Jamzad* Abstract Satureja rechingeri (Labiatae) is described as a new species from Iran, and its relationship to S. khuzistanica, S. edmondi and 5. macrantha discussed. The new species is characterized by its yellow flowers, dense white villous hairs and a dense covering of punctate glands on both leaf surfaces. It grows in Ham province in west Iran. Key Words: Flora of Iran; Labiatae, Satureja, S. rechingeri sp.n. Zusammenfassung Satureja rechingeri (Labiatae) wird neu beschrieben, die Unterschiede zu S. khuzistanica, S. edmondi und 5. macrantha werden diskutiert. Die neue Art aus der Harn Provinz in Iran wird durch gelbe Blüten, dichte zottige Behaarung und eine dichte Punktierung mit Drüsen auf beiden Blattseiten charakterisiert. Introduction In autumn 1994, the author collected Satureja species in the western part of the country in Ham province. In this excursion a highly aromatic specimen was found; its characters did not match any of the Iranian taxa or other specimens studied before at TARI, G and W. Therefore it is described as new species. Results and discussion in Flora Iranica (1982) reported 14 species from this area, 11 of which were in Iran, 5 as endemics. Since the publication of the Flora Iranica account S. kallarica JAMZAD, and S. khuzistanica JAMZAD have been described (JAMZAD 1992,1994), bringing, together with the new one described here, the total of Iran species to 14. They are mainly distributed in the west of the country with a few in the north. RECHINGER Satureja rechingeri JAMZAD sp.n. Suffrutex, valde aromaticus, a basi ramosus; caules ± 50 cm alti.

Bracteae lanceolatae 2 - 3.5 mm longae. Calyx 6.5 - 8 mm longus, tubuloso-campanulatus, bilabiatus; dentés superiores trianguläres, acuti, 2 mm longi, inferiores lanceolati, 3 mm longi. Corolla 1 3 - 1 5 mm longa, flava, labiis purpureo-suffusis. Stamina corollae fauce vix exserta. Semina ignota. (Fig. 1). Typus: (Iran,) Ilam (province), Ilam to Mehran, Ban-e Roushan, 900 m; Jamzad, Mazhari & Ahmadi, 75587 [holotypus TARI]. Subshrub, strongly scented, branched from base; stem ± 50 cm high; all parts covered by dense, white villose hairs. Stem leaves 9 - 1 3 x 7 - 1 1 mm, broadly obovate or orbicular, abruptly attenuate at the base into a 1 mm long petiole, densely covered with punctate glands on both surfaces. Lower leaves flat, upper leaves gently curved inwards to the apex. Cymes pedunculate, 2 - 8-flowered, forming a ± dense interrupted spike; peduncles 2 - 6 mm long. Bracts lanceolate, 2 - 3 . 5 mm long. Calyx 6.5 - 8 mm, tubulose-campanulate, bilabiate; upper teeth triangular, 2 mm long, acute, lower teeth 3 mm long. Corolla 13-15 mm long, yellow, the lips tinged purple. Stamens 4, slightly exserted from the corolla tube. Seeds not seen. The new species is found on dry stony slopes on river banks. It is close to S. khuzistanica JAMZAD, S. edmondi BRIQ. and S. macrantha C.A.MEY. S. khuzistanica differs in having ± imbricate, decussate leaves with short internodes, a shortly pubescent indumentum, the inflorescence of shortly pedunculated verticillasters and violet corollas. S. edmondi differs in having oblong-lanceolate leaves, a shortly pubescent indumentum, the inflorescensce of subsessile ± approximating verticillasters and violet corollas. S. macrantha differs in having linear-spathulate leaves, a scabrid, retrorse indumentum and mauve corollas. Acknowledgments I wish to thank Dr Ernst Vitek for editing the paper, Mr I.C.
