatbelt of Western Australia
CHINNOCK, R.J. AND DOLEY, A.B., Nuytsia 21 (4): 157–162 (2011)
Eremophila koobabbiensis Chinnock, sp.nov., is described and illustrated. This rare species is known only from one area north of Moora and its conservation is discussed. It is also established in cultivation and its long-term survival is assured.
A reinstatement and a new combination in Leucopogon (Ericaceae: Styphelioideae: Styphelieae)
HISLOP, M., Nuytsia 21 (4): 163–176 (2011)
The group of species synonymised by Bentham (1868) under Leucopogon revolutus R.Br. are re-examined and found to be heterogeneous. As a result L. rubricaulis R.Br. is reinstated. Two morphotypes identified within L. obovatus (Labill.) R.Br. (erroneously treated by Bentham as L. revolutus) are described as subspecies and the combination L. obovatus (Labill.) R.Br. subsp. revolutus (R.Br.) Hislop is here published. Descriptions and illustrations are provided for the three taxa treated and their distributions are mapped.Lectotypes are designated for L. capitellatus DC. var. sparsiflorus Sond., L. revolutus, L. rubricaulis and L. villosus R.Br.
Amanita ochroterrea and Amanita brunneiphylla (Basidiomycota), one species or two?
DAVISON, E.M., Nuytsia 21 (4): 177–184 (2011)
Amanita ochroterrea (Gentilli) Bas and A. brunneiphylla O.K.Miller are robust, macroscopically similar mushrooms described from the southwest of Western Australia. According to the protologue of A. brunneiphylla, the main difference between them is the presence (in A. ochroterrea) or absence (in A. brunneiphylla) of clamp connections. However in the current study abundant clamp connections have been observed in the holotype and paratypes of A. brunneiphylla. As other microscopic characters are indistinguishable, A. brunneiphylla is synonymised with A. ochroterrea, and an expanded description presented.
Two new species from the Leucopogon distans group (Ericaceae: Styphelioideae: Styphelieae) and the reinstatement of L. penicillatus
HISLOP, M., Nuytsia 22 (1): 1–16 (2012)
Two new species, Leucopogon microcarpus Hislop and L. newbeyi Hislop are described and another, L. penicillatus Stschegl., previously reduced by Bentham (1868) to a variety of L. distans R.Br., is reinstated. All three are illustrated and their distributions mapped. A key is provided for all Western Australian taxa currently referred to the L. distans group (sensu Hislop & Chapman 2007). Lectotypes are designated for L. distans and L. reflexus R.Br. Taxonomic and nomenclatural notes pertaining to L. atherolepis Stschegl.and L. reflexus are also included.
Two new mallee box species (Eucalyptus sect. Adnataria ser. Lucasianae; Myrtaceae) from the Pilbara region of Western Australia
NICOLLE, D. AND FRENCH, M.E., Nuytsia 22 (1): 17–29 (2012)
Two new species are described, both which have previously been included in E. lucasii Blakely, viz: E. aridimontana D.Nicolle & M.E.French sp. nov., known from high mountain ridges of the Hamersley Range, and E. rowleyi D.Nicolle & M.E.French sp. nov., known from plains of the De Grey River catchment to the north-east of the Hamersley Range. Both species differ from E. lucasii in their adult leaves which age to green and/or glossy, and in their thickened pedicels and peduncles (among other characteristics). Eucalyptus lucasii, as now circumscribed, is a widespread species restricted to watercourses and flood-out plains south of the Pilbara region. A key to E. ser. Lucasianae Chippend. and distribution maps for E. lucasii, E. aridimontana and E. rowleyi are provided.
A new species of Gompholobium (Fabaceae: Mirbelieae) from the Pilbara bioregion of Western Australia
WILKINS, C.F. AND TRUDGEN, MALCOLM E., Nuytsia 22 (1): 31–40 (2012)
Gompholobium oreophilum C.F.Wilkins & Trudgen, a new species from the Pilbara bioregion of Western Australia, is described and compared to its close relatives G. karijini Chappill and G. polyzygum F.Muell. The different habitat preferences and the possible hybridisation between G. oreophilum and G. karijini, which is also endemic to the Pilbara, are discussed. A key and distribution maps are provided.
Leucopogon navicularis (Ericaceae: Styphelioideae: Styphelieae), another local endemic from the midwest region of Western Australia
HISLOP, M., Nuytsia 22 (2): 45–50 (2012)
Leucopogon navicularis Hislop, a new and potentially rare species, is described, illustrated and its distribution mapped.
Acacia bartlei (Fabaceae: Mimosoideae), a new species from near Esperance, Western Australia
MASLIN, B.R. AND REID, J.E., Nuytsia 22 (2): 51–56 (2012)
Acacia bartlei Maslin & J.E.Reid, a new, rare species of Acacia Mill. related to A. redolens Maslin, is described. It is restricted to a small area north and north east of Esperance, Western Australia, where it grows in often waterlogged depressions.
Five new species and records of Inocybe (Agaricales) from temperate and tropical Australia
BOUGHER, N.L. AND MATHENY, P.B., Nuytsia 22 (2): 57–74 (2012)
Five species of Inocybe are documented from Australia, four from southern temperate regions and one from the northern tropics. Inocybe emergens, previously known only from the type collection in South Australia, is reported for the first time from south-west Western Australia. Inocybe fulvilubrica Matheny, Bougher & G.Gates and I. redolens Matheny, Bougher & G.Gates are both described from Western Australia and Tasmania. Inocybe fulvilubrica has nodulose spores, a yellowish brown pileus that may be viscid or greasy and bears patches of white velar material, and a white pruinose stipe with a marginate bulb. Inocybe redolens is distinguished by the combination of nodulose spores, a squamulose disc, lack of caulocystidia, and an odour of Pelargonium. Inocybe sinuospora Matheny & Bougher known only from southwest Western Australia, has distinctive oblong- angular spores with a sinuous outline. Inocybe torresiae Matheny, Bougher & M.D.Barrett is a tropical species with nodulose spores described from forests in northern Western Australia and Queensland. It is distinguished by its truncate or sessile hymenial cystidia, presence of caulocystidia, and sweet or citrine odour.
Three new species allied to the ‘Mirbelia viminalis group’ (Fabaceae: Mirbelieae), from Western Australia
BUTCHER, R., Nuytsia 22 (2): 75–92 (2012)
Mirbelia balsiformis R.Butcher, M. corallina R.Butcher and M. ferricola R.Butcher are described herein as new species allied to the ‘M. viminalis group’ Of the newly described species, M. balsiformis is widely distributed between Kalbarri and Shark Bay, and is not conservation-listed, while M. corallina and M. ferricola are listed as Priority Three conservation taxa in Western Australia. Mirbelia corallina is restricted to sandplains in the Kalbarri area, with most collections from Kalbarri National Park. Mirbelia ferricola is restricted to Banded Iron Formation ranges between the Koolanooka Hills, east of Morawa, and the Bremer Range, west of Norseman. Although this species has a wide area of occupancy, the biodiverse ranges on which it occurs are small, disjunct islands in an otherwise subdued landscape, and are highly prospective for mining. The putative taxon M. sp. Carnarvon (J.S. Beard 6008), previously poorly defined, appears to be a recognisable variant within the variable M. ramulosa (Benth.) C.A.Gardner. The name is retained on Western Australia’s plant census, however, until its status can be clarified by a comprehensive study of variation in M. ramulosa across its range. This paper describes, illustrates and provides distribution maps for M. balsiformis, M. corallina and M. ferricola, and distinguishes them from similar, scale-leaved Mirbelia Sm. species in Western Australia. A key to species of the ‘M. viminalis group’ is also provided.
Notes on the identity and status of Western Australian phrase names in Corymbia and Eucalyptus (Myrtaceae)
NICOLLE, D., FRENCH, M.E. AND THIELE, K.R., Nuytsia 22 (3): 93–110 (2012)
A total of 27 phrase names in Corymbia K.D.Hill & L.A.S. Johnson (1) and Eucalyptus L'Hér. (25) which occur at least partly in Western Australia have been assessed with respect to their identity and status. Of these 27 phrase names, we recommend that 14 be removed from duplicate names (taxonomically matching another phrase name or published taxon), are taxonomically indistinct or very poorly understood, or are considered to represent hybrids. We erect eight new phrase names for Eucalyptus in Western Australia.
Tetratheca spenceri (Elaeocarpaceae), a new rare and range-restricted species from the Coolgardie bioregion, Western Australia
BUTCHER, R. AND COCKERTON, G.T.B., Nuytsia 22 (3): 111–120 (2012)
The new species of Tetratheca Sm. described herein was discovered opportunistically by Goldfields resident Charlie Spencer while exploring the Coolgardie bioregion in late 2011; it is named T. spenceri R.Butcher & Cockerton in honour of him. Tetratheca spenceri is currently known from a single population on a laterite outcrop south-east of Coolgardie and is of conservation significance. Five rare, short-range endemic Tetratheca taxa are already known from Banded Iron Formation ranges in the Coolgardie bioregion. Tetratheca spenceri can be distinguished from all other species of Tetratheca in the region by its combination of straight, finely wrinkled, glaucous stems, alternate, appressed, narrowly deltoid scale-leaves, moderately long peduncles bearing long, glandular hairs, uniformly pink petals, two ovules per locule, which are crowded together near the apex of the septum, and narrowly obovate, glabrous fruit. The new species is described and illustrated herein, its affinities are discussed, and its distribution mapped. A key to the ‘leafless’ taxa of Tetratheca in Western Australia is included.
A taxonomic revision of Mulga (Acacia aneura and its close relatives: Fabaceae) in Western Australia
MASLIN, B.R. AND REID, J.E., Nuytsia 22 (4): 129–267 (2012)
A taxonomic revision of the highly diverse Western Australian Mulga flora (Acacia aneura F.Muell. ex Benth. and its close relatives) is presented, based on morphological analyses of almost 2000 herbarium collections complemented by field studies of about 300 populations (mostly located in Western Australia, with a few from the Northern Territory and South Australia). Twelve species accommodated in three informal groups, the Blue, Grey-green and Green Alliances, are recognised. Almost all of the species contain informal variants, and putative hybrids and/or intergrades are common. Because many of the species had previously been recognised as varieties of A. aneura (Pedley 2001) a discussion of our taxon concepts is given. The 12 species are defined by a combination of morphological characters, the most important being branchlet resin (translucent vs opaque) and pod margins (rimmed, bevel-edged or winged), complemented by new shoot (resinous vs non-resinous), phyllode (shape, size, curvature, nervature) and pod (width) attributes. A discussion of the taxonomically most informative characters in the Mulga group is presented. Seven new species are recognised: Acacia aptaneura Maslin & J.E.Reid (syn. A. aneura var. pilbarana Pedley and A. aneura var. tenuis Pedley), A. caesaneura Maslin & J.E.Reid (syn. A. aneura var. argentea Pedley), A. fuscaneura Maslin & J.E.Reid (syn. A. aneura var. fuliginea Pedley), A. incurvaneura Maslin & J.E.Reid (syn. A. aneura var. microcarpa Pedley), A. macraneura Maslin & J.E.Reid (syn. A. aneura var. macrocarpa Randell), A. mulganeura Maslin & J.E.Reid and A. pteraneura Maslin & J.E.Reid. Acacia aneura var. intermedia Pedley is provisionally regarded as conspecific with the broadly circumscribed A. aneura.
The type of Acacia aneura (Mulga) and ambiguities concerning the application of this name
MASLIN, B.R., O‘LEARY, M., REID, J.E. AND MILLER, J.T., Nuytsia 22 (4): 269–294 (2012)
Acacia aneura F.Muell. ex Benth. is a member of a large, taxonomically complex group of plants that are very common in the Australian arid zone. In order to help determine the application of this name the type collection of A. aneura at the National Herbarium of Victoria (MEL) is reassessed after visits to the type locality. This collection comprises rather fragmentary specimens mounted on three sheets (MEL 724215, 724218 and 724219), each labelled as having been collected [in 1851] by Ferdinand von Mueller from ‘Cudnaka’. This locality is now known as Kanyaka, located in the South Flinders Ranges, South Australia, between Quorn and Hawker. The holotype is confirmed as the depauperate fruiting specimen on MEL 724218. The fertile specimen on MEL 724219 is confirmed as belonging to a Mulga taxon of uncertain status and is not a type. The sterile specimen on MEL 724215 and the sterile specimens on MEL 724219 may or may not be types, but their status cannot be determined with any certainty. The populations at Kanyaka that Mueller presumably visited were sampled by the authors in 2007, 2008 and 2010. Subsequent study showed there to be two distinct Mulga morphotypes in these populations. One morphotype corresponds to the type of A. aneura but the status of the second morphotype is uncertain. The latter does not match the fertile specimen on MEL 724219 and appears not to have been collected by Mueller; it may possibly represent a hitherto undescribed species. The taxonomic status of the first morphotype, and hence the application of the name A. aneura, is currently uncertain. Further field, morphological and genetic studies, especially of South Australian populations, are needed to resolve the application of the name A. aneura and also to establish the status of the second morphotype collected from the type locality.
Description of six Lepidosperma species (Cyperaceae) based on type specimens
BARRETT, R.L., Nuytsia 22 (5): 295–322 (2012)
Many species of Lepidosperma Labill. have been poorly circumscribed, resulting in significant nomenclatural confusion. Full descriptions of six species based solely on type specimens held in the Webb Herbarium in Florence (FI-W) and the Preiss Herbarium in Lund (LD) are presented here in order to facilitate accurate application of the names involved. Descriptions are provided for Lepidosperma costale Nees, L. gladiatum Labill., L. fimbriatum Nees, L. humile (Nees) Boeck., L. longitudinale Labill. and L. squamatum Labill., as well as notes about these species.
A new species of Monotoca (Ericaceae: Styphelioideae: Styphelieae) from the south coast of Western Australia
CHAPMAN, A.R., Nuytsia 22 (5): 323–328 (2012)
A new species, Monotoca aristata A.R. Chapman from the west of Fitzgerald River National Park is described and illustrated. It is distinguished from all other Monotoca species by the thick, aristate, linear-lanceolate leaves, with conspicuous veins on the abaxial surface. It is now the only representative of this genus in Western Australia.
Solanum albostellatum (Solanaceae), a new species from the Pilbara bioregion of Western Australia
DAVIS, R.W. AND HURTER, P.J.H., Nuytsia 22 (5): 329–334 (2012)
Solanum albostellatum R.W.Davis & P.J.H.Hurter has recently been discovered and is formally described. The new species is morphologically similar to S. oldfieldii F.Muell. and S. esuriale Lindl. Solanum albostellatum inhabits cracking clay environments extending from Millstream Chichester National Park to the Hamersley Range, west of Newman. An amendment to the Flora of Australia key for Solanum to account for S. albostellatum is included, as is a table summarising the similarities and differences between S. albostellatum and the most similar taxa.
Ptilotus christineae is synonymous with the previously Presumed Extinct taxon P. pyramidatus
DAVIS, R.W., Nuytsia 22 (5): 335 (2012)
While curating the Ptilotus R.Br. collection at the Western Australian Herbarium, I came across a small line drawing of the Presumed Extinct species P. pyramidatus (Moq.) F.Muell. This name is based on a Drummond collection of unknown provenance. It was immediately clear from the habit depicted that it could represent an earlier name for the recently published P. christineae R.W.Davis & Tauss. Subsequent examination of type material confirmed that P. pyramidatus is conspecific with P. christineae and the latter name must therefore be reduced to synonymy. The specimens collected in Perth in late 2010, which formed the basis for the description of P. christineae, represent the first collections of P. pyramidatus for more than 160 years.
A newly discovered population at Cape Le Grand supports Lucky Bay as the type locality of Banksia plumosa (Proteaceae)
MARKEY, A.S., Nuytsia 22 (5): 337–340 (2012)
The type gathering of Banksia plumosa (R.Br.) A.R.Mast & K.R.Thiele was collected by Robert Brown from Bay 1 (Lucky Bay, c. 35 km east of Esperance) in January 1802 (Figure 1). Over the following two centuries, further collections of this species have been made in an area from the Stirling Range and Albany eastwards to the Fitzgerald River (Western Australian Herbarium 1998–). However, B. plumosa has not been recorded again from any area east of Bremer Bay. George (1999) concluded that the type locality was in error, and that the more likely type location was in the Albany district (King George Sound), where Brown collected from late December 1801 to early January 1802 (Vallance et al. 1993).
Tephrosia oxalidea (Fabaceae: Millettieae), a new species from the Pilbara and Gascoyne bioregions of Western Australia
BUTCHER, R. AND HURTER, P.J.H., Nuytsia 22 (6): 341–349 (2012)
The Australian species of Tephrosia Pers. (Fabaceae: Millettieae) have not been revised in full since Bentham’s Flora Australiensis, although considerable work towards this goal has been performed at the herbaria of the Northern Territory (DNA) and Queensland (BRI) to date. Taxonomic work is now underway on the Tephrosia of Western Australia, with Western Australia’s plant census currently recording 23 informally named taxa in this State. One of these, Tephrosia sp. Cathedral Gorge (F.H. Mollemans 2420), is a distinctive species and is described herein as T. oxalidea R.Butcher & P.J.H.Hurter. Images and a distribution map for this species are included, as is a discussion of its affinities.
Three new species of Calandrinia (Portulacaceae) from the Eremaean and South West Botanical Provinces of Western Australia
OBBENS, F.J., Nuytsia 22 (6): 351–362 (2012)
Three new species in Calandrinia Kunth. sect. Pseudodianthoideae Poelln. are described: C. hortiorum Obbens, C. umbelliformis Obbens and C. operta Obbens. The first two species are located within the Eremaean Botanical Province while the last species has a disjunct distribution in both the Eremaean and South West Botanical Provinces.
Atalaya brevialata (Sapindaceae), a new species from the Northern Territory, Australia
COWIE, I.D. AND STUCKEY, B., Nuytsia 22 (6): 363–370 (2012)
A new, rare species, Atalaya brevialata Cowie & G.M. Wightman is described and illustrated. The species is unusual in the genus in having a greatly reduced wing on the samara and the suffruticose growth habit, the latter perhaps an adaption to the region’s wet-dry tropical climate and prevailing near-annual fire regime. It appears to have a restricted distribution to the south of Darwin and its conservation status is evaluated. A key to species of Atalaya Blume in the Northern Territory and Western Australia is provided.
A revision of the Australian endemic genus Pentalepis (Asteraceae: Ecliptinae)
ORCHARD, A.E. AND CROSS, E.W., Nuytsia 22 (6): 371–392 (2012)
The genus Pentalepi F.Muell., resurrected by Karis et al. in 1993, with two species, after being for many years included in Moonia Arn or Chrysogonum L., has been studied morphologically across its full range. Four new species (P. linearifolia Orchard, P. grandis E.W.Cross, P. kakaduensis E.W.Cross and P. walcottii E.W.Cross) are described, as well as three subspecies in P. trichodesmoides F.Muell. (subsp. trichodesmoides, subsp. hispida Orchard and subsp. incana Orchard), two in P. linearifolia (subsp. linearifolia and subsp. nudibranchoides Orchard) and two in P. ecliptoides F.Muell. (subsp. ecliptoides and subsp. hirsuta Orchard), bringing the total to six species and eight subspecies. All taxa are keyed, described, illustrated and mapped.
Seven new combinations for Western Australian members of Myrtaceae tribe Chamelaucieae
RYE, B.L. AND TRUDGEN, MALCOLM E., Nuytsia 22 (6): 393–398 (2012)
The following new combinations are made for Myrtaceous species in the tribe Chamelaucieae: Anticoryne ovalifolia (F.Muell.) Rye, Cyathostemon ambiguus (F.Muell.) Rye & Trudgen, C. blackettii (F.Muell.) Rye & Trudgen, C. heterantherus (C.A.Gardner) Rye & Trudgen, Malleostemon decipiens (W.Fitzg.) Trudgen, Tetrapora floribunda (Benth.) Trudgen & Rye and T. tenuiramea (S. Moore) Trudgen & Rye. The type gatherings for the base name Baeckea floribunda Benth. are discussed.
Poranthera moorokatta (Phyllanthaceae), a rare new species from Perth, Western Australia
BARRETT, R.L., Nuytsia 22 (6): 399–407 (2012)
Poranthera moorokatta R.L.Barrett is described as a new species recently discovered in Banksia woodland in Kings Park, in the heart of the Perth metropolitan area. Poranthera moorokatta is morphologically allied to P. triandra J.M.Black, a woodland species distributed from Lake King in Western Australia to the Grampians in Victoria, and perhaps also to P. dissecta Halford & R.J.F.Hend., a species from granite outcrops in south-east Western Australia.
A revision of Eucalyptus ser. Falcatae (Myrtaceae) from south-western Australia, including the description of new taxa and comments on the probable hybrid origin of E. balanites, E. balanopelex and E. phylacis
NICOLLE, D. AND FRENCH, M.E., Nuytsia 22 (6): 409–454 (2012)
Twenty terminal taxa (including 18 species) are recognised in Eucalyptus ser. Falcatae. Brooker & Hopper. We include the monotypic E. ser. Cooperianae L.A.S.Johnson ex Brooker (E. cooperiana F.Muell.) in the series. The new species E. annettae D.Nicolle & M.E.French and E. opimiflora D. Nicolle & M.E.French and the new subspecies E. goniantha Turcz. subsp. kynoura D.Nicolle & M.E.French are described. New combinations made are E. adesmophloia (Brooker & Hopper) D.Nicolle & M.E.French, E. ecostata (Maiden) D.Nicolle & M.E.French and E. notactites (L.A.S.Johnson & K.D.Hill) D. Nicolle & M.E.French. The circumscription of some taxa is significantly modified from previous accounts, including that of E. falcata Turc E. goniantha and E. obesa Brooker & Hopper. The name E. dorrienii Domin is resurrected to accommodate populations of mallees previously erroneously called E. falcata. We reject the status of the following previously accepted taxa: E. argyphea L.A. S.Johnson & K.D.Hill (= E. falcata), E. balanites Grayling & Brooker (= E. decipiens × E. lane-poolei), E. balanopelex L.A.S.Johnson & K.D.Hill (= E. semiglobosa × E. kessellii subsp. eugnosta), E. communalis Brooker & Hopper (= E. adesmophloia – E. obesa intergrade), E. decipiens subsp. chalara Brooker & Hopper (= E. decipiens – E. adesmophloia intergrade) and E. phylacis L.A.S.Johnson& K.D.Hill (= E. decipiens × E. virginea). Distribution maps and representative images are provided where appropriate. A key to the taxa of E. ser. Falcatae is provided.
A review of Eucalyptus erythronema (Myrtaceae) from the wheatbelt of south-western Australia
NICOLLE, D. AND FRENCH, M.E., Nuytsia 22 (6): 455–463 (2012)
Three taxa are recognised within the previously-accepted concept of E. erythronema Turcz_._ The taxon previously known as E. erythronema var. marginata (Benth.) Domin is regarded as specifically distinct and is here described as E. armillata D.Nicolle & M.E.French. The taxon previously known as E. erythronema var. erythronema has two variants: a north-eastern variant with conspicuously waxy branchlets and usually red flowers, which we recognise as E. erythronema subsp. erythronema, and a south-western variant with non-waxy branchlets and consistently pale creamy yellow flowers, which we describe as E. erythronema subsp. inornata D.Nicolle & M.E.French_._ A distribution map for the three taxa previously included in E. erythronema and a key to E. ser. Elongatae Blakely (in which the three taxa treated here are included) are provided.
New combinations in Senegalia (Fabaceaee: Mimosoideae) for Australia
MASLIN, B.R., Nuytsia 22 (6): 465–468 (2012)
The genus Acacia Mill. (sens. lat.) is now regarded as comprising five genera, one of which is Senegalia Raf. This genus is represented in Australia by just four species, two native and two introduced. The following new combinations are made in order to facilitate the completion of a revised edition of the Flora of Australia vol. 11: Senegalia chundra (Roxb. ex Rottler) Maslin, Senegalia pennata (L.) Maslin and Senegalia pennata subsp. kerrii (I.C. Nielsen) Maslin.
Swainsona thompsoniana (Fabaceae: Faboideae: Galegeae), a new species endemic to the Pilbara bioregion of Western Australia
DAVIS, R.W. AND HURTER, P.J.H., Nuytsia 23: 1–4 (2013)
Swainsona thompsoniana R.W.Davis & P.J.H.Hurter is described here as new. An amendment to an existing key for Swainsona Salisb. is provided to account for S. thompsoniana. Swainsona thompsoniana occurs on cracking clay soils from east of Pannawonica to Mount Florence Station and south-east to Tom Price and Wittenoom; a distribution map is included.
Solanum zoeae (Solanaceae), a new species of bush tomato from the North Kimberley, Western Australia
BARRETT, R.L., Nuytsia 23: 5–21 (2013)
Recent surveys in the North Kimberley have brought numerous new species to light. Studies have revealed considerable taxonomic complexity in the genus Solanum L. in the Kimberley region that requires the recognition of a number of new taxa. Solanum zoeae R.L. Barrett is described here following collection of the first fertile material on a remote sandstone outcrop on Doongan Station. Notes are provided on all phrase-named Solanum taxa currently recognised in the Kimberley region and a revised key to Solanum species in the Kimberley region is provided.
Four new species of Astroloma (Ericaceae: Styphelioideae: Styphelieae) from Western Australia
HISLOP, M., WILSON, A.J.G. AND PUENTE-LELIÈVRE, C., Nuytsia 23: 23–42 (2013)
Four new species of Astroloma R.Br. s. str. (A. acervatum Hislop & A.J.G.Wilson, A. chloranthum Hislop & A.J.G.Wilson, A. inopinatum Hislop and A. oblongifolium A.J.G.Wilson & Hislop) are described, illustrated and mapped. The current taxonomic status of Astroloma is discussed in the light of significant changes that are pending in the Styphelia clade to which the genus belongs. A key to members of Astroloma s. str. with pale yellow, cream and/or green flowers is provided.
A revision of the Australian species of Eclipta (Asteraceae: Ecliptinae) with discussion of extra-Australian taxa
ORCHARD, A.E. AND CROSS, E.W., Nuytsia 23: 43–62 (2013)
The genus Eclipta L., of six species, is native to South America and Australia, with one species, E. prostrata (L.) L., a pantropical and warm temperate weed. The number of taxa currently recognised in the genus is discussed. The Australian taxa, comprising three species and two subspecies (E. prostrata, E. alatocarpa Melville and E. platyglossa F.Muell. subsp. platyglossa and subsp. borealis E.W.Cross & Orchard, subsp. nov.) have been studied morphologically across their full range. A lectotype is chosen for E. platyglossa. All Australian taxa are keyed, described, illustrated and mapped, and extra-Australian taxa are keyed and described, and most illustrated.
Allan Cunningham’s Timor collections
ORCHARD, A.E. AND ORCHARD, T.A., Nuytsia 23: 63–88 (2013)
The visits of Allan Cunningham to Timor in 1818 and 1819, at the conclusion of Lieutenant Philip Parker King’s first and second survey voyages to the north coast of Australia, are summarised, and surviving collections held in the Natural History Museum herbarium and the herbarium, Royal Botanic Gardens, Kew are listed. The significance of the various labels found on these sheets is discussed.
Cochlospermum macnamarae (Bixaceae), a rare, new endemic from the Pilbara bioregion of Western Australia
HISLOP, M., THIELE, K.R. AND BRASSINGTON, D., Nuytsia 23: 89–94 (2013)
A new species of Cochlospermum Kunth, C.macnamarae Hislop, K.R.Thiele & Brassington, is described, illustrated and mapped. It occurs in the semi-arid Pilbara bioregion of Western Australia, unlike the other Australian species which all occur in the wet-dry tropics. A revised key to the genus in Australia is provided to accommodate the new species.
Two Western Australian species of Ozothamnus transferred to Pithocarpa (Asteraceae: Gnaphalieae)
BARRETT, R.L., SCHMIDT-LEBUHN, A.N. AND THIELE, K.R., Nuytsia 23: 103–108 (2013)
Two Western Australian species currently referred to the genus Ozothamnus R.Br. have in the past been considered poorly aligned with that genus, but their alternative placement has been uncertain. Recent molecular studies have suggested that they are best placed in the Western Australian endemic genus Pithocarpa Lindl. The following new combinations are made: Pithocarpa cordata (DC.) Schmidt-Leb. & R.L.Barrett and Pithocarpa ramosa (DC.) Schmidt-Leb. & R.L.Barrett. Four species are now recognised in Pithocarpa and all are listed here. A key to the expanded genus is provided. Scanning electron micrographs are provided for a range of features for all taxa.
Pleurocarpaea gracilis (Asteraceae: Vernonieae), a new species from the Pilbara region of Western Australia
LANDER, N.S. AND HURTER, P.J.H., Nuytsia 23: 109–115 (2013)
A new species of Asteraceae, Pleurocarpaea gracilis Lander & P.J.H.Hurter, is described from the Pilbara region of Western Australia. A key to all three species now included in Pleurocarpaea Benth. is provided.
Pilbara, a new genus of Asteraceae (tribe Astereae) from Western Australia
LANDER, N.S., Nuytsia 23: 117–123 (2013)
A new monotypic composite genus endemic to the Hamersley Range of Western Australia is described and the new species Pilbara trudgenii Lander is illustrated and mapped. Its affinities within the tribe Astereae Cass. are discussed. The new species is an obligate lithophyte.
A taxonomic review of the Solanum sturtianum subgroup of subgenus Leptostemonum (Solanaceae)
BEAN, A.R., Nuytsia 23: 129–161 (2013)
The informal taxonomic subgroup typified by Solanum sturtianum F.Muell. comprises those species that have stellate hairs, black mature fruits with a thin brittle pericarp, and brown to black seeds. The subgroup is endemic to Australia. Ten species are recognised here: S. sturtianum is maintained, S. morrisonii Domin is reinstated, and eight new species are described viz. S. austropiceum A.R.Bean, S. elatius A.R.Bean, S. iodinum A.R.Bean, S. kentrocaule A.R.Bean, S. octonum A.R.Bean, S. piceum A.R.Bean, S. pycnotrichum A.R.Bean and S. reclusum A.R.Bean. A lectotype is chosen for S. morrisonii. Descriptions, illustrations and distribution maps are provided for all species.
A re-assessment of the varieties recognised in Verticordia plumosa (Myrtaceae: Chamelaucieae)
HARRIS, A.M. AND RYE, B.L., Nuytsia 23: 163–170 (2013)
The seven varieties of Verticordia plumosa (Desf.) Druce are re-assessed in the light of recent collections. Verticordia plumosa var. pleiobotrya A.S.George is reduced to a synonym of V. plumosa var. brachyphylla (Diels) A.S.George. A key and distribution maps are provided for the six remaining varieties, two of which have conservation priority.
Two new species of Lepidosperma (Cyperaceae) occurring in the Perth area of Western Australia
BARRETT, R.L. AND WILSON, K.L., Nuytsia 23: 173–187 (2013)
Lepidosperma apricola R.L.Barrett is a new species from the Darling Range in Western Australia. An isolated population also occurs in Kings Park, in the heart of Perth. This species has been confused with L. leptostachyum Nees. in the past. Lepidosperma calcicola R.L.Barrett & K.L.Wilson is a new species from coastal dune systems on the west coast of Western Australia, which has been previously confused with a number of other taxa. It has been listed on FloraBase as Lepidosperma sp. Coastal Dunes (R.J. Cranfield 9963). Both are common species occurring in the Perth region of Western Australia (and more broadly in the South West Botanical Province) that have been unnamed up until now.
A revision of the south-western Australian genus Astartea (Myrtaceae: Chamelaucieae)
RYE, B.L., Nuytsia 23: 189–269 (2013)
Astartea DC. is a long-established, taxonomically difficult genus closely related to Cyathostemon Turcz. and Hypocalymma (Endl.) Endl. It is restricted to damp habitats of the South West Botanical Province of Western Australia. In this revision of the genus, 22 species are recognised, including 11 new species (A. cicatricosa Rye & Trudgen, A. decemcostata Rye, A. eobalta Rye, A. graniticola Rye & Trudgen, A. middletonii Rye, A. montana Rye, A. onycis Rye & Trudgen, A. schaueri Rye & Trudgen, A. reticulata Rye, A. transversa Rye and A. zephyra Rye & Trudgen) and one new subspecies (A. aspera Schauer subsp. riparia Rye). A presumed hybrid between A. arbuscula (R.Br. ex Benth.) Rye and A. corniculata Schauer is also described. Distinguishing characteristics, insect associations and other aspects of the biology of Astartea are discussed and illustrated.
Two new species of Westringia sect. Cephalowestringia (Lamiaceae: Westringieae) from the south-west of Western Australia
DAVIS, R.W. AND JOBSON, P., Nuytsia 23: 271–276 (2013)
Westringia fitzgeraldensis R.W.Davis & P.Jobson and W. ophioglossa R.W.Davis & P.Jobson are described here as new. A modification to the existing key for Westringia Sm. sect. Cephalowestringia Kuntze is provided to account for W. fitzgeraldensis and W. ophioglossa. Westringia fitzgeraldensis occurs in open mallee in the Fitzgerald River National Park and W. ophioglossa in mallee woodlands in the northern wheatbelt. A distribution map is provided.
Acacia gibsonii, a distinctive, rare new species of Acacia sect. Juliflorae (Fabaceae: Mimosoideae) from south-west Western Australia
MASLIN, B.R., Nuytsia 23: 277–281 (2013)
Acacia gibsonii Maslin, a new species with distinctively short, 3-nerved phyllodes and short spikes, and having affinities to A. incongesta R.S.Cowan & Maslin is described. The species is known from a geographically very restricted area of greenstone hills between Norseman and Hyden. It is currently listed by its phrase name, Acacia sp. Lake Johnson (N. Gibson & M. Lyons 1959), as Priority One under the Department of Environment and Conservation’s Conservation Codes for Western Australian Flora.
A revision of the species of Hypocalymma (Myrtaceae: Chamelaucieae) with smooth or colliculate seeds
RYE, B.L., WILSON, PAUL G. AND KEIGHERY, G.J., Nuytsia 23: 283–312 (2013)
Most members of the south-western Australian genus Hypocalymma (Endl.) Endl. have seeds with a shallowly to very deeply pitted testa. Two small groups of species, both revised here, differ in having a smooth or colliculate testa. Both groups occur in humid environments in the extreme south-west of Western Australia and show vegetative adaptations consistent with this habitat preference. The larger group, Hypocalymma sect. Cardiomyrtus Schauer, is reinstated. A new combination, H. minus (Strid & Keighery) Keighery, is made, bringing the total species recognised to five, and lectotypes are selected for two synonyms, H. boroniaceum F.Muell. ex Benth. and H. hypericifolium Benth. The other group is extremely rare, consisting of the possibly extinct species H. connatum Strid & Keighery, and a new species known from a single population, H. verticillare Rye. The latter group, named here as Hypocalymma sect. Verticilla Rye, is readily disitinguished by its 3-ridged young stems and consistently whorled leaves, and the new species is unusual in having extreme differences in the sizes of the anthers on different stamens within each flower. Molecular data indicate that sect. Verticilla is sister to sect. Cardiomyrtus. Evidence of taxonomic relationships is also presented from studies of hybridisation and insect associations.
A taxonomic update of Conostephium (Ericaceae: Styphelioideae: Styphelieae)
HISLOP, M., Nuytsia 23: 313–335 (2013)
Four new species from the Western Australian endemic genus Conostephium Benth., C. hortiorum Hislop, C. laeve Hislop, C. papillosum Hislop and C. prolatum Hislop are described, illustrated and their distributions mapped. Among these, C. prolatum has a very restricted distribution and is a conservation priority. A key to the 11 recognised species is provided as well as one to distinguish between the two putative generic taxa in the Conostephium clade. Lectotypes are designated for C. pendulum Benth., C. preissii Sond. and for the genus Conostephiopsis Stschegl. Taxonomic notes pertaining to C. drummondii (Stschegl.) C.A.Gardner, C. pendulum, C. preissii and C. roei Benth. are also included.
The Wollastonia/Melanthera/Wedelia generic complex (Asteraceae: Ecliptinae), with particular reference to Australia and Malesia
ORCHARD, A.E., Nuytsia 23: 337–466 (2013)
The generic limits of Wedelia Jacq., Melanthera Rohr, and Wollastonia DC. ex Decne., as currently recognised, are re-examined on the basis of comparative morphology, and a new classification recognising the first two genera in a restricted sense is proposed, with other taxa redistributed through nine genera. In this classification, Wedelia (including Aspilia Thouars) with c. 100 species, is restricted to the Americas and Africa. Melanthera is restricted to c. five species of the Caribbean basin and northern Andes. It is proposed that African species formerly in Melanthera be transferred to Lipotriche R.Br. and the following new combinations are made: L. scandens (Schum. & Thonn.) Orchard; L. scandens subsp. subsimplicifolia (Wild) Orchard; L. scandens subsp. dregei (DC.) Orchard; L. triternata (Klatt) Orchard; L. abyssinica (Sch.Bip. ex Rich.) Orchard; L. gambica (Hutch. & Dalziel) Orchard; L. pungens (Oliver & Hiern.) Orchard. The autonym L. scandens subsp. scandens is newly created. Echinocephalum Gardner of South America is resurrected, with a single species (E. latifolium Gardner). It is proposed that Wollastonia be retained as a genus distinct from Wedelia, Melanthera and Lipochaeta DC., with which it has been variously synonymised by recent authors. In Australia two species of Wollastonia are recognised, W. biflora (L.) DC. and W. uniflora (Willd.) Orchard. These species are keyed, described and illustrated. The Hawai‘ian species of Lipochaeta sect. Aphanopappus (Endl.) Benth. & Hook.f. are transferred to Wollastonia, and placement of Wollastonia lifuana (Hochr.) Fosb. of New Caledonia and Vanuatu, and the Asian species Wedelia prostrata Hemsl. in Wollastonia (as Wollastonia dentata) is confirmed. New combinations are made for Wollastonia biflora var. ryukyuensis (H.Koyama) Orchard, W. bryanii (Sherff) Orchard, W. dentata (H.Lév. & Vaniot) Orchard, W. fauriei (H.Lév.) Orchard, W. integrifolia (Nutt.) Orchard, W. kamolensis (O.Deg. & Sherff) Orchard, W. lavarum (Gaudich.) Orchard, W. micrantha (Nutt.) Orchard, W. micrantha subsp. exigua (O.Deg. & Sherff) Orchard, W. perdita (Sherff) Orchard, W. populifolia (Sherff) Orchard, W. remyi (A.Gray) Orchard, W. subcordata (A.Gray) Orchard, W. tenuifolia (A.Gray) Orchard, W. tenuis (O.Deg. & Sherff) Orchard, W. venosa (Sherff) Orchard, W. waimeaensis (H.St.John) Orchard and W. uniflora (Willd.) Orchard. The autonym W. micrantha subsp. micrantha is newly created. Lipochaeta DC. in Hawai‘i is restricted to the species with 4-lobed disc floret corollas, formerly treated as Lipochaeta sect. Lipochaeta. The Australian and New Guinean species formerly placed in Wedelia are transferred to two new genera: Apowollastonia Orchard, with eight species, including four new combinations (A. longipes (Klatt) Orchard, A. spilanthoides (F.Muell.) Orchard, A. stirlingii (Tate) Orchard and A. verbesinoides (Benth.) Orchard) and five new taxa (A. cylindrica Orchard, A. hamersleyensis Orchard, A. hibernica Orchard, A. major Orchard and A. stirlingii subsp. fontaliciana Orchard). The autonym A. stirlingii subsp. stirlingii is newly created, as is the genus Acunniana Orchard, with one species (A. procumbens (DC.) Orchard). In Malesia/Asia, two monotypic new genera are proposed, Indocypraea Orchard (with a single species, I. montana (Blume) Orchard, formerly Wedelia (Wollastonia) montana), and Quadribractea Orchard (with a single species, Q. moluccana (Blume) Orchard, formerly Wedelia moluccana). Five species related to the former Wedelia urticifolia (Blume) DC. are transferred to the new genus Lipoblepharis Orchard (L. urticifolia (Blume) Orchard, with two subspecies L. urticifolia subsp. urticifolia and subsp. hortorum Orchard, L. thailandica (Koyama) Orchard, L. asperrima (Decne.) Orchard, L. stenophylla (Merr.) Orchard and L. floribunda Orchard). Lectotypes are chosen for Verbesina urticifolia Blume, V. moluccana Blume, V. montana Blume, Buphthalmum australe Biehler (≡ Buphthalmum helianthoides sensu Forster), Wedelia spilanthoides F.Muell., Wedelia verbesinoides Benth. and Wedelia stirlingii Tate.
Distinguishing characters of Hemigenia rigida, a conservation significant species confused with H. pritzelii (Lamiaceae: Westringieae)
GUERIN, G.R., Nuytsia 23: 467–474 (2013)
Hemigenia rigida Benth. (sect. Homalochilus Benth.) is a species of high conservation concern from Western Australia’s Avon Wheatbelt known from three collections made 150 and 20 years apart. Hemigenia pritzelii S.Moore (also sect. Homalochilus), a more frequent species from the Jarrah Forest of south-west Western Australia, has been frequently confused with H. rigida and both were previously confused with H. ramosissima Benth. The mis-application of the name H. rigida to the distinct and more abundant species H. pritzelii has hampered recognition of the potentially dire conservation status of H. rigida. To resolve longstanding confusion, distinguishing characters are provided for H. pritzelii and H. rigida along with morphological descriptions, distribution maps and information on ecology. An interim key to the species of sect. Homalochilus is presented for context and to aid identification.
Hibbertia sericosepala (Dilleniaceae), a new species from Western Australia
THIELE, K.R., Nuytsia 23: 479–482 (2013)
Hibbertia sericosepala K.R.Thiele is described as new. Morphologically similar to H. helianthemoides (Turcz.) F.Muell. and H. huegelii (Endl.) F.Muell., H. sericosepala is distinctive in its combination of sepal and leaf indumentum, floral bract shape and anther and carpel number. It is endemic to the south-west of Western Australia.
An update to the taxonomy of some Western Australian genera of Myrtaceae tribe Chamelaucieae. 1. Calytrix
RYE, B.L., Nuytsia 23: 483–501 (2013)
Calytrix watsonii (F.Muell. & Tate) C.A.Gardner is reinstated and four species with conservation priority are described: C. hislopii Rye, C. patrickiae Rye, C. sagei Rye and C. viscida Rye. Keys are given for the species groups that include these taxa. The current study has eliminated about half of the informal names that have been in use for Western Australian members of the genus. Several species complexes that need further study are noted.
Typification and application of names in Drosera section Arachnopus
BARRETT, R.L. AND LOWRIE, A., Nuytsia 23: 527–541 (2013)
Taxonomic review of the Drosera indica L. (Droseraceae) complex requires the clarification of a number of published names. This paper is focussed on the application of names applying to taxa occurring in Australia. Two lectotypes are chosen and one neotype is designated for names historically listed as synonyms of D. indica. Drosera serpens Planch. and D. angustifolia F.Muell. are lectotypified. A neotype is selected for D. hexagynia Blanco as no original material is known. Drosera hexagynia is considered to be a synonym of D. indica. Drosera angustifolia and D. indica f. robusta F.M.Bailey are here considered to be synonyms of D. finlaysoniana Wall. ex. Arn. Drosera angustifolia var. purpuriflora F.Muell. ex Diels is an illegitimate name. Notes are provided on D. hartmeyerorum Schlauer, the only other named Australian taxon in this species complex. Characteristics of the seeds, anthers and glandular hairs are considered diagnostic at the species level. Illustrations of key identifying features and full descriptions of the Australian species are provided.
A baker’s dozen of new wattles highlights significant Acacia (Fabaceae: Mimosoideae) diversity and endemism in the north-west Kimberley region of Western Australia
MASLIN, B.R., BARRETT, M.D. AND BARRETT, R.L., Nuytsia 23: 543–587 (2013)
Thirteen new species of Acacia Mill. from the Kimberley region in northern Western Australia are described. These species are accommodated into three sections of the genus. Acacia sect. Juliflorae (Benth.) Maiden & Betche: A. anastomosa Maslin, M.D.Barrett & R.L.Barrett, A. camptocarpa Maslin, M.D.Barrett & R.L.Barrett, A. cyclocarpa Maslin, M.D.Barrett & R.L.Barrett, A. diastemata Maslin, M.D.Barrett & R.L.Barrett, A. phacelia Maslin, M.D.Barrett & R.L.Barrett and A. synantha Maslin, M.D.Barrett & R.L.Barrett. Acacia sect. Plurinerves (Benth.) Maiden & Betche: A. anserina Maslin, M.D.Barrett & R.L.Barrett, A. obtriangularis Maslin, M.D.Barrett & R.L.Barrett, A. orthotropica Maslin, M.D.Barrett & R.L.Barrett and A. perpusilla Maslin, M.D.Barrett & R.L.Barrett. Acacia sect. Lycopodiifoliae Pedley: A. claviseta Maslin, M.D.Barrett & R.L.Barrett, A. dimorpha Maslin, M.D.Barrett & R.L.Barrett and A. prolata Maslin, M.D.Barrett & R.L.Barrett. Notes are provided on A. gracillima Tindale (Acacia sect. Juliflorae) which provisionally includes a poorly known, distinctive entity in need of further taxonomic scrutiny. Except for A. claviseta, which extends to the Northern Territory, the new species are endemic to the Kimberley region. Eleven of the new species (all except A. camptocarpa and A. claviseta) are endemic to the high-rainfall area of the north-west Kimberley, highlighting significant levels of plant endemism in this region. A number of these species are geographically restricted (three are known only from the type) and all except A. prolata are treated as Priority taxa under the Department of Parks and Wildlife’s Conservation Codes for Western Australian Flora. Most of the new species are killed by fire and their distributions are restricted to rocky, presumably naturally fire-limiting sites.
Amanita lesueurii and A. wadjukiorum (Basidiomycota), two new species from Western Australia, and an expanded description of A. fibrillopes
DAVISON, E.M., MCGURK, L.E., BOUGHER, N.L., SYME, K. AND WATKIN, E.L.J., Nuytsia 23: 589–606 (2013)
Three species of Amanita Pers. are documented from Western Australia. Amanita lesueurii E.M.Davison is described from the mid-west region. It is distinguished by its small to medium fruiting bodies with a white pileus and white universal veil (both of which become vinaceous-buff or grey with age), white gills, short white stipe with a small obconic or turbinate bulb, white partial veil, amyloid, elongate to cylindrical spores, and no clamp connections. Amanita wadjukiorum E.M.Davison is described from the Perth metropolitan area. It has medium to large fruiting bodies with a cream pileus that ages milky coffee to snuff brown, a pale grey or buff universal veil that ages hazel to drab, cream gills, grey to buff stipe with a napiform or fusiform bulb, white to cream to vinaceous-buff partial veil that disappears with age, amyloid, ellipsoid to elongate spores and no clamp connections. Amanita fibrillopes O.K.Mill., which was previously only known from the type locality, is a widespread but misidentified species. It has small to large fruiting bodies with a pale peach to pale salmon pileus that rapidly ages cream, a white universal veil that rapidly ages buff or milky coffee, white gills that age buff, white or pale pink stipe with a spherical or obconic or tapered bulb, white or buff apical partial veil that disappears with age, inamyloid, ellipsoid to elongate spores and no clamp connections. A BLASTn search has shown that there are no exact matches of the nuclear ribosomal internal transcribed spacer (ITS) region of each species with those in GenBank.
Acacia equisetifolia, a rare, new species of Acacia sect. Lycopodiifoliae (Fabaceae: Mimosoideae) from the Top End of the Northern Territory
MASLIN, B.R. AND COWIE, I.D., Nuytsia 24: 1–5 (2014)
Acacia equisetifolia Maslin & Cowie, a new species known only from Kakadu National Park, Northern Territory, is described. The new species, formerly known by the phrase name Acacia sp. Graveside Gorge (V.J. Levitzke 806), is very closely related to A. hippuroides Heward ex Benth. which occurs about 1,000 km to the south-west, in the western Kimberley region of Western Australia. The main morphological features separating these two species are the nature of branchlet and peduncle indumentum and various pod attributes.
An update to the taxonomy of some Western Australian genera of Myrtaceae tribe Chamelaucieae. 2. Cyathostemon
TRUDGEN, MALCOLM E. AND RYE, B.L., Nuytsia 24: 7–16 (2014)
Three new species of Cyathostemon Turcz. are described, illustrated and mapped, and a key is given to the seven named species in the genus. The new species are C. divaricatus Trudgen & Rye, C. gracilis Trudgen & Rye and C. verrucosus Trudgen & Rye. This has reduced the number of taxa known by informal names to seven, most of which belong to a difficult species complex that needs a great deal more work to resolve.
Two new species of Calandrinia (Portulacaceae) from southern Western Australia

Two new species of Acacia (Fabaceae: Mimosoideae) with conservation significance from Banded Iron Formation ranges in the vicinity of Koolyanobbing, Western Australia
MASLIN, B.R., Nuytsia 24: 131–138 (2014)
Two geographically restricted species of Acacia Mill., A. haematites Maslin and A. shapelleae Maslin, from Banded Iron Formation (BIF) ranges in the south-west extremity of the arid zone of Western Australia are described. Acacia haematites occurs on the Koolyanobbing Range (close to the township of Koolyanobbing) while A. shapelleae occurs on the Helena and Aurora Range which is located about 40 km to the north of Koolyanobbing. Both these geographically restricted species occur in areas of mining interests and are therefore classified as Priority One under Department of Parks and Wildlife Conservation Codes for Western Australian Flora. The two new species belong to Acacia sect. Acacia and are allopatric with respect to their closest relatives (A. acuaria W.Fitzg. and A. glutinosissima Maiden & Blakely respectively) which are reasonably widespread in the central and northern wheatbelt region of the South West Botanical Province.
Miscellaneous new species of Acacia (Fabaceae: Mimosoideae) from south-west Western Australia
MASLIN, B.R., Nuytsia 24: 139–159 (2014)
Six new species endemic to south-west Western Australia are described. Three of the species belong to Acacia Mill. sect. Acacia (formerly sect. Phyllodineae DC.), namely, A. adjutrices Maslin (based on A. insolita subsp. efoliolata Maslin), A. coatesii Maslin and A. thieleana Maslin, one from Acacia sect. Juliflorae (Benth.) Maiden & Betche, namely, A. collegialis Maslin and two from Acacia sect. Plurinerves (Benth.) Maiden & Betche, namely, A. besleyi Maslin and A. fraternalis Maslin. Three of the species have conservation value under Department of Parks and Wildlife Conservation Codes for Western Australian Flora, namely, A. adjutrices (Priority Three), A. besleyi (Priority One) and A. coatesii (Priority One).
Four new species of Acacia (Fabaceae: Mimosoideae) with fasciculate phyllodes from south-west Western Australia

Four new species of Acacia Mill. sect. Acacia are described, namely, A. dilloniorum Maslin, A. keigheryi Maslin, A. kulinensis Maslin and A. parkerae Maslin. Acacia keigheryi, A. parkerae and A. kulinensis occur in the wheatbelt region of the South West Botanical Province; the first two were previously treated as informal variants of A. lullfitziorum Maslin to which they are related, with the latter more distantly related to these species. Acacia dilloniorum occurs in the adjacent Eremaean Botanical Province, in the south-west extremity of the arid zone; it is most closely related to A. kochii W.Fitzg. ex Ewart & Jean White and is not especially close to the other three new species described here. All four new species are classified as Priority taxa under Department of Parks and Wildlife Conservation Codes for Western Australian Flora. Notes are provided (under A. parkerae) on A. scabra Benth., a poorly known entity of uncertain taxonomic status that is known only from its type.
Spartothamnella canescens (Lamiaceae: Chloantheae), a new species from Western and Central Australia, with notes on the status of S. sp. Helena & Aurora Range
THIELE, K.R. AND SHEPHERD, K.A., Nuytsia 24: 177–185 (2014)
Morphological assessment of the informally named Spartothamnella sp. Helena & Aurora Range (P.G. Armstrong 155-109) shows it is not distinct from Western Australian populations of S. puberula (F.Muell.) Maiden & Betche. However, examination of S. puberula s. lat. shows that Western and Central Australian populations are morphologically distinct from typical populations in eastern Australia. Accordingly, S. canescens K.R.Thiele & K.A.Sheph. is newly described to accommodate these atypical populations. A revised description of S. puberula and a modified key for the genus are also provided.

An account of the reed triggerplants (Stylidium sect. Junceae: Stylidiaceae)
WEGE, J.A., Nuytsia 24: 215–247 (2014)
This taxonomic review of Stylidium sect. Junceae Mildbr. recognises eight species endemic to south-western Western Australia and presents a new circumscription for S. junceum R.Br., the original description of which was based on a mixed gathering comprising three distinct taxa. A lectotype is designated in order to fix the application of the name S. junceum to one of these, a species with a diminutive habit, pale creamy yellow to apricot-pink corolla lobes, and a column morphology that is unique within the genus. A neotype is designated for S. junceum subsp. brevius (E.Pritz.) Carlquist, which is not recognised as distinct. Stylidium scariosum DC. is reinstated and S. hesperium Wege, S. hygrophilum Wege, S. paludicola Wege and S. thryonides Wege described as new. Revised descriptions are provided for S. squamosotuberosum Carlquist and S. laciniatum C.A.Gardner, with S. junceum var. volubile F.Muell. lectotypified and placed into synonymy under the latter species. Descriptions, distribution maps, illustrations and photographs are supplied for each species, and an identification key provided. Stylidium hygrophilum has a highly localised distribution on the Blackwood Plateau south of Busselton and may warrant listing as Threatened. Stylidium paludicola, a species confined to swamps on the Swan Coastal Plain, is also listed as being of conservation concern, with targeted surveys required to better understand its conservation status.
A new subspecies of the threatened monocalypt Eucalyptus insularis (Myrtaceae) from Western Australia
NICOLLE, D., BROOKER, M.I.H. AND FRENCH, M.E., Nuytsia 24: 249–253 (2014)
Two subspecies are here recognised in the geographically rare and taxonomically isolated Eucalyptus insularis Brooker. Eucalyptus insularis subsp. insularis is known only from North Twin Peak Island in the Recherche Archipelago, about 90 km east-south-east of Esperance. Eucalyptus insularis subsp. continentalis D.Nicolle & Brooker subsp. nov. is known only from several small populations near Cape Le Grand on the mainland, about 25 km south-east of Esperance, and differs from the type subspecies in its low shrubby habit, smaller adult leaves with obscure tertiary venation and irregularly-shaped oil glands, more strongly pendulous inflorescences, and its generally smaller buds and fruits.

Gomphrena splendida R.L.Barrett & J.Palmer is described as a new species endemic to islands of the Bonaparte Archipelago in the north-west Kimberley region of Western Australia. This new species has a highly restricted distribution. It is unusual among the Australian species of Gomphrena L. in being a large, fleshy, perennial with very large flowers, giving this species significant horticultural potential in tropical areas. A modified key and images are presented.
Two new species of Phyllanthus from northern Australia and notes on Phyllanthus, Sauropus and Synostemon (Phyllanthaceae) in Western Australia
BARRETT, R.L. AND TELFORD, I.R.H., Nuytsia 26: 149–166 (2015)
Two new species of Phyllanthus L. are described, both included within P. subgen. Lysiandra F.Muell.; P. eremicus R.L.Barrett & I.Telford occurring in the Pilbara, Great Sandy Desert and southern Dampierland bioregions of Western Australia and the Tanami region of the Northern Territory, and P. hamelinii I.Telford & R.L.Barrett restricted to the Carnarvon bioregion, Western Australia. Both species have reasonably restricted or poorly known distributions and P. eremicus is of some conservation concern. Sauropus rigidulus (Müll.Arg.) Airy Shaw is formally recorded for Western Australia and a full description is provided. All of these taxa have previously been listed on Western Australia.s plant name census as phrase-named taxa. All three species are described and illustrated. Notes are made on the application of misapplied names and phrase-named taxa in Phyllanthus, Sauropus Blume and Synostemon F.Muell. in use in Western Australia.

Vigna triodiophila (Fabaceae: Phaseoleae), a new conservation-listed species from the Pilbara, Western Australia
HOLLAND, A.E. AND BUTCHER, R., Nuytsia 27: 77–83 (2016)
The new species described herein came to light during botanical surveys of the Burrup Peninsula and surrounds in 2000; it is geographically restricted to basalt rockpile habitats in the north-west of the Pilbara bioregion. Vigna triodiophila A.E.Holland & R.Butcher is diminutive in all its parts and can be readily distinguished from other Vigna Savi taxa in the Pilbara by its small (to 2.3(.3) cm long to 1.6(.2.1) cm wide), ovate to elliptic leaflets which lack lateral lobing. The species has a conservation listing of Priority Three in Western Australia.
Thismia tectipora (Thismiaceae) a new, unusual mitre-form species from tropical Australia
COWIE, I.D. AND LIDDLE, D.T., Nuytsia 27: 85–94 (2016)
A new tropical species, Thismia tectipora Cowie from Melville Island in the far north of the Northern Territory, Australia, is described and illustrated. The species is unique in the genus in having a thickened, fleshy, verrucose, cap-like mitre, the rim of which is reflexed to hide the pores in the upper perianth tube. It appears allied to taxa previously placed in Thismia Griff. sect. Sarcosiphon (Blume) Jonker, Geomitra Becc. and Scaphiophora Schltr. Available evidence suggests T. tectipora has a restricted distribution on Melville Island. Threats to the species, and its conservation status, are discussed.
An update to the taxonomy of some Western Australian genera of Myrtaceae tribe Chamelaucieae. 4. Malleostemon
RYE, B.L., Nuytsia 27: 103–120 (2016)
The following new species of Malleostemon J.W.Green are described: M. costatus Rye & Trudgen, M. microphyllus Rye & Trudgen, M. nephroideus Rye, M. nerrenensis Rye & Trudgen, M. pentagonus Rye & Trudgen, M. pustulatus Rye and M. uniflorus Rye. A new key is presented for the genus. Malleostemon sp. Kalbarri (L.A. Craven 7083) is reduced to synonymy under M. hursthousei (W.Fitzg.) J.W.Green and unnamed taxa that need further study are noted. Six of the new species have conservation priority.

DILLON, S.J. AND MARKEY, A.S., Nuytsia 27: 133–138 (2016)
A new species of Dysphania R.Br., D. congestiflora S.J.Dillon & A.S.Markey is described and an amendment to the most recent key of Dysphania is provided to include the new taxon.
Western Australian plant taxa not collected for more than 50 years
GIBSON, N., Nuytsia 27: 139–164 (2016)
An analysis of the Western Australian Herbarium collections generated a list of 29 endemic taxa last collected between 1888 and 1965, which are not currently on the Presumed Extinct schedule. On review, four of these taxa are not of immediate concern. The remaining 25 taxa are predominantly shrubs, generally known from very few collections, and are concentrated in heavily cleared bioregions, particularly the Avon Wheatbelt. Two taxa, Ptilotus sericostachyus subsp. roseus (Moq.) Benl and Darwinia divisa Keighery & N.G.Marchant, are recommended for immediate nomination as Presumed Extinct, while the remaining taxa will require further survey and/or taxonomic work to resolve their conservation status. Further survey will be challenging given the general lack of specific geographical and habitat information available for these taxa.
A taxonomic revision of Beaufortia (Myrtaceae: Melaleuceae)
BURBIDGE, A.A., Nuytsia 27: 165–202 (2016)
Beaufortia R.Br. (Myrtaceae) is endemic to the south-west of Western Australia and is almost confined to the South-West Botanical Province, with a few species extending a short distance into the Eremaean. Twenty-two species are recognised in this revision of the genus, including three new species: B. burbidgeae A.A.Burb., B. kwongkanicola A.A.Burb. and B. raggedensis A.A.Burb. Beaufortia puberula Turcz. is reinstated and B. interstans F.Muell. placed into synonymy under it. Lectotypes are selected for B. anisandra Schauer, B. dampieri A.Cunn., B. elegans Schauer, B. empetrifolia (Rchb.) Schauer, B. micrantha Schauer, B. micrantha var. puberula Benth., B. orbifolia F.Muell., B. schaueri Preiss ex Schauer, B. schaueri var. (?) atrorubens Benth., B. sparsa R.Br. and B. squarrosa Schauer.
Tetratheca butcheriana (Elaeocarpaceae), a new and rare species from the Pilbara bioregion of Western Australia
PERKINS, A.J., REIFFER, S. AND AJDUK, H., Nuytsia 27: 203–209 (2016)
A new species of Tetratheca Sm., discovered while performing flora surveys along banded ironstone cliffs north-west of Tom Price in 2015, is described. It is named T. butcheriana A.J.Perkins in honour of Ryonen Butcher, a botanical researcher and well-published taxonomic expert on Tetratheca in Western Australia. This species is one of two species of Tetratheca geographically restricted to the Pilbara bioregion, both of which are of conservation significance. A taxonomic description of T. butcheriana is provided, along with photographs and a list of diagnostic features to aid in identification.
New species of Leucopogon s. str. (Ericaceae: Epacridoideae: Styphelieae) from the Geraldton Sandplains
HISLOP, M., Nuytsia 27: 217–242 (2016)
Six new species of Leucopogon R.Br. (L. foliosus Hislop, L. grammatus Hislop, L. inflexus Hislop, L. prolatus Hislop, L. simulans Hislop and L. stenophyllus Hislop) are described, illustrated and their distributions mapped. Aspects of the morphology and taxonomy of the informal Northern Group of species are discussed and a comparison is made, in tabular form, between this group and two other informal groups, the L. pulchellus Sond. and L. carinatus R.Br. groups. A key to the species of Leucopogon s. str. from the Geraldton Sandplains bioregion is provided.
A new and rare species of Nymphoides (Menyanthaceae) from the North West of Western Australia
DAVIS, R.W., HAMMER, T.A. AND THIELE, K.R., Nuytsia 27: 245–252 (2016)
Nymphoides walshiae R.W.Davis & K.R.Thiele, a new and rare species of Nymphoides Ség., is described. This new species is geographically disjunct from other Nymphoides species, occurring in a small area of arid Western Australia near the Cape Range. A molecular phylogenetic analysis based on ITS sequences suggests that it occupies a phylogenetically isolated position sister to the largest clade in the genus. It lacks some of the more common features seen in the genus Nymphoides. A scanning electron microscope image displaying the seed surface and outline is provided.
New species of Eremophila (Scrophulariaceae): thirteen geographically restricted species from Western Australia
BUIRCHELL, B.J. AND BROWN, A.P., Nuytsia 27: 253–283 (2016)

Polycarpaea umbrosa R.L.Barrett (Caryophyllaceae), Ipomoea johnsoniana R.L.Barrett (Convolvulaceae) and Eriachne pindanica R.L.Barrett (Poaceae) are described as new species endemic to the Kimberley region of Western Australia. A revised description of Eriachne semiciliata Lazarides is presented. Polycarpaea umbrosa and Ipomoea johnsoniana both have conservation-listing as Priority One taxa. All new species are illustrated.
Allan Cunningham and the Boab (Adansonia gregorii; Bombaceae)
ORCHARD, A.E., Nuytsia 28: 1–9 (2017)
The Australian Boab, now known as Adansonia gregorii F.Muell. was first noticed botanically by Allan Cunningham during Phillip Parker Kingâs second survey voyage in 1819, and first collected by Cunningham in the following year at Careening Bay. Cunningham saw only fruiting material, and considered the tree to belong to the genus Capparis L., giving it the manuscript name C. gibbosa A.Cunn. He described but did not formally name the species in Kingâs Narrative of a Survey. The name was published with a valid description in Hewardâs biography of Cunningham in 1842. In the interim Cunningham had drafted a paper comparing his species with the African genus Adansonia Juss., but unfortunately never published it. Subsequently Mueller described the species again, as A. gregorii F.Muell., based on specimens collected near the Victoria and Fitzmaurice Rivers, and this name became accepted for the species. In 1995 Baum recognised that the two descriptions referred to the same taxon, and made the combination Adansonia gibbosa (A.Cunn.) Guymer ex D.Baum. A subsequent referral to the Spermatophyta Committee and General Committee resulted in the name C. gibbosa being rejected, on the grounds that âit seems unlikely thatâCunningham had any intention that this [Hewardâs] description should validate the name of a new species.â Recent rediscovery of Cunninghamâs draft paper shows that, on the contrary, Cunningham clearly believed that his name C. gibbosa was suitable for acceptance, and according to the practices of his day, should be published. That his premature death and subsequent unrecognised description of the species in Hewardâs paper resulted in his discovery going unacknowledged, and being overtaken by Muellerâs later description, is unfortunate, but now irreversible.
An examination of the Australian genus Xerochrysum (Asteraceae: Gnaphalieae)
WILSON, PAUL G., Nuytsia 28: 11–38 (2017)
In this partial revision of Xerochrysum Tzvelev the following taxa are described as new: X. alpinum Paul G.Wilson, X. boreale Paul G.Wilson, X. halmaturorum Paul G.Wilson and X. interiore Paul G.Wilson. Accounts of several published and unpublished species from north-east New South Wales and south-east Queensland that are currently recognised are omitted since these are being studied by other botanists; however, these taxa are included in the key to species provided here. Lectotypes are chosen for Helichrysum bracteatum var. viscosum DC., X. bicolor (Lindl.) R.J.Bayer and X. viscosum (Sieber ex Spreng.) R.J.Bayer.
An expanded circumscription and new infrageneric classification of Rinzia (Myrtaceae: Chamelaucieae)
RYE, B.L., Nuytsia 28: 39–93 (2017)
The circumscription of Rinzia Schauer (Myrtaceae tribe Chamelaucieae DC.) is enlarged to encompass species with varied stamen arrangement, filament width and seed morphology. This revision of Rinzia s. lat. is based on both morphological and molecular evidence, and establishes five sections within the genus, Discolora Rye, Mesostemon Rye, Polyandra Rye, Semasperma Rye and the typical section. All sections occur in Western Australia, with three of them endemic to the south-west, while sect. Polyandra also occurs in central Australia and sect. Semasperma also occurs in south-eastern Australia. Three new combinations are made for species previously included within Baeckea L., and the new name R. orientalis Rye is published for B. crassifolia Lindl. Baeckea crassifolia var. icosandra F.Muell. ex Benth. is raised to species rank as R. icosandra (F.Muell. ex Benth.) Rye. The other new combinations are R. ericaea (F.Muell. ex Benth.) Rye and R. polystemonea (F.Muell.) Rye. Four new Western Australian species are described as R. fimbriolata Rye & Trudgen, R. medifila Rye, R. torquata Rye & Trudgen and R. triplex Rye & Trudgen, and a new subspecies from Kangaroo Island, South Australia, as R. ericaea subsp. _insularis_Rye. Rinzia morrisonii Trudgen is reduced to synonymy under R. longifolia Turcz. Lectotypes are selected for Baeckea ericaea F.Muell. ex Benth. and R. morrisonii. Seven Western Australian species have conservation priority.
Five new species of Styphelia (Ericaceae: Epacridoideae: Stypheliae) from the Geraldton Sandplains, including notes on a new, expanded circumscription for the genus
HISLOP, M. AND PUENTE-LELIÈVRE, C., Nuytsia 28: 95–114 (2017)
Five new species of Styphelia Sm. (S. ciliosa Hislop & Puente-Lel., S. filamentosa Hislop & Puente-Lel., S. filifolia Hislop & Puente-Lel., S. longissima Hislop & Puente-Lel. and S. williamsiorum Hislop & Puente-Lel.) are described, illustrated and mapped. All were previously recognised by phrase names under Leucopogon R.Br., and occur in the Lesueur Sandplain subregion of the Geraldton Sandplains bioregion. There is discussion of the recent decision to greatly expand the circumscription of Styphelia to include the genera Coleanthera Stschegl., Croninia J.M.Powell, most species of Astroloma R.Br. and a large percentage of those previously treated as Leucopogon.
Taxonomic notes on Asterolasia (Rutaceae) in Western Australia to inform conservation
WEGE, J.A., Nuytsia 28: 141–146 (2017)
Following examination of collections at the Western Australian Herbarium, the Threatened species Asterolasia nivea (Paul G.Wilson) Paul G.Wilson is synonymised under A. grandiflora (Hook.) Benth. A revised description is provided for A. grandiflora, a geographically restricted species that will remain listed as Priority Four under Department of Parks and Wildlife Conservation Codes for Western Australian Flora despite its expanded circumscription. Asterolasia pallida Benth. subsp. hyalina Paul G.Wilson, a distinctive taxon previously only known from Dryandra State Forest, is raised to species level and A. sp. Kalgan River (S. Barrett 1522), which is listed as Threatened in Western Australia, is treated as synonymous. While the latter action greatly expands the known range of A. hyalina (Paul G.Wilson) Wege, this taxon retains its conservation ranking of Priority Two. A key to species of Asterolasia F.Muell. in Western Australia is provided.
Acacia nicholsonensis (Fabaceae), a new ‘Minni Ritchi’-barked species of Acacia sect. Juliflorae from the Gulf of Carpentaria region of Northern Australia
CUFF, N.J. AND COWIE, I.D., Nuytsia 28: 147–158 (2017)
Acacia nicholsonensis Cuff is described as a new species of Acacia Mill. sect. Juliflorae (Benth.) Maiden & Betche. Acacia nicholsonensis is currently only known from the upper Nicholson River catchment in the far east of the Northern Territory where it is restricted to the levees and banks of major river channels. A key to the ‘Minni Ritchi’-barked Acacia species of the Top End of the Northern Territory and adjacent regions of tropical northern Australia is presented. The conservation status and ecology of the new species are discussed.
New lectotypes and synonyms in the Western Australian genus Scholtzia (Myrtaceae: Chamelaucieae)

Neotypification and redescription of Amanita preissii (Basidiomycota), and reconsideration of the status of A. griseibrunnea
DAVISON, E.M., GIUSTINIANO, D., MCGURK, L.E., WATKIN, E.L.J. AND BOUGHER, N.L., Nuytsia 28: 193–204 (2017)
Amanita preissii (Fr.) Sacc. is redescribed. Re-examination of collections of A. griseibrunnea O.K.Mill. show that they do not differ significantly from A. preissii and the two species are combined. This species is common in the Perth IBRA subregion. Sequence data from the nuclear ribosomal internal transcribed spacer (ITS) region, 28S nuclear ribosomal large subunit rRNA (28S) region, RNA polymerase II (RPB2) region, β-tubulin region and translation elongation factor 1-α (EF1-α) region have been deposited in GenBank.
Revision of the south-western Australian genus Anticoryne (Myrtaceae: Chamelaucieae)
RYE, B.L., Nuytsia 28: 205–215 (2017)
Anticoryne Turcz. comprises three species occurring in a relatively small portion of south-western Australia. Stamen morphology is of diagnostic importance for the genus, as is its very dark seed colour. In this revision of the genus, the new species A. melanosperma Rye is named and a lectotype is selected for A. ovalifolia (F.Muell.) Rye. All species have conservation priority.
Calandrinia holtumii (Portulacaceae), a new and unusual species from arid Western Australia
OBBENS, F.J., HANCOCK, L.P., EDWARDS, E. AND THIELE, K.R., Nuytsia 28: 217–223 (2017)
A new species of Calandrinia Kunth., C. holtumii Obbens & L.P.Hancock, from arid Western Australia is described and mapped. At this stage, the sectional placement for C. holtumii is uncertain. It has several anomalous morphological characters not previously recorded within the genus and has recently been shown to exhibit a stronger form of Crassulacean Acid Metabolism (CAM) than any other Australian species of Calandrinia.
Stylidium miscellany 3: a synopsis of Robert Brown’s Stylidiaceae types and occasional notes on associated names
WEGE, J.A., Nuytsia 28: 229–246 (2017)

(= S. tenerum Spreng.) and S. violaceum R.Br. Stylidium robustum Sond. is newly synonymised under S. diversifolium and lectotypes are selected for two additional synonyms of this species, S. marginatum Sond. and S. pruinosum Sond. Stylidium pilosum is lectotypified and a neotype designated for S. pilosum var. brevius E.Pritz. Comments on the uncertain circumscription of S. armeria (Labill.) Labill. (of which S. melastachys R.Br. is a synonym) are provided.
Hibbertia striata, a new combination for a long-overlooked Western Australian species, and inclusion of H. pachyrrhiza in H. huegelii
THIELE, K.R., Nuytsia 28: 247–253 (2017)
The common and widespread species Hibbertia huegelii (Endl.) F.Muell. comprises two distinct taxa, one of which matches the type of Candollea striata Steud., which is here recombined as Hibbertia striata (Steud.) K.R.Thiele. Hibbertia pachyrrhiza Steud. is reduced to a synonym of H. huegelii s. str. Descriptions and distribution maps are provided for both accepted species.
Nomenclatural changes in Chenopodium (incl. Rhagodia) (Chenopodiaceae), with considerations on relationships of some Australian taxa and their possible Eurasian relatives
MOSYAKIN, S.L. AND IAMONICO, D., Nuytsia 28: 255–271 (2017)
Following recent molecular phylogenetic results, species earlier placed in Rhagodia R.Br. were transferred to Chenopodium L. (Chenopodiaceae). However, three new species-level combinations proposed were later homonyms and thus illegitimate under ICN Art. 53.1. The new name C. wilsonii S.Fuentes, Borsch & Uotila [= C. crassifolium (R.Br.) S.Fuentes & Borsch, comb. illeg.] has been already proposed for one of these species. We propose here two new replacement names, C. robertianum Iamonico & Mosyakin, nom. nov. [≡ R. hastata R.Br. ≡ C. hastatum (R.Br.) S.Fuentes & Borsch, comb. illeg.] and C. benthamii Iamonico & Mosyakin, nom. nov. [≡ R. crassifolia R.Br. var. latifolia Benth. ≡ C. latifolium (Benth.) S.Fuentes & Borsch, comb. illeg.]. One new combination, C. benthamii subsp. rectum (Paul G.Wilson) Iamonico & Mosyakin, comb. nov. [≡ R. latifolia (Benth.) Paul G.Wilson subsp. recta Paul G.Wilson] is also validated. Indications of ‘holotypes’ of R. hastata by Scott and R. crassifolia var. latifolia by Wilson are corrected to lectotypes according to ICN Art. 9.9. Possible relationships and biogeographical links of Australian species earlier placed in Rhagodia, Einadia Raf., and Australian endemic groups of Chenopodium (sections Auricoma Aellen, Desertorum Paul G.Wilson, Rhagodioides Benth. etc.) with Eurasian taxa of Chenopodium (in particular, C. sect. Acuminata Ignatov, C. frutescens C.A.Mey., and newly recognised C. sect. Vulvaria (Standl.) Iamonico & Mosyakin, comb. nov.) are also discussed. Earlier predictions of these possible relationships are emphasised and new predictions are made, which should be tested by molecular phylogenetic and other methods.
A revision of the Lasiopetalum floribundum group (Malvaceae), including recognition of four new species
SHEPHERD, K.A. AND WILKINS, C.F., Nuytsia 28: 273–298 (2017)
This revision focuses on Lasiopetalum floribundum Benth. and six morphologically allied Western Australian species. This group is characterised by loose dichasial or monochasial inflorescences comprising small, pink or white flowers subtended by a narrow, non-petaloid, epicalyx bract and having reflexed, stellate hairs on the style. Three new species of conservation significance from east and north of Perth are named as L. caroliae K.A.Sheph., L. rutilans K.A.Sheph. & C.F.Wilkins and L. moullean K.A.Sheph. & C.F.Wilkins, and a new species from the Margaret River region, L. occidentale K.A.Sheph. & C.F.Wilkins, is also recognised. Revised descriptions are provided for L. floribundum (which is lectotypified), L. glabratum Paust and the Threatened species L. pterocarpum E.M.Benn. & K.A.Sheph. A key to the group is included along with images and distribution maps.
A taxonomic update of Brachyloma (Ericaceae: Epacridoideae: Styphelieae) in Western Australia
HISLOP, M. AND CRANFIELD, R.J., Nuytsia 28: 303–316 (2017)
Three new Western Australian species of Brachyloma Sond., B. djerral Cranfield & Hislop, B. elusum Hislop & Cranfield and B. pirara Cranfield & Hislop, are described and illustrated. All three are of conservation concern. A new combination, B. geissoloma (F.Muell.) Cranfield, is published to replace the illegitimate name B. concolor F.Muell. ex Benth. The following manuscript names are synonymised: B. ericoides subsp. occidentale Cranfield ms, B. geissoloma subsp. collinum Cranfield ms, B. geissoloma subsp. ovatum Cranfield ms and B. moolya Cranfield ms under B. geissoloma; B. jillup Cranfield ms, B. preissii subsp. lanceolatum Cranfield ms, B. preissii subsp. obtusifolium Cranfield ms and B. tamminense Cranfield ms under B. preissii Sond. A lectotype is designated for B. preissii. An updated key to the Western Australian species of Brachyloma is provided.
A revision of the Calytrix acutifolia complex (Myrtaceae: Chamelaucieae)
NGE, F.J., KEIGHERY, G.J. AND THIELE, K.R., Nuytsia 28: 321–337 (2017)
In this taxonomic review of the Calytrix acutifolia (Lindl.) Craven species complex we recognise four species, one of which (C. retrorsifolia Nge & Keighery) is described as new. Lhotskya hirta Regel is recombined into Calytrix Labill. as C. hirta (Regel)Nge & K.R.Thiele, while L. scabra Turcz. is recombined as C. cravenii Nge & K.R.Thiele. Calytrix acutifolia s. str. is recircumscribed as the fourth member of the complex.
A taxonomic revision of the basin-like rosetted triggerplants of the Stylidium piliferum complex (Stylidiaceae) from south-western Australia
LOWRIE, A. AND KENNEALLY, K.F., Nuytsia 28: 339–382 (2017)
A taxonomic revision of the basin-like rosetted triggerplants of the Stylidium piliferum R.Br. complex (Stylidiaceae) from the south-west of Western Australia is presented. Fifteen species are recognised including the new species S. amphora Lowrie & Kenneally, S. bindoon Lowrie & Kenneally, S. monticola Lowrie & Kenneally, S. nitidum Lowrie & Kenneally, S. ponticulus Lowrie & Kenneally, S. salmoneum Lowrie & Kenneally, S. strigosum Lowrie & Kenneally and S. vinosum Lowrie & Kenneally. Revised descriptions are provided for seven named species: S. bicolor Lindl., S. ciliatum Lindl., S. ferricola Wege & Keighery, S. hispidum Lindl., S. miniatum Mildbr., S. piliferum and S. pubigerum Sond. All species are illustrated and a key is also provided.
The Australian plant collections of Diels and Pritzel 1900–1902
GIBSON, N., Nuytsia 29: 25–56 (2018)
Ludwig Diels and Ernst Pritzel undertook a two year collecting trip between 1900–1902 that included Western Australia, the eastern seaboard and New Zealand. Material collected on this expedition resulted in publication of over 300 new taxa. The loss of many of Diels’ types during a bombing raid on Berlin in 1943 has resulted in a need to designate neotypes for many of these names. The history and possible nomenclatural significance of the joint collections they donated to the Western Australian Museum in 1901 is examined to assist identification of candidate material.
An update to the taxonomy of some Western Australian genera of Myrtaceae tribe Chamelaucieae: 5. Hysterobaeckea
RYE, B.L., Nuytsia 29: 75–107 (2018)
Eight new species belonging to Hysterobaeckea (Nied.) Rye are described: H. cornuta Rye, H. glandulosa Rye, H. graniticola Rye, H. longipes Rye, H. occlusa Rye, H. petraea Rye, H. pterocera Rye and H. setifera Rye. Hysterobaeckea ochropetala (F.Muell.) Rye is broadly delimited and two new subspecies are described as subsp. cometes Rye and subsp. reliqua Rye. The new subspecies H. setifera subsp. meridionalis Rye is also described. Six of the new taxa have conservation priority. A key is given for the named members of the genus.
Eucalyptus revelata, a rare new species related to E. mooreana (Myrtaceae) from the Kimberley region of Western Australia
NICOLLE, D. AND BARRETT, R.L., Nuytsia 29: 109–118 (2018)
Two variants of E. mooreana W.Fitzg. s. lat., a rare species from the Kimberley region of Western Australia, are found to be specifically distinct. A revised description of E. mooreana is provided and E. revelata D.Nicolle & R.L.Barrett is described to accommodate plants with a more sprawling habit, less powdery and less uniformly-coloured bark, non- or weakly-pruinose features, green leaves and generally smaller fruits. Both E. mooreana and E. revelata are restricted to steep rocky slopes and mountain ridges in the higher parts of the King Leopold Ranges. A key to the terminal taxa of Eucalyptus ser. Subexsertae (Benth.) Blakely (the ‘northern white gums’) is provided. Authorship of the name E. mooreana is discussed and attributed to W.V. Fitzgerald rather than J.H. Maiden. A new lectotype is designated as the previous designation was found to be ineffective.
By their fruit you will recognise them: species notes and typifications in Western Australian species of Opercularia (Rubiaceae: Anthosperminae)
MARKEY, A.S., Nuytsia 29: 119–140 (2018)
An examination of herbarium collections, type material and reference to original species descriptions has found that several species names of Opercularia Gaertn. have been misapplied in Western Australia. This nomenclatural confusion stems from a combination of missing types, a lack of reference to either types or correctly identified specimens, and no recent revisions of the genus. Previously presumed to be extinct, O. acolytantha Diels is neotypified and discussed here as an extant species endemic to the Mallee and Esperance bioregions of Western Australia. Opercularia hirsuta Benth. is found to be a far rarer species than previously thought, with no material matching the type collected since the 1860s. Opercularia nubicola A.S.Markey is described as a new species with affinities to O. aspera Gaertn. Opercularia rubioides Juss. is reduced to synonymy with O. aspera,which is excluded from Western Australia. Opercularia scabrida Schltdl. is also excluded from Western Australia. This paper provides updated notes, illustrations and a key to Western Australian species of Opercularia. Characteristics of the infructescence, fruits and seed are diagnostic for these species and are illustrated here for this purpose.
A taxonomic revision of species with a petaloid epicalyx bract allied to Lasiopetalum bracteatum (Malvaceae: Byttnerioideae)
SHEPHERD, K.A. AND WILKINS, C.F., Nuytsia 29: 161–179 (2018)
This treatment focuses on an informal group of six species where Lasiopetalum bracteatum (Endl.) Benth., L. membranaceum (Steud.) Benth. and L. molle Benth. are revised and lectotypified, an updated description of the Threatened species L. rotundifolium Paust is provided, and two new related species of conservation concern, L. decoratum K.A.Sheph. & C.F.Wilkins and L. rupicola K.A.Sheph. & C.F.Wilkins, are described. Images and distribution maps are included.
Typification of Lasiopetalum and an interim key to the Western Australian species of the genus (Malvaceae: Byttnerioideae)
SHEPHERD, K.A. AND WILKINS, C.F., Nuytsia 29: 181–192 (2018)
Lasiopetalum ferrugineum Sm. is lectotypified and selected as the type for Lasiopetalum Sm. Notes on the variation within L. rosmarinifolium (Turcz.) Benth. are provided, with L. rosmarinifolium var. latifolium (Turcz.) Benth. and L. sp. Kukerin (C.A. Gardner 13646) treated as synonyms. A preliminary key to the species of Western Australian Lasiopetalum is also presented.
Three new perennial species of Calandrinia (Montiaceae) from southern Western Australia
OBBENS, F.J., Nuytsia 29: 193–204 (2018)
Three new species of Calandrinia Kunth. sect. Pseudodianthoideae Poelln. from Western Australia (C. quartzitica Obbens, C. lefroyensis Obbens and C. wilsonii Obbens) are described and illustrated. All occur in the south-west, where there is only one other perennial species known to date.
Making it official—formal description of two orange-flowered Tephrosia (Fabaceae: Millettieae) species from north-west Western Australia
BUTCHER, R., Nuytsia 29: 251–267 (2018)
Two long-standing manuscript names in Tephrosia Pers. are herein formalised as T. densa (Benth.) Pedley ex R.Butcher and T. gardneri Pedley ex R.Butcher, and their various informal names synonymised. Full descriptions and images are provided for both these north-west Western Australian species and their histories and affinities are discussed.
Triodia pisoliticola (Poaceae), a new species from the Pilbara region, Western Australia, and a description for T. sp. Mt Ella (M.E. Trudgen MET 12739)
BARRETT, M.D. AND TRUDGEN, MALCOLM E., Nuytsia 29: 271–281 (2018)
The genus Triodia R.Br. is currently undergoing taxonomic revision in the light of intensive botanical survey in remote Australia and molecular phylogenetic data. Several Triodia species have been known by phrase names in Western Australia for about 20 years. This paper deals with two of these names, Triodia sp. Mt Ella (M.E. Trudgen 12739) and T. sp. Robe River (M.E. Trudgen et al. MET 12367), that were first recognised as distinct taxa by one of us. Both species are ‘soft’ spinifexes with awned lemmas, and are known only from the Pilbara region in Western Australia. Triodia sp. Robe River is formally described as T. pisoliticola Trudgen & M.D.Barrett. This species is restricted to the western part of the Pilbara bioregion and has flowers morphologically similar to T. melvillei (C.E.Hubb.) Lazarides. Triodia sp. Mt Ella has floral parts morphologically similar to T. bitextura Lazarides; a full description of this entity is given, but it is not formally named pending further revision of the T. bitextura complex across northern Australia. Both taxa are currently given a conservation ranking of Priority Three. Both taxa are illustrated, and diagnostic character combinations are given to allow discrimination from all other Pilbara Triodia species.
An update to the taxonomy of the Western Australian genera of the Myrtaceae tribe Chamelaucieae. 6. Scholtzia
RYE, B.L., Nuytsia 30: 33–86 (2019)
Twenty five new species and five new subspecies of Scholtzia are described: S. bellairsiorum Rye, S. brevistylis Rye, S. brevistylis subsp. prowaka Rye, S. calcicola Rye, S. chapmanii Trudgen ex Rye, S. cordata Trudgen ex Rye, S. corrugata Rye, S. denticulata Rye, S. halophila Rye, S. halophila subsp. meridionalis Rye, S. halophila subsp. mortlockensis Rye, S. inaequalis Rye, S. laciniata Rye, S. longipedata Rye, S. longipedata subsp. procera Rye, S. multiflora Rye, S. oleosa Rye, S. peltigera Rye, S. pentamera Rye, S. pentamera subsp. collina Rye, S. prostrata Rye, S. quindecim Rye, S. recurva Rye, S. subsessilis Rye, S. tenuissima Rye, S. thinicola Rye, S. trilocularis Rye, S. truncata Rye, S. uniflora Rye and S. uniovulata Rye. Scholtzia sp. Shark Bay (M.E. Trudgen 7429) is reduced to synonymy under S. capitata Benth. and most of the other phrase names in the genus are treated as synonyms of the above new taxa. A key is given to aid the identification of approximately 40 species and subspecies. Most taxa have conservation priority.
A revision of the tiurndins (Tribonanthes, Haemodoraceae)
HICKMAN, E.J., Nuytsia 30: 87–154 (2019)
The tiurndins (Tribonanthes Endl.) comprise a small taxonomically challenging genus of geophytes endemic to the Southwest Australian Floristic Region. Six named and one undescribed species of Tribonanthes are recognised in recent literature. Tribonanthes poses the most difficult taxonomic problems remaining for the Haemodoraceae in Western Australia. It is a genus where herbarium studies alone are insufficient to delineate taxa. A knowledge of variation in wild living material has proved essential to resolve taxonomic difficulties in the tiurndins. This revision recognises and comprehensively illustrates living plants of the 12 recognised species, four of which are new (T. elongata E.J.Hickman & Hopper, T. keigheryi E.J.Hickman & Hopper, T. monantha E.J.Hickman & Hopper and T. porphyrea E.J.Hickman & Hopper). Tribonanthes variabilis Lindl. and T. uniflora Lindl. are reinstated. Morphological and molecular data also support the recognition of three new subgenera: subg. Tribonanthes, subg. Salina E.J.Hickman & Hopper and subg. Boya E.J.Hickman & Hopper. Botanical illustration, especially of internal floral morphology, has revealed several previously unrecorded characters that help diagnose the species of Tribonanthes.
A taxonomic review of the Styphelia xerophylla group (Ericaceae: Epacridoideae: Styphelieae)
HISLOP, M. AND PUENTE-LELIÈVRE, C., Nuytsia 30: 155–175 (2019)
Species belonging to the Western Australian S. xerophylla (DC.) F.Muell. group (or Group IX) are described and illustrated. The treatment includes two species published in the nineteenth century, S. xerophylla and S. stomarrhena (Sond.) Sleumer, together with four new species, S. angustiflora Hislop & Puente-Lel., S. cernua Hislop & Puente-Lel., S. disjuncta Hislop & Puente-Lel. and S. sulcata Hislop & Puente-Lel. A seventh member of the group, S. longissima Hislop & Puente-Lel., was described in a recent paper and is not treated again here. The morphological attributes of the group are outlined and a key to species provided.
Elionurus tylophorus (Poaceae: Paniceae: Andropogoneae), a new species from the Kimberley region of Western Australia
BARRETT, M.D. AND HANDASYDE, T., Nuytsia 30: 177–194 (2019)
A new annual species, Elionurus tylophorus M.D.Barrett & T.Handasyde is described in the genus Elionurus Willd. of the grass tribe Andropogoneae. It differs from all previously described Elionurus species in having keels of the lower fertile glumes ornamented with projections, these often terminated by minute solitary bristles, rather than regular cilia lacking projections, or with projections terminated by hair-tufts in other species. It differs further from E. citreus (R.Br.) Benth. and E. purpureus E.J.Thomps., the only other Australian Elionurus, in having strongly developed fertile glume nerves, rachilla longer and lacking a wing, and presence of lemmas and anthers in the pedicellate spikelet. Elionurus tylophorus is currently known from a single location in the King Leopold Ranges in the central Kimberley region, and has conservation significance. A primary division of Elionurus into two clades is hypothesised based on a preliminary chloroplast gene phylogeny and two morphological synapomorphies, presence of tufted glume hairs and oil streaks.
Two new Western Australian species segregated from Banksia densa (Proteaceae)
THIELE, K.R., Nuytsia 30: 203–214 (2019)
Banksia densa A.R.Mast & K.R.Thiele has until now been regarded as a widespread species in the Western Australian wheatbelt, comprising a widespread nominate variety and a geographically more restricted variety in the southern part of its range (var. parva (A.S.George) A.R.Mast & K.R.Thiele). An informally recognised morphological variant, which matches the type of the species, is geographically restricted to an area on the edge of the species range in the immediate vicinity of Corrigin. Morphological assessment shows that the Corrigin form differs significantly in leaf morphology from the remainder of the species and comprises the true B. densa. The widespread taxon previously referred to as B. densa var. densa, and the southern var. parva, are here raised to species rank as B. zygocephala K.R.Thiele sp. nov. and B. parva (A.S.George) K.R.Thiele comb. et stat. nov. respectively.
Additions to Eremophila (Scrophulariaceae)
CHINNOCK, R.J., Nuytsia 30: 215–219 (2019)
One new species of Eremophila R.Br., E. waitii Chinnock, is described and one subspecies of E. glabra (R.Br.) Ostenf., E.glabra subsp. verrucosa Chinnock, is raised to species level and recognised herein as E. viridissima Chinnock.
Triodia veniciae (Poaceae), a new species from the Pilbara region, Western Australia
BARRETT, M.D., Nuytsia 30: 221–228 (2019)
The Australian hummock grass genus Triodia R.Br. is currently undergoing taxonomic revision following increased botanical survey in remote Australia. This paper describes a recently discovered species ‘soft’ Triodia from the Pilbara region, T. veniciae M.D.Barrett. The lemma lobes of the new species are narrow and produced into a short awnlet, intermediate between the old, and now united, generic concepts of Plectrachne Henrard with awned lemmas and Triodia with lobed lemmas. Triodia veniciae M.D.Barrett is only known from rocky shale slopes of the eastern Chichester Range, and has priority conservation status. Diagnostic character combinations for T. veniciae are given to allow discrimination from all other Triodia.
Calandrinia monosperma and C. uncinella (Montiaceae), two new indehiscent species from Western Australia
OBBENS, F.J., Nuytsia 30: 237–245 (2019)
Two unique indehiscent species of Calandrinia Kunth. from Western Australia are described and mapped and their affinities are discussed with regards to a recent phylogeny for Australian Calandrinia.
Nomenclatural updates and a new species of annual Hydrocotyle (Araliaceae) from Western Australia
PERKINS, A.J., Nuytsia 30: 253–277 (2019)
This treatment deals with five annual Western Australian species of Hydrocotyle L. and is based on the outcomes of a recent molecular phylogenetic study combined with a re-evaluation of schizocarp morphology. Hydrocotyle perplexa A.J.Perkins is newly named, H. intertexta R.Br ex A.Rich. is reinstated, and the three other species covered are H. glochidiata Benth., H. scutellifera Benth. and H. tetragonocarpa Bunge. Three taxa are placed in synonymy: H. blepharocarpa F.Muell. under H. scutellifera, H. pilifera Turcz. under H. intertexta and H. hispidula var. tenella Benth. under H. perplexa. Lectotypes are selected for five of these names, and full descriptions, distribution maps and images are provided for all five species. Details of the history of recognition of these species, and a series of misapplications of names, are also given.
Update on generic and specific nomenclature in Paracaleana (Drakaeinae), Caladeniinae and a new name in Caladenia (Orchidaceae)
HOPPER, STEPHEN D. AND BROWN, A.P., Nuytsia 30: 279–285 (2019)
Accepting guidance on stability of names from the Preamble to successive International Codes of Botanical Nomenclature, and in the interests of minimizing name changes consistent with present scientific evidence, we propose that the Australian orchid genus Paracaleana should be maintained as a distinct genus from Caleana, and that Caladenia remains best recognised as distinct from Cyanicula, Ericksonella, Pheladenia, Glossodia and Elythranthera. Recent proposals to lump these genera unnecessarily creates new names in the absence of compelling new scientific evidence to do so. A new name, Caladenia varians Hopper & A.P.Br., is erected to replace C. vulgata Hopper & A.P.Br. The type of C. vulgata matches Caladenia incensum Hopper & A.P.Br., and the former species is therefore rendered synonymous with the latter.
The Hibbertia polystachya–H. spicata (Dilleniaceae) species group in Western Australia
THIELE, K.R., Nuytsia 30: 291–308 (2019)
Hibbertia spicata F.Muell. and H. polystachya Benth. are widespread in south-western Western Australia, where they are unique in Hibbertia Andrews in having flowers in a cincinnus rather than solitary. The boundary between these two species has been problematic, as they mostly differ in the composition and density of indumentum on their sepals and leaves. Close study has revealed that H. polystachya is widespread and taxonomically relatively straightforward, while H. spicata sens. lat. comprises six distinctive, readily resolvable species (including H. leptotheca (J.R.Wheeler) K.R.Thiele comb. et stat. nov., previously H. spicata subsp. leptotheca J.R.Wheeler) differing in leaf and sepal indumentum, number of flowers in the cincinnus, floral bract shapes, stamen number, and number and arrangement of staminodes. New species described here are H. capensis K.R.Thiele sp. nov., H. asterella K.R.Thiele sp. nov. and H. subglabra K.R.Thiele sp. nov. The new name H. prolata K.R.Thiele is provided for a widespread taxon based on Hemistephus linearis J.Drumm. ex Harv. With these species removed, H. spicata is recircumscribed and is now more restricted in distribution.
A new name, clarification of synonymy, and a new subspecies for Isopogon (Proteaceae) in Western Australia
RYE, B.L. AND MACFARLANE, T.D., Nuytsia 30: 309–316 (2019)
Isopogon drummondii Benth. nom. illeg. is lectotypified and replaced by the new name I. autumnalis Rye & T.Macfarlane while I. drummondii Hügel ex Jacques is recognised as a probable synonym of I. sphaerocephalus Lindl. The new subspecies I. sphaerocephalus subsp. lesueurensis Rye is described.
Circumscription of Chamelaucium (Myrtaceae: Chamelaucieae), with validation of six species names and two new combinations
MARCHANT, N.G., Nuytsia 30: 317–334 (2019)
An updated description of the genus Chamelaucium Desf. compiled from all currently recognised formal and informal taxa is presented to establish the status of Chamelaucium at generic level within the Myrtaceae, tribe Chamelaucieae. Descriptions are provided for C. erythrochlorum N.G.Marchant, C. floriferum N.G.Marchant, and its two subspecies, C. lullfitzii N.G.Marchant, C. orarium N.G.Marchant, C. roycei N.G.Marchant, and C. xanthocladum N.G.Marchant. New combinations are made and descriptions provided for C. forrestii (F.Muell.) N.G.Marchant, and C. repens (A.S.George) N.G.Marchant. Precise localities for all taxa have been withheld for conservation reasons.
Two new, orange-flowered Tephrosia (Fabaceae: Millettieae) species from the Kimberley region, in Western Australia’s monsoon tropics
BUTCHER, R., Nuytsia 32: 39–50 (2021)
Ongoing taxonomic revision of Tephrosia Pers. in Australia is continuing to identify new taxa from study of existing herbarium collections as well as new material gathered from remote and under-collected areas. The Kimberley region of Western Australia is recognised for its biodiversity and endemism, but the recognition of new species is hampered by its inaccessibility, especially to areas of relief with complex microhabitats and refugia. It is from these areas that many recently described species, from across the Western Australian flora, have been collected. This paper describes and illustrates two new, poorly known, orange-flowered species of Tephrosia from the Kimberley region: T. cowiei R.Butcher, a close ally of the Northern Territory’s T. bifacialis Cowie, and T. funicularis R.Butcher, a distinctive new species from sandstone habitats.
Redefinition of Tephrosia supina (Fabaceae: Millettiae), a north-west Western Australian endemic, and description of two similar species
BUTCHER, R. AND COWIE, I.D., Nuytsia 32: 67–83 (2021)
The application of the name Tephrosia supina Domin is clarified herein, with this species determined as being a north-west Western Australian endemic subshrub with pink-purple flowers; T. supina s. str. is differentiated from two similar taxa, which also occur in the Northern Territory and Queensland. These are described herein as T. insolens R.Butcher & Cowie and T. lithosperma R.Butcher & Cowie, and T. supina is lectotypified. Full descriptions and images are provided for these three species and their histories and affinities are discussed.
Rubinoboletus phaseolisporus (Boletaceae) from Western Australia is a Tylopilus with bean-shaped spores
OSMUNDSON, T.W., BOUGHER, N.L., ROBINSON, R.M. AND HALLING, R.E., Nuytsia 32: 87–97 (2021)
The bolete genus name Rubinoboletus Pilát & Dermek has been misapplied in the past to include taxa belonging to several genera including Tylopilus P.Karst. In this study, we provide morphological and molecular phylogenetic justification for alignment of Rubinoboletus phaseolisporus T.H.Li, R.N.Hilton & Watling in Tylopilus with the North American taxon T. balloui (Peck) Singer. Thus, a new combination, Tylopilus phaseolisporus (T.H.Li, R.N.Hilton & Watling) Osmundson, Bougher, R.Rob. & Halling, is proposed for this brightly-coloured species that is apparently endemic to bushland in south-west Western Australia.
Tephrosia sabulosa (Fabaceae: Millettieae), a new species from Australia’s sandhill deserts
BUTCHER, R., Nuytsia 32: 109–119 (2021)
The new species described herein has been segregated from the complexes surrounding T. rosea Benth. and T. brachyodon Domin, both of which are extremely challenging taxonomically. Tephrosia sabulosa R.Butcher is distinctive; however, its relationship with the other members of these complexes is not yet known. It occurs in sandhill habitats on the crests and slopes of dunes and has a disjunct distribution in Australia, with all but one collection being made from the Simpson-Strzelecki Dunefields bioregion of the Northern Territory, South Australia and Queensland; nearly 900 km lies between these collections and that made from the Kiwirrkurra Indigenous Protected Area (Gibson Desert bioregion) in Western Australia. The new species is described and differentiated from similar taxa, and images and a distribution map are provided.
A revision of Lasiopetalum (Malvaceae: Byttnerioideae) from the northern sandplains of Western Australia, including two new species
SHEPHERD, K.A. AND WILKINS, C.F., Nuytsia 32: 121–149 (2021)
Taxonomic descriptions are provided for eight species of Lasiopetalum Sm. with a centre of diversity in the Geraldton Sandplains bioregion. Circumscriptions are updated for six species, namely L. angustifolium W.Fitzg., L. drummondii Benth., L. lineare Paust, L. ogilvieanum F.Muell., L. oldfieldii F.Muell., and L. oppositifolium F.Muell. Lectotypes are designated for L. angustifolium, L. ogilvieanum, L. oldfieldii, and L. oppositifolium, while the holotype for L. drummondii is clarified. In addition, two new species from the region are recognised and named here as L. biloculatum K.A.Sheph. & C.F.Wilkins and L. erectifolium K.A.Sheph. & C.F.Wilkins_._ Images and distribution maps are provided for all species.
Eucalyptus merleae (Myrtaceae), a new rare species endemic to Ravensthorpe Shire in south-west Australia
MCQUOID, N.K. AND FRENCH, M.E., Nuytsia 32: 151–158 (2021)
Eucalyptus merleae McQuoid & M.E.French, first collected by Ian Brooker in 1985, is described and illustrated. It is related to Eucalyptus astringens Maiden. The new species has a scattered distribution in the Ravensthorpe to Hopetoun area on the central south coast of Western Australia, is at risk from frequent fire, climate change and potential mining activity, and is in need of further survey and monitoring.
Austrobaeckea, a new south-western Australian genus of Myrtaceae (Chamelaucieae: Hysterobaeckeinae)
RYE, B.L., Nuytsia 32: 173–197 (2021)
The new Myrtaceous genus Austrobaeckea Rye is described, with eight species recognised. It is a member of tribe Chamelaucieae DC. subtribe Hysterobaeckeinae Rye & Peter G.Wilson and is restricted to the southern part of the South West Botanical Province of Western Australia. Three new species are named as A. columnaris Rye, A. fascifolia Rye and A. narembeen Rye, and the following new combinations are made: A. latens (C.R.P.Andrews) Rye, A. pygmaea (R.Br. ex Benth.) Rye, A. pachyphylla (Benth.) Rye, A. uncinella (Benth.) Rye and A. verrucosa (Turcz.) Rye. A lectotype is selected for A. uncinella. Three species have conservation priority.
New species of Western Australian Styphelia (Ericaceae: Epacridoideae: Styphelieae) from the S. pendula and S. conostephioides groups
HISLOP, M., Nuytsia 32: 199–238 (2021)
Eight new species and one new subspecies are described and illustrated. Six of these, S. caudata Hislop, S. globosa Hislop, S. graniticola Hislop, S. intermediana Hislop, S. intricata Hislop and S. madida Hislop belong to the S. pendula (R.Br.) Spreng. group (also known as Group V), and the other two, S. carolineae Hislop and S. exarata Hislop, are from the S. conostephioides (DC.) F.Muell. group (also known as Group VIII). Styphelia madida includes the subspecies hirtigera Hislop. A key is provided to species of the S. pendula group occurring in the south-west corner of Western Australia (i.e. west of a line between Perth and Albany), this being the main region of diversity for the group. Five of the new species have conservation coding.
Drummondita billyacatting (Rutaceae), a new, range-restricted species from Western Australia
SHELTON, L.R.J. AND THIELE, K.R., Nuytsia 33: 19–27 (2022)
The new species Drummondita billyacatting L.R.J.Shelton & K.R.Thiele is described for a taxon previously phrase-named as D. sp. Trayning (A.M. George 97), which is narrowly endemic to Billyacatting Hill in the Western Australian wheatbelt. The new species is morphologically readily separable from the widespread D. hassellii (F.Muell.) Paul G. Wilson and the morphologically rather similar D. longifolia (Paul G. Wilson) Paul G. Wilson. A key is provided to all species of Drummondita Harv. (Rutaceae).
Austrostipa (Poaceae) in Western Australia: new species, new records, keys, and character notes
WILLIAMS, A.R., Nuytsia 33: 39–101 (2022)
Austrostipa S.W.L.Jacobs & J.Everett is a monophyletic genus of temperate Australian native grasses that occur throughout the southern part of the continent and in New Zealand. Eight new species from Western Australia are described and illustrated here, plus two newly recorded species that are range extensions from their previously known habitats in South Australia, bringing the total number of species recorded in this state to forty-four. Detailed character notes and a key to the species and the accepted subgenera are provided. The new species are: A. anaiwaniorum A.R.Williams, A. burgessii A.R.Williams, A. everettiana A.R.Williams, A. frankliniae A.R.Williams, A. heteranthera A.R.Williams, A. koordana A.R.Williams, A. nunaginensis A.R.Williams and A. turbinata A.R.Williams. One former species (A. nullanulla J.Everett & S.W.L.Jacobs) has been reduced to synonymy with A. vickeryana J.Everett & S.W.L.Jacobs. The two species with range extensions are A. echinata (Vickery, S.W.L.Jacobs & J.Everett) S.W.L.Jacobs & J.Everett, which has been found at several sites around Esperance, and A. mundula (J.M.Black) S.W.L.Jacobs & J.Everett, which has been found in numerous small isolated coastal pockets around the south-west and up as far as Yanchep north of Perth. Five of the new species appear to be rare and isolated, including the newly discovered populations of A. echinata and A. mundula, and warrant conservation priority.
An expanded circumscription and revision of the Western Australian genus Balaustion (Myrtaceae: Chamelaucieae: Hysterobaeckeinae)
RYE, B.L., Nuytsia 33: 149–204 (2022)
Balaustion Hook. s. lat. comprises 18 species that are characterised by having a large cavity on the inner surface of their seeds. Other characters found in all or most of the species are a low growth form, sub-epidermal tissue on the young stems that disintegrates into fibres, one-flowered peduncles, scarcely keeled sepals, and very large, sessile placentas. The type species of Balaustion has a distinctive anther type and particularly large, colourful flowers adapted to bird-pollination, but white is the most common petal colour in the genus. New combinations are made for three species previously included in Baeckea L. s. lat.: Balaustion exsertum (S.Moore) Rye, B. grandibracteatum (E.Pritz.) Rye and B. grande (E.Pritz.) Rye. A neotype is selected for Baeckea grandibracteata E.Pritz. and lectotypes chosen for B. grandis E.Pritz. and the type species Balaustion pulcherrimum Hook. The new species and subspecies are B. baiocalyx Rye, B. bimucronatum Rye, B. filifolium Rye, B. grandibracteatum subsp. meridionale Rye, B. grandibracteatum subsp. juncturum Rye, B. hemisphaericum Rye, B. interruptum Rye, B. karroun Rye, B. mukinbudin Rye, B. multicaule Rye, B. polyandrum Rye, B. quinquelobum Rye, B. spenceri Rye, B. tangerinum Rye, B. thamnoides Rye and B. unguiculatum Rye. Most of these taxa are conservation-listed in Western Australia. Three sections are recognised: sect. Balaustion is monotypic, sect. Nonfibrosa Rye comprises three species with few ovules, and sect. Tilophloia Rye comprises 14 species characterised by stem tissue that tends to disintegrate into numerous fibres. One possible case of hybridisation between two of these sections is discussed.
Description of a new south-western Australian plant group, Hypocalymma sect. Grandiflora (Myrtaceae: Chamelaucieae: Astarteinae)
RYE, B.L., KEIGHERY, G.J. AND BARRETT, M.D., Nuytsia 33: 233–249 (2022)
A new section of Hypocalymma (Endl.) Endl., H. sect. Grandiflora Rye, Keighery & M.D.Barrett, is described. Like sect. Hypocalymma, the new section has seeds with a pitted testa, but it differs in having solitary axillary flowers with large petals greatly exceeding the length of the stamens. Its type species is H. puniceum C.A.Gardner and three of its five species are new: H. inopinatum Rye, Keighery & M.D.Barrett, H.magnificum Rye, Keighery & M.D.Barrett, and H. polyandrum Rye, Keighery & M.D.Barrett. Keys are given to the four sections of Hypocalymma and to the species of sect. Grandiflora. Four species have conservation priority.
Calytrix calingiri, a new species from the Calytrix acutifolia species group (Myrtaceae: Chamelaucieae)
NGE, F.J. AND THIELE, K.R., Nuytsia 33: 251–261 (2022)
A taxonomic assessment of Calytrix cravenii Nge & K.R.Thiele has shown that a distinct morphological variant that occurs near Calingiri in south-west Western Australia is best regarded as a distinct species. It is described here as Calytrix calingiri Nge & K.R.Thiele sp. nov.
A new species of Brachyachne (Poaceae: Chloridoideae: Cynodonteae) from semi-arid Northern Territory and Western Australia, and additional notes on the genus
ALBRECHT, D.E. AND MCLAY, T.G.B., Nuytsia 33: 263–274 (2022)
Brachyachne anisocarpa Albr. is described and illustrated, with notes on distribution, habitat and relationship with similar species. New distribution records of other Brachyachne (Benth.) Stapf species are provided, along with a key to Brachyachne species in Australia. The status of the genus is discussed based on an analysis of pre-existing and new molecular data.
A taxonomic review of the Styphelia tamminensis subgroup (Ericaceae: Epacridoideae: Styphelieae)
HISLOP, M. AND NGUYEN, H.K., Nuytsia 33: 275–320 (2022)
Within the heterogeneous Styphelia Sm. Group X, a distinctive Western Australian subgroup is recognised based on morphological and molecular data. A morphological synopsis of the subgroup is provided and the following 13 new species are described and illustrated: S. annulata Hislop, S. bracteolosa Hislop, S. echinulata Hislop, S. exilis Hislop, S. hyalina Hislop, S. incerta Hislop, S. pallens Hislop, S. papillosa Hislop, S. platyneura Hislop, S. recurva Hislop, S. roseola Hislop, S. scabrella Hislop and S. subglauca Hislop. Nine of the novel species are conservation-listed. A key to all 19 members of the subgroup is included.
Update to the taxonomy of Hypocalymma sect. Hypocalymma (Myrtaceae: Chamelaucieae), including hybrids and new species
KEIGHERY, G.J., RYE, B.L. AND TAUSS, C., Nuytsia 34: 21–60 (2023)
In updating the taxonomy of Hypocalymma (Endl.) Endl. sect. Hypocalymma (Myrtaceae: Chamelaucieae), the section is described, a key is provided to the species and hybrids, full descriptions given for 11 species (three of them new, one reinstated) and three hybrids (one newly named). Taxa needing further study are noted. Five species and two of the hybrids described here have conservation priority. Two new species are described from the H. xanthopetalum F.Muell. complex as H. lateriticola Keighery & Rye and H. quadrangulare Rye & Keighery. The circumscription of H. angustifolium (Endl.) Schauer is reduced with the reinstatement of H. suave Lindl. and the description of the new species H. balbakiae Tauss & Rye. A northern variant of H. balbakiae (previously known as H. angustifolium subsp. Hutt River) is considered to be insufficiently distinct to recognise formally as a subspecies. Evidence is presented that one previously named and two phrase-named taxa are hybrids. Two of the hybrids are known from more than one location and have been recorded in hybrid swarms: one between H. angustifolium and H. tetrapterum Turcz. is named as H. × proliferum Keighery & Rye, while the other, H. × linifolium Turcz., has the parent species H. angustifolium and H. lateriticola. The third hybrid is H. tenuatum × H. xanthopetalum. The description of H. jessicae Strid & Keighery is broadened to include a new variant that has mostly higher ovule and stamen numbers. Amendments are made to the stamen and ovule numbers recorded for H. sylvestre Strid & Keighery; this species has up to 200 stamens, which is the highest stamen number known for the tribe Chamelaucieae DC. A new fruit type that is indehiscent and somewhat winged, is recorded for the genus; it occurs only in H. serrulatum Strid & Keighery, which also has an unusual breeding system.
Four new species of Amanita sect. Roanokenses (Basidiomycota) from Western Australia
DAVISON, E.M., GIUSTINIANO, D., BARRETT, M.D. AND SYME, K., Nuytsia 34: 65–92 (2023)
Four species of Amanita Pers. are documented from Western Australia. Amanita brunneola E.M.Davison & Giustiniano is described from the Perth region. It is distinguished by its pale brown pileus, white universal veil, globose basal bulb, amyloid, cylindric spores and presence of clamp connections. Amanita cretaceaverruca E.M.Davison & Giustiniano is described from the Perth region and the southern jarrah forest. It is distinguished by its brown pileus, with a thick white warty universal veil, globose or ovoid basal bulb, amyloid, elongate spores and absence of clamp connections. Amanita mallee E.M.Davison, Giustiniano & M.D.Barrett is described from the Shire of Coolgardie. It is distinguished by its white pileus and universal veil, tapered basal bulb, amyloid, cylindric spores and abundant clamp connections. Amanita validiuscula E.M.Davison, Giustiniano & K.Syme is described from the wheatbelt and Yalgoo area. It is distinguished by its white pileus and universal veil, ivory lamellae, fusiform or tapered basal bulb, amyloid, ellipsoid spores and abundant clamp connections. Molecular analysis shows all these species are members of sect. Roanokenses. Amanita brunneola, A. cretaceaverruca and A. mallee form a clade with other species from Australia and New Zealand, which may indicate Gondwanan origin.
Amanita marinae (Basidiomycota), a new species from the mid-west region of Western Australia
DAVISON, E.M. AND GIUSTINIANO, D., Nuytsia 34: 111–123 (2023)
Amanita marinae E.M.Davison & Giustiniano from sect. Validae (Fr.) Quél. is described from Kwongan vegetation in the Lesueur Sandplain of the mid-west region of Western Australia. It is distinguished by a white to ivory pileus; white to pale vinaceous buff universal veil; a white, membranous, flaring partial veil; amyloid elongate spores; and absence of clamp connections. Its affinities with other members of sect. Validae are unclear as phylogenetic analyses of nuLSU and tef-1 sequences show affinities with northern hemisphere species, whilst comparison of ITS sequences shows affinities with an undescribed species from New Zealand. Variability in the ITS region between cloned haplotypes of A. marinae was less than 1% — comparable with haplotype divergence previously observed for other sect. Validae.
Taxonomic resolution of infraspecific taxa in Lambertia orbifolia (Proteaceae) using molecular and morphological evidence
WEGE, J.A., MONKS, L.T., WEBB, A.D., BINKS, R.M. AND COATES, D.J., Nuytsia 34: 125–137 (2023)
The taxonomy of three informally-named, conservation-listed subspecies of Lambertia orbifolia C.A.Gardner was assessed using genotypic data generated from microsatellites in concert with morphological information. They were found to warrant formal taxonomic recognition and individualised conservation management. Lambertia orbifolia subsp. vespera A.D.Webb, L.Monks & Wege, an Endangered taxon from the Scott River Plains, and L. orbifolia subsp. pecuniosa A.D.Webb, L.Monks & Wege, a recently discovered and apparently rare taxon from south-west of Bowelling, are newly described and comparative data are provided for L. orbifolia subsp. orbifolia, a Critically Endangered taxon found near Narrikup. A revised description of L. orbifolia is also provided.
The taxonomy of the Styphelia corynocarpa subgroup (Ericaceae: Epacridoideae: Styphelieae)
HISLOP, M., Nuytsia 34: 139–155 (2023)
A small subgroup within the heterogeneous Styphelia Sm. Group X is recognised based on morphological and molecular data. A morphological synopsis of, and key to, the subgroup are provided, and all four member species are described and illustrated. Three of the four species are described as new, S. anomala Hislop, S. cylindrica Hislop and S. planiconvexa Hislop, while S. corynocarpa (Sond.) F.Muell. is given an updated description. Styphelia anomala has Western Australian conservation listing as Priority Two.
Ferdinand Mueller in Western Australia in 1877, with notes on his later contributions to the Western Australian flora
DOWE, J.L., Nuytsia 34: 157–178 (2023)
Baron Ferdinand von Mueller, Australia’s most productive botanist of the mid–late nineteenth century, was especially enamoured with the flora of Western Australia, and wrote about its ‘marvellous exuberance’, ‘typic singularity’ and ‘endemism’. He botanised in Western Australia on three occasions: in 1856 in the Sturt Creek area during Augustus Gregory’s North Australian Exploring Expedition; in 1867 in the Porongurup Range and Stirling Range and around Albany; and in 1877 with excursions from Champion Bay to Shark Bay and from Perth to Albany. Although he considered that most of Australia’s plant taxa had been described by the late 1870s, he remained attentive for novelties, especially those that were rare or from remote, under-botanised areas, especially in Western Australia. Many of Mueller’s later publications consolidated aspects of nomenclature, systematics, biogeography, economics, horticulture and utilisation of the flora of Western Australia.
Echinostelium australiense (Myxomycetes: Echinosteliaceae), a new species of slime mould described from Western Australia
KNIGHT, K.J., STEPHENSON, S.L. AND NOVOZHILOV, Y.K., Nuytsia 34: 179–186 (2023)
A new and unusual species of Echinostelium de Bary appearing on samples of bark collected in Western Australia and placed in moist chamber cultures is described and illustrated. This new species is clearly distinct from all other species of Echinostelium as it differs in a number of morphological and colour characters. The dark colouration of the sporotheca, stalk and spores with distinct patches of closely arranged warts arranged in a loosely circular pattern, and a large bi-coloured petaloid collar are unusual for the genus.
Volvopluteus earlei and Volvariella taylorii: new fungi for Western Australia (Basidiomycota, Agaricales, Pluteaceae)
BOUGHER, N.L. AND BARRETT, M.D., Nuytsia 34: 187–201 (2023)
Re-examination of vouchered specimens of pink-spored, volvate, agaricoid fungi held at the Western Australian Herbarium (PERTH) has revealed the first recorded occurrences in Western Australia of Volvopluteus earlei (Murrill) Vizzini, Contu & Justo and Volvariella taylorii (Berk. & Broome) Singer, and affirmed the regional prevalence of Volvopluteus gloiocephalus (DC.) Vizzini, Contu & Justo. The identities of the two Volvopluteus Vizzini, Contu & Justo taxa were confirmed with molecular data relative to extra-Australian samples validated in previous studies. Volvopluteus earlei had not been previously reported from Australia. Evidently Volvopluteus earlei and Volvariella taylorii are less common in Australia than the larger and more often encountered Common Rosegill, Volvopluteus gloiocephalus.
Marasmius australotrichotus (Marasmiaceae), a new setose species from Australia, and an intriguing range extension for M. paratrichotus
GUARD, F.E., DEARNALEY, J., LEBEL, T., BARRETT, M.D. AND BOUGHER, N.L., Nuytsia 34: 203–219 (2023)
Based on morphological characters and molecular analysis of the nrITS regions, Marasmius australotrichotus F.E.Guard, J.Dearnaley & T.Lebel, the first known Australian species in sect. Sicci, ser. Spinulosi is described. The distribution of M. paratrichotus is extended from the West African island nation of São Tomé and Príncipe (ST&P) to Christmas Island (CI) and northern Western Australia (WA). Classification, distinguishing characters, habitat variability, geographic distribution and possible dispersal mechanisms are discussed.
Revision of the connate bract group allied to Goodenia panduriformis (Goodeniaceae), including recognition of three new species
SHEPHERD, K.A. AND LEPSCHI, B.J., Nuytsia 34: 227–254 (2023)
The taxonomy of several species of Goodenia with connate bracts allied to G. panduriformis (A.Cunn. ex Benth.) K.A.Sheph. was evaluated through morphological assessment of herbarium specimens. Consequently, the circumscriptions of G. connata (F.Muell.) K.A.Sheph., G. discophora (F.Muell.) K.A.Sheph., G. daviesii (F.Muell.) K.A.Sheph. and G. panduriformis are revised and new descriptions provided. Three new species, G. aluta K.A.Sheph. & Lepschi, G. crescentiloba K.A.Sheph. & Lepschi and G. obscurata K.A.Sheph. & Lepschi are also recognised, the latter being listed as a species of conservation concern. Further, a replacement lectotype for Velleia helmsii K.Krause is designated and a key, distribution maps and figures are included.
Four new species of Triodia (Poaceae) from the Pilbara and adjacent bioregions, Western Australia
BARRETT, M.D., DE KOCK, P.-L. AND DILLON, S.J., Nuytsia 34: 261–294 (2023)
The Australian hummock genus Triodia R.Br. is currently undergoing taxonomic revision in light of new collections from surveys of remote Australia and increased resolution provided by molecular methods. This paper describes four new species of Triodia from the Pilbara and adjacent IBRA bioregions: T. avenoides M.D.Barrett, T. degreyensis M.D.Barrett, T. karijini M.D.Barrett & S.J.Dillon, and T. lutiteana M.D.Barrett & P.-L.de Kock. All four species are ‘soft’ spinifexes with elongate glumes and lemma lobes subulate to awned, and are only known from the Pilbara and adjacent Carnarvon and Gascoyne regions of Western Australia. Triodia degreyensis is known from a single range system in the north-eastern Pilbara. The taxon formerly known by the phrase name T. sp. Karijini (S. van Leeuwen 4111) is formally described here as T. karijini, and is restricted to mountains above 900 m altitude in the eastern Hamersley Range. Triodia lutiteana is only known from shale substrates north-west of Tom Price, and may be a polyploid species. The new species T. avenoides is segregated from T. schinzii (Henrard) Lazarides based on morphological and molecular differences and a disjunct distribution on sand sheets and dunes of the Carnarvon basin. The central Australian species T. helmsii (C.E.Hubb.) Lazarides is newly synonymised with T. schinzii, since no clear morphological or genetic differences between the two could be established. An amended description of T. schinzii is provided to accommodate these alterations to the species concept. Diagnostic character combinations for each species are given to allow discrimination from all other Triodia species. Triodia degreyensis, T. karijini and T. lutiteana are known from between one and four localities, and have priority conservation statuses, while T. avenoides and T. schinzii are not considered threatened. With the species described here, a total of 29 species and one hybrid are now known from the Pilbara bioregion and its immediate surrounds.
New combinations of Hibbertia (Dilleniaceae) segregated from H. hibbertioides and H. glomerata
HAMMER, T.A. AND THIELE, K.R., Nuytsia 35: 31–45 (2024)
Infraspecific taxa within the southwest Australian species Hibbertia glomerata Benth. and H. hibbertioides (Steud.) J.R.Wheeler are critically re-evaluated. Morphological evidence is presented to recognise H. glomerata subsp. wandoo J.R.Wheeler and H. hibbertioides var. meridionalis J.R.Wheeler at species rank, as H. wandoo (J.R.Wheeler) T.Hammer & K.R.Thiele and H. meridionalis (J.R.Wheeler) T.Hammer & K.R.Thiele respectively. Hibbertia hibbertioides var. pedunculata J.R.Wheeler is reduced to synonymy under H. hibbertioides. The remaining subspecies in H. glomerata are provisionally retained but are marginally distinct.
