Abstract Phylogenetic relationships of the two Malagasy Sapotaceae endemic genera Capurodendron and Tsebona have been
unclear until now. Recent collections from Madagascar, as well as a better representation of the tribe Isonandreae, altogether 95
terminals, were used to estimate a phylogeny of subfamily Sapotoideae. We analysed sequences of nrDNA (ITS) and cpDNA
(trnH-psbA) with Bayesian inference and parsimony jackknifing. As in previous analyses, Sapoteae and Sideroxyleae are
recovered monophyletic. In addition, Isonandreae, distributed in the Indo-Pacific, is for the first time resolved as monophyletic and sister to Sapoteae. All Malagasy accessions of Capurodendron, Tsebona, and a new species are grouped in another
well-supported clade. This clade is accommodated in a new tribe Tseboneae characterized by caducous stipules, 5-merous
flowers with quincuncial sepals, contorted aestivation of corolla lobes, absence of corolla appendages, one or three stamens
opposite each corolla lobe, villous staminodes, seeds with an adaxial scar and plano-convex cotyledons, lacking endosperm.
The new species is described in the new genus Bemangidia (B. lowryi) because it has a unique leaf venation for the tribe and
combines different morphological features from Capurodendron and Tsebona. All three genera are well-supported monophyletic groups. Bemangidia lowryi is threatened with extinction due to extensive ongoing forest destruction and is assigned a
preliminary conservation status of Critically Endangered.

INTRODUCTION
Madagascar is well-known for its high diversity of living
organisms and especially for its unrivalled high level of endemism. Vascular plants are no exception to this pattern with a
recently estimated richness of 10,889 native species in 1617
genera, with 82% endemism at the species level and 20% at
the genus level (Callmander & al., 2011). Being only 400 km
away from mainland Africa, it seems obvious that the closest
relatives of Malagasy vascular plants are to be found in that
continent. Accordingly, it is not surprising that Engler (1882) included Madagascar in his “African territory”. A recent estimate
of similarity between Madagascar and Sub-Saharan African
vascular floras (Gautier & al., 2012) revealed a very low value
at the species level (0.029) but an eight-fold higher value at the
genus level (0.246). However, as already pointed out by Engler
(1882), Indo-Pacific elements also contribute to the flora of
Madagascar, which have been reviewed by Schatz (1996).
Like many other woody tropical families, Sapotaceae reach
an unusually high score of species endemism in Madagascar.
Although many taxa remain to be described, 81 of the 84 currently accepted species are endemic (96%; Gautier, 2003),
which is close to the 98% endemism of the family in New
Caledonia (Swenson, 2011). Depending on generic concepts,
generic endemism is between 27% and 33%. Three genera are
972
endemic to Madagascar: Capurodendron Aubrév., Faucherea
Lecomte, and Tsebona Capuron. The non-endemic genera are
either pantropical (Manilkara Adans., Sideroxylon L.), palaeotropical (Donella Pierre ex Baill., Gambeya Pierre, Mimusops L.), or are shared with neighbouring western Indian Ocean
islands (Labourdonnaisia Bojer, Labramia A. DC.). In the present state of our knowledge, there is no Sapotaceae genus shared
between Madagascar and the Indo-Pacific area that does not
occur elsewhere.
Classification of Sapotaceae has long been a matter of dispute as exemplified by the fact that one year after Aubréville’s
(1964) generic monograph of the family, which considered 122
genera in 15 tribes and four subfamilies, Baehni (1965) retained
only 63 genera in six tribes and three subfamilies. The latest
generic treatment by Pennington (1991) did not use subfamilies
but recognized the five tribes Chrysophylleae, Isonandreae,
Mimusopeae, Omphalocarpeae, and Sideroxyleae, with a total
of only 53 genera, which can be interpreted as an extreme attempt to reconcile points of views through lumping. Analyses
of molecular data dramatically improved our understanding
of Sapotaceae phylogeny and have repeatedly demonstrated
that many of Pennington’s (1991) larger genera are not monophyletic and tend to draw us back to Aubréville’s (1964) finer
generic divisions. For example, Planchonella Pierre, Pleioluma
(Baill.) Baehni, Sersalisia R. Br., and Van-royena Aubrév. are all

Gautier & al. • New species, genus and tribe of Sapotaceae
Pouteria Aubl. segregates that have been reinstated for groups
in Australasia (Swenson & al., 2007, 2013). In Africa, Aningeria
Aubrév. & Pellegr., Donella, Gambeya, and Malacantha Pierre
are Chrysophylloideae satellite genera that need to be resurrected, but their circumscriptions are still unclear (Swenson
& al., 2008b).
Analyses of molecular data have also dramatically improved our understanding of Sapotaceae phylogeny at levels
higher than the genus. Following the works of Anderberg
& Swenson (2003), Swenson & Anderberg (2005), and Smedmark & al. (2006), it is now established that apart from the
basal genera Sarcosperma Hook. f. and Eberhardtia Lecomte,
all other extant Sapotaceae originated from two main evolutionary lineages to which the rank of subfamily is applied,
viz. Chrysophylloideae and Sapotoideae. Unfortunately, these
two clades do not conform to the classical (e.g., Aubréville,
1964) dichotomy based on calyx structure. Although Chrysophylloideae all have a single whorl of sepals, this character
state is also present in part of Sapotoideae, the other members of the latter subfamily having two whorls of three or four
calyx lobes. Recent phylogenies of Sapotoideae (Anderberg
& Swenson, 2003; Swenson & Anderberg, 2005; Smedmark
& al., 2006) have already revealed two monophyletic groups
that are formally accepted at tribal rank: Sapoteae (including the Malagasy endemic Faucherea and its near-endemic
relatives Labourdonnaisia and Labramia) and Sideroxyleae
(with a few amendments compared with Pennington, 1991)
whereas relationships among the other genera in the subfamily,
including those formerly included in Isonandreae, remained
uncertain. Specifically, regarding the remaining two endemic
Malagasy genera, the position of Capurodendron was unclear,
and the relationships of Tsebona have never been investigated.
Capurodendron comprises 23 species of trees and shrubs
in dry and wet lowland forest types (Aubréville, 1974), and is
the third-largest endemic genus in Madagascar (Callmander
& al., 2011). This genus is characterized by caducous stipules,
5-merous flowers with quincuncial sepals and contorted corolla lobes, connivent woolly staminodes that form a chamber above the ovary, and a seed scar that is adaxial or tends
to be basi-ventral. It was placed by Aubréville (1964) in the
Pouterieae, in the Chrysophylleae by Pennington (1991), but
transferred to Sapotoideae with uncertain affinity by Swenson & Anderberg (2005). These latter authors hypothesized
that it could be related to the Asian genera Burckella Pierre
and Diploknema Pierre in tribe Isonandreae sensu Pennington
(1991). Unfortunately, only one species of Capurodendron and
a restricted number of representatives of tribe Isonandreae were
included in previous phylogenetic studies, which prevented a
better resolution of the whole group.
Tsebona, with the so far only known species T. macrantha
Capuron, occurs as a tall tree in the lowland evergreen forests
of north-eastern Madagascar. It is characterized by the presence of stipules, a calyx of five sepals that are partly induplicate
valvate, five contorted corolla lobes, 15 stamens organized in
five bundles of three opposite each corolla lobe, and a seed scar
covering 75% of the seed surface. Presence of multiple stamens
per corolla lobe has led generic monographers of the family to
include Tsebona in tribe Omphalocarpeae (Aubréville, 1964;
Pennington, 1991). However, Pennington concluded that the
flower morphology of Tsebona has nothing in common with
other members of Omphalocarpeae and suggested that it is an
isolated genus, possibly better placed in Mimusopeae or Isonandreae on account of floral and pollen structure. Swenson
& Anderberg (2005) demonstrated the polyphyly of Omphalocarpeae and united it with Chrysophylleae (Chrysophylloideae). However, Tsebona was not included in their study and
the placement of the genus remains unknown.
During an expedition to SE Madagascar in 2006, a flowering specimen of Sapotaceae was collected in Bemangidy Forest, 55 km NNE of Fort Dauphin (Tolagnaro) (Fig. 1A–B). The
plant matched an earlier sterile but unidentified collection from
the same locality hosted in the Paris herbarium. Field images
revealed a general appearance of Tsebona including thick terminal twigs, large leaves on long petioles, a 5-merous flower,
and a particular type of quincuncial calyx structure similar to
the one described by Capuron for Tsebona (1962, his figure 1).
Dissection of the flower revealed further characters in common
with Tsebona such as hairy staminodes and a gynoecium of five
fused uniovulate carpels. However, a brochidodromous leaf
venation with close, weak parallel secondaries (Fig. 1D; not
eucamptodromous with prominent secondaries) and one stamen
opposite each corolla lobe (not three—see Fig. 1E), are characters that distinguish it from T. macrantha. Furthermore, in the
endeavour of gathering fresh material for molecular analyses,
we recently collected a fruiting specimen in the type locality,
(Fig. 1C, F) which displayed a seed scar (Fig. 1G) that covers
less than 30% of the seed surface (not 75%). Flower structure
of this species also shares several features with Capurodendron
including connivent hairy staminodes that form a chamber
above the ovary, but the calyx aestivation is different. Without
doubt, this material represents a new endemic species of Sapotaceae for Madagascar, but its relationship to Capurodendron,
Tsebona, or other genera is unclear.
In this paper we explore phylogenetic relationships within
subfamily Sapotoideae by using Bayesian inference and parsimony analyses based on nrDNA and cpDNA sequence data.
There are four specific points we wish to address: (1) to explore
the monophyly of Capurodendron, (2) to place Tsebona in a
phylogenetic framework, (3) to test whether the novel species
from Bemangidy Forest is closely related to Tsebona, and (4)
to test the monophyly of tribe Isonandreae.
MATERIALS AND METHODS
Nomenclature. — The subfamily and partly the tribal
classification follow that of Swenson & Anderberg (2005). In
order to test the monophyly of Isonandreae, we refer to the classification by Pennington (1991). The checklist of Sapotaceae
(Govaerts & al., 2001) includes published names and synonyms
to species and genera.
Taxon sampling. — A total of 95 terminals were selected
for this study (Appendix 1), which include representatives of all
genera of Isonandreae sensu Pennington (1991), a significant

geographic sample of Sideroxyleae (Smedmark & Anderberg,
2007), as well as Sapoteae (Swenson & Anderberg, 2005). The
general collecting programs of the Conservatoire et Jardin
Botaniques de la Ville de Genève (CJB) in northern and western
Madagascar enabled us to considerably improve the sampling of
Capurodendron. Two dedicated expeditions conducted by CJB
and the Swedish Museum of Natural History in 2010 and 2011
added silica gel-dried material of several species in the genus
and allowed us to collect Tsebona macrantha as well as further
specimens of the new species. Fresh specimens were dried in
silica gel and complemented the few herbarium specimens from
which we were able to extract DNA. In total, nineteen accessions
of Capurodendron, two of Tsebona macrantha, and six of the
new species were included in the study. Sequencable material
of the type species of Capurodendron (C. rubrocostatum (Jum.
& H. Perrier) Aubrév.) is unfortunately not yet available. Based
upon inferences from our earlier studies, we rooted our tree
with Neohemsleya T.D. Penn., a member of Chrysophylloideae
(Smedmark & al., 2006; Swenson & al., 2008b).
Molecular data. — Total genomic DNA was isolated using either the CTAB method of Doyle & Doyle (1987) or the
NucleoSpin Plant II kit (Machery-Nagel, Düren, Germany).
All precautions were taken to avoid contaminations, specifically for the herbarium specimens: the leaves were ground in

a Qiagen Tissue Lyser using tungsten beads previously washed
in a 0.4 M HCl solution, the beads, the bench, the pipets and the
tubes were UV irradiated before use, and filter tips were systematically utilized for all steps before amplification. The specimens were genotyped for the chloroplast trnH-psbA spacer and
for the nuclear ribosomal internal transcribed spacer ITS. For
each locus, regular PCRs were used on silica gel–dried specimens and nested PCRs were used on herbarium specimens. The
trnH-psbA spacer was amplified using the primers designed by
Hamilton (1999) and by Naciri & Manen (2010) for regular and
nested PCRs (Table 1). Double-stranded DNA was amplified by
polymerase chain reaction (PCR) in a total volume of 20 µl. The
PCR mix contained 2 µl of the 10× PCR Fast Start Taq DNA
Polymerase buffer containing 20 mM MgCl2 (Roche, Rotkreuz,
Switzerland), 0.2 µl of 5% bovine serum albumin acetylated
solution (BSA), 0.4 µl 10 mM of each dNTPs (Roche), 1 µl of
each primer (10 µM), 0.15 µl 5 U/µl of Fast Start Taq DNA
Polymerase (Roche) and 1 µl of genomic DNA. PCR reactions
included an initial denaturation step of 5 min at 95°C, followed
by 35 cycles with 45 s denaturation at 96°C, 1 min annealing
at 52°C for trnH-psbA or at 59°C for ITS, 1 min extension at
72°C, and a final extension of 7 min at 72°C. In some cases,
and exclusively for herbarium specimens, the number of cycles
was increased to 40. When nested PCRs were necessary, the
amplifications were obtained using touch down programs with
an initial denaturation step of 4 min at 95°C followed by 1 min
denaturation, 30 s annealing and 1 min extension. For ITS,
the annealing temperature was initially fixed at 64°C and decreased by 1°C at each cycle to 55°C for the first 10 cycles and
was then stabilized at 55 °C for the remaining 25 cycles. For
trnH-psbA, the annealing temperature was initially fixed at
64°C and decreased by 1°C at each cycle to 61°C for the first
5 cycles, was then stabilized at 60 °C for 10 cycles, decreased
again for 5 cycles to 56°C and was finally stabilized at 56°C
for the 12 last cycles.
DNA sequencing was performed using the BigDye Terminator v.3.1 (Applied Biosystems, Delaware, U.S.A.). Both
strands were sequenced separately in a 10 µl reaction mix with
1 µl of the purified PCR product, 2 µl of the amplification primers at 1 mM, 4 µl of purified water, 1 µl of the 5× reaction buffer
and 2 µl of BigDye Terminator. Sequence reactions included
24 cycles of 10 s denaturation at 96°C, 5 s annealing at 50°C,
4 min extension at 60°C. The sequence reactions were run on an
ABI PRISM 377 DNA automated sequencer (PE Biosystems,
Waltham, Massachusetts, U.S.A.). The forward and reverse
sequences were assembled using Sequencher v.4.8 software
(Gene Codes Corporation, Ann Harbor, Michigan, U.S.A.) and
were aligned using the BioEdit Sequence Editor v.7.0.9.0 (Hall,
1999).
Bayesian analysis. — Evolutionary models for the molecular data were selected based on the Akaike information criterion (AIC; Akaike, 1973), which was calculated with MrAIC
(Nylander, 2004). For the trnH-psbA dataset, the general time
reversible substitution model (GTR; Tavaré, 1986) with gamma
distributed rate variation among sites (+ Γ) was selected. For
ITS, the GTR + Γ model, with a portion of sites being invariable,
was selected. Coded indels were included as a separate partition, which was analysed as standard data using the Markov k
model (Lewis, 2001) + Γ.
Bayesian inference analysis (Rannala & Yang, 1996; Yang
& Rannala, 1997) of the combined dataset, under a mixed model
incorporating the submodels selected for each individual dataset, was performed in MrBayes v.3.2 (Huelsenbeck & Ronquist,
2001; Ronquist & Huelsenbeck, 2003). The Markov chain was
run for 50 million generations, sampling every 5000 generations, and was assumed to have reached convergence when plots
of the overall likelihood, as well as individual parameters of the
model, were fluctuating around stable values. At this point, the
average standard deviation of split frequencies for two analyses
run in parallel was less than 0.01 and the potential scale reduction factor was 1.00 for all parameters. Phylogenetic hypotheses
sampled during the first 1,000,000 generations were discarded
as “burn-in” and the remaining trees from the two parallel analyses were used to construct a majority-rule consensus tree and
to calculate posterior probabilities of clades. The analysis was
repeated three times to make sure that independent runs converged on similar topologies containing the same nodes with
posterior probabilities (PPs) greater or equal to 0.95. Posterior
probabilities below 0.8 are not reported.
Parsimony analysis. — Jackknife analysis (Farris & al.,
1996), as implemented in PAUP* v.4.0 (Swofford, 2002), was
performed on the dataset to retrieve parsimony support values. The settings were: 1000 jackknife replicates with a single
random addition sequence, TBR branch swapping, collapsing
branches of zero length, steepest descent not in effect, and saving a maximum of 1000 trees in each replicate. The excluded
fraction of characters in each replicate was set to 37%. Parsimony jackknife values (JK) below 50% are not reported; group
frequencies of 50%–74% are considered weak, 75%–89% as
moderate, and ≥ 90 as strongly supported.

Gautier & al. • New species, genus and tribe of Sapotaceae
RESULTS
Bayesian analysis and parsimony jackknifing of the molecular dataset partitions (ITS, trnH-psbA, indels) recovered
similar tree topologies of Sapotoideae, although the former is
better resolved (Fig. 2). Some nodes receive posterior probabilities between 0.8 and 0.98, and these may lack jackknife
support. The tribes Isonandreae, Sapoteae and Sideroxyleae,
as well as another clade here referred to as the “New Tribe”
are recovered with strong Bayesian support while jackknife
recovers these clades with moderate to strong support. The
relationships between the tribes are uncertain, which is mainly
due to some taxa being embedded between the tribes, viz. the
sister pair Lecomtedoxa (Pierre ex Engl.) Dubard and Neolemonniera Heine are recovered between Sideroxyleae and
the rest of Sapotoideae, and Inhambanella (Engl.) Dubard is
placed between Isonandreae and Sapoteae. Northia Hook. f., a
monotypic genus confined to the Seychelles, has an isolated
position with moderate Bayesian support (PP 0.91), outside of
the New Tribe, sister to Isonandreae and Sapoteae.
Capurodendron is recovered with maximum support and
two subclades within the genus can be distinguished. Molecularly, the genus is easily distinguishable from all other taxa,
especially in the trnH-psbA intron, because at position 154, a
deletion of 17 base pairs is present in all members. All accessions referred to C. bakeri (Scott-Elliot) Aubrév. form a clade,
and two specimens of uncertain determination (LG 5780, LG
5788) fall out together but without significant support. The two
accessions of Tsebona macrantha from north-eastern Madagascar form a well-supported monophyletic group, and all six
accessions from Bemangidy Forest in southeast Madagascar
form another. Although the relationships of Capurodendron,
Tsebona, and the new species from Bemangidy Forest are still
unclear, they constitute three well-supported monophyletic
groups.
DISCUSSION
The present phylogeny of Sapotoideae must be considered well-resolved and well-supported although only based on
the nuclear marker ITS and the chloroplast marker trnH-psbA
(Fig. 2). A previous phylogenetic study of the subfamily used
five cpDNA markers with moderate success (Smedmark & al.,
2006). Our study is congruent with recent phylogenies of the
subfamily (Anderberg & Swenson, 2003; Swenson & Anderberg, 2005; Smedmark & al., 2006) by confirming that Sapoteae
and Sideroxyleae are monophyletic, that relationships among
tribes are not satisfactorily resolved, and that the position of
the genera assigned to Glueminae sensu Pennington (1991),
together with Northia, partly floats around in the phylogeny.
Smedmark & Anderberg (2007) demonstrated that Sideroxylon
oxyacanthum Baill. is not part of Sideroxylon and is better
placed in Spiniluma (Baill.) Aubrév. (Aubréville, 1963), a genus occupying a basally branching position within subfamily
Chrysophylloideae, and which is probably closely related to the
Asian genus Xantolis Raf. We confirm this conclusion.
976
New in the present analysis is the discovery of a strictly
endemic Malagasy clade that comprises three lineages, viz.
Capurodendron, Tsebona, and the new species from Bemangidy Forest. This clade has been impossible to detect before
because of insufficient sampling. Swenson & Anderberg (2005)
used one species of Capurodendron and placed the genus in
Sapotoideae, but with uncertain affinity. Smedmark & al.
(2006) used two samples of Capurodendron that grouped with
strong support but without strong indication of relationships.
Isonandreae with seven genera as circumscribed by
Pennington (1991) is for the first time recovered as monophyletic and receives strong posterior probability (PP 0.98; Fig. 2).
The tribe is distinguished by a calyx that usually has two whorls
of two or three sepals, undivided corolla lobes, and the absence
of staminodes (Table 2). In contrast, its sister group Sapoteae
usually has divided corolla lobes and staminodes present although exceptions exist. However, with the limited sample of
19 accessions in a group in which more than 250 species are
currently recognized, it is obvious that future phylogenetic
research is necessary to clarify natural limits of genera within
Isonandreae. For instance, three accessions of Palaquium
Blanco are found in a grade to the sister pair Aulandra longifolia H.J. Lam and Diploknema oligomera H.J. Lam, the latter
genus being polyphyletic with the other species associated with
Payena. Moreover, species of Madhuca Ham. ex J.F. Gmel. are
found in two different well-supported subclades that are distantly related within the tribe. Also, the entire tribe is restricted
to Asia with members of Burckella and Palaquium extending
into the Pacific as far as Fiji (Smith, 1981). Needless to say, the
rapid deforestation of Asia imposes tremendous exploitation
pressure on the group and intense phylogenetic research as well
as conservation assessments are urgently needed.
Northia Hook. f., a monotypic genus confined to the Seychelles, has a calyx of two whorls with three sepals each, more
or less entire corolla lobes, and vestigial staminodes (Table 2).
Aubréville (1964) associated it with genera such as Manilkara and Mimusops that now are accommodated in Sapoteae
(Swenson & Anderberg, 2005). Pennington (1991) placed Northia in his subtribe Manilkarinae, but stressed that it was the
only member of the group lacking endosperm in its seeds. Our
present analyses recover Northia as sister to the pair Isonandreae-Sapoteae with moderate posterior probability (PP 0.91) but
without jackknife support. This position should be considered
preliminary.
Pennington (1991) classified Inhambanella and the two
closely associated genera Lecomtedoxa and Neolemonniera
in Glueminae, a subtribe of Mimusopeae with one member
(Eberhardtia) now placed in Sarcospermatoideae (Smedmark
& al., 2006). The nominal genus Gluema Aubrév. & Pellegr.
is still unavailable for molecular analysis, but it is unlikely a
member of the identified Malagasy clade since it lacks stipules,
has divided corolla lobes, and staminodes are inserted inside
and opposite the stamens. Gluema is furthermore restricted to
West Africa. Inhambanella is presently recovered in between
Isonandreae and Sapoteae, but this position is supported by
very weak jackknife (JK 52; Fig. 2). Interestingly, the calyx
of Inhambanella generally consists of a single whorl of five

sepals (as in Isonandreae), but some flowers display a biseriate
calyx of 2 + 2 or 3 + 3 sepals (as in Sapoteae; Table 2). Gluema
shares with both Lecomtedoxa and Neolemonniera the unique
feature of having a dehiscing fruit. The two latter genera form
a well-supported group (PP 0.99; JK 0.78) although its sister
relationship is still uncertain, but it is not nested within the
Malagasy clade, Isonandreae, or Sapoteae. Formal recognition
of this clade should wait until Gluema becomes available for
molecular analysis.
Tseboneae and Bemangidia. — The pertinent question is
if the Malagasy clade can be recognized as a new tribe. A close
relationship between Capurodendron and Tsebona has long
been obscured by the 15 stamens organized in five bundles of
three opposite each corolla lobe in the latter, resulting in its artificial placement in Omphalocarpeae. The number of stamens
opposite each corolla lobe in the family can be very homoplastic and differs between sister species as demonstrated for the
New Caledonian genus Pycnandra (Swenson & al., 2008a).
However, Capurodendron and Tsebona share many important
features like the presence of generally caducous stipules, a
5-merous quincuncial calyx, contorted corolla lobes without
appendages, villous staminodes, an adaxial seed scar and an
embryo with plano-convex cotyledons lacking endosperm. The
new species conforms perfectly to these morphological traits
(Table 3). The molecular analysis conducted here provides
further support to group all these three lineages in a separate monophyletic group, endemic to Madagascar. Despite the
uncertain relationships of Northia and Inhambanella, as well
as the sister relationship of Lecomtedoxa and Neolemonniera,
the identified group is sister to Isonandreae and Sapoteae, two
monophyletic tribes distinguished on character combinations
(Table 2). We therefore suggest, in conjunction with the other
two tribes, that the identified clade should likewise be recognized as a tribe, viz. Tseboneae.
Considering the earlier history of splitting and lumping
genera in Sapotaceae, it can be discussed if the identified group
should be recognized as one, two, or three genera, all being
acceptable solutions without violating the primary principle of
monophyly (Backlund & Bremer, 1998). One possibility is to
accommodate all lineages in a single genus with three clearly
distinct subgenera. However, comparing the morphology of
Capurodendron, Tsebona, and the new species, it is clear that a
quite heterogeneous assemblage would be formed with species
that differ regarding leaf venation, sepal aestivation, number
of stamens opposite each corolla lobe, and percentage of seed
surface occupied by the scar (Table 3). Moreover, at the molecular level, the deletion of 17 base pairs in the trnH-psbA chloroplast intron clearly distinguishes all Capurodendron species
from other accessions in this clade, which supports the notion
to maintain it as a separate genus. A second option could be to
consider the new species as part of Tsebona, but this is a suboptimal solution since there is no support for such a relationship.
Regarding morphology, these taxa are distinguished by leaf
venation type, number of stamens, relative size of staminodes,

TAXON 62 (5) • October 2013: 972–983
Gautier & al. • New species, genus and tribe of Sapotaceae
Bemangidia L. Gaut., gen. nov. – Type: B. lowryi L. Gaut.
Leaf venation brochidodromous with many, closely
packed, parallel and weak secondaries, difficult to distinguish
from the parallel tertiaries; calyx lobes 5, quincuncial, outer
two with strongly involute margins that cause impressed longitudinal grooves on the external surface of the three inner
sepals; corolla lobes 5, contorted, overlapping to the right;
stamens 5; staminodes 5, villous, connivent and forming a
chamber above the ovary; fruit 1-seeded with seed scar covering 30% of seed surface; embryo with plano-convex cotyledons; endosperm absent.
Bemangidia differs from Tsebona by brochidodromous
leaf venation (instead of eucamptodromous), five stamens (instead of 3 × 5), the staminodes that are connivent and form
a chamber above the ovary, a single-seeded fruit (instead of
1–5 seeds), and a seed scar that occupies 30% of the seed surface (instead of 75%). Bemangidia differs from Capurodendron
similarly by leaf venation, but also in sepal aestivation which
causes an impressed median groove on the inner sepals, similar
to the pattern in Tsebona but absent in Capurodendron, and by
larger flowers, ca. 30 mm long compared to a 2–12 mm long
corolla in Capurodendron.
The genus is named after Bemangidy forest that is located approximately 55 km NNE of Tolañaro (Fort Dauphin)
in south-western Madagascar, the only locality from where
this genus is known.
number of seeds per fruit, and seed scar surface (Table 3). We
are therefore reluctant to include the new species in Tsebona.
The remaining option is to keep Capurodendron and Tsebona
as separate genera and to describe a new genus to accommodate
the new species from Bemangidy Forest. The key character for
this genus within the new tribe would be a brochidodromous
leaf venation with weak, parallel, and close secondaries, hard to
distinguish from the tertiaries, which is not present in any other
member of Tseboneae. It further differs from Capurodendron
by the way the external sepals impress a groove on the outer
surface of the inner ones, and by the size of the corolla which is
2.5 times larger than the corolla of the largest Capurodendron
flower. Compared with Tsebona, it also differs by the number of
stamens, the staminodes that are connivent forming a chamber
above the ovary, the number of seeds in the fruit and the percentage of the seed surface occupied by the scar. We conclude that
the new species is better accommodated in a genus of its own.

Etymology. – It is the pleasure for the author of the species
to dedicate it to the first collector of the type specimen, Porter
Prescott (Pete) Lowry II from Missouri Botanical Garden, as
an acknowledgment for all he has done for the botany of Madagascar in an unremitting spirit of collaboration.
Conservation assessment. – With an estimated Extent Of
Occurrence (EOO) of less than 10 km², an Area Of Occupancy
(AOO) of 9 km² and a single subpopulation, occurring within
a provisional protected area (Tsitongambarika), Bemangidia
lowryi is assigned a preliminary status of “Critically Endangered” (CR B1ab(iii); B2ab(iii)) following IUCN Red List Categories and Criteria (IUCN, 2001).

Note. – One specimen (Gautier 5790) collected with flower
buds in the same forest, but at higher altitude (670 m) on an
exposed ridge on the eastern summit of Ivohibe Peak, is clearly
a member of the same genus. The tree was smaller in size
(7 m) and had smaller leaves. It was first thought to be merely
an individual adapted to a more exposed site, but molecular
analysis indicates that it is also genetically different from the
type population. Until more fertile material is collected from
this population we refrain from including it in the new species.
