New and noteworthy records for the flora of Yemen, chiefly of Hadhramout and Al-Mahra

Abstract Kilian, N., Hein, P. & Hubaishan, M. A.: New and noteworthy records for the flora of Yemen, chiefly of Hadhramout and Al-Mahra. — Willdenowia 32: 239–269. 2002. — ISSN 0511-9618. Based on own collections made in the southern governorates of the Republic of Yemen between 1997 and 2002, 110 new and noteworthy records of vascular plants are provided. Five taxa, Iphigenia oliveri, Kleinia squarrosa, Parthenium hysterophorus, Rhus glutinosa subsp. neoglutinosa and Poskea socotrana are recorded as new for the Arabian Peninsula, and Pistacia aethiopica is confirmed; 23 species are recorded as new and four are confirmed for mainland Yemen; 77 species are recorded as new for the southern governorates of Yemen or larger parts of them. Brief comments are given on the phytogeography of the taxa. Rhus flexicaulis, a species hitherto considered an endemic of SW Arabia, is found conspecific with the widespread African R. vulgaris, and provides, for priority reasons, the correct name for this species; the most recently described R. gallagheri from Oman is also conspecific with it. Justicia areysiana is accepted as the correct name for the S Arabian endemic formerly known as Bentia fruticulosa.

Arabis lycia (Cruciferae), a new chasmophyte from the Taurus Mts, Turkey, and notes on related species

Abstract Parolly, G. & Hein, P.: Arabis lycia (Cruciferae), a new chasmophyte from the Taurus Mts, Turkey, and notes on related species. — Willdenowia 30: 293–304. 2000. — ISSN 0511-9618. Arabis (sect. Drabopsis) lycia is described as a species new to science and illustrated, and its taxonomic position close to A. bryoides of the S Balkans is discussed. SEM micrographs of the indumentum of A. lycia and its relatives (A. bryoides, A. carduchorum, A. drabiformis) are presented and their ecological requirements outlined. The new species is a subalpine cushion-forming plant of shaded vertical limestone rocks along the ridge of the Bakirli Daği in the eastern part of the Western Taurus in Turkey. The chasmophytic habit and its stenochory suggests that A. lycia should be included in the list of relic endemics known from the mountains W of the Bay of Antalya.

A new species of Campylanthus (Scrophulariaceae) from Ras Fartak, Al-Mahra, and notes on other species of the genus in Yemen

Abstract Kilian, N., Hein, P. & Bahah, S. O.: A new species of Campylanthus (Scrophulariaceae) from Ras Fartak, Al-Mahra, and notes on other species of the genus in Yemen. — Willdenowia 32: 271–279. 2002. Campylanthus hubaishanii, a dwarf shrub from the coastal mountains of southeastern Yemen, is described as a species new to science and illustrated. It is the fifth species of the genus known from mainland Yemen. The new species is compared and a closer relationship suggested with C. sedoides from coastal Jiddat al Harasis, central Oman. Based on collections made by the authors during the last years, new data on the distribution and variation of C. antonii, C. junceus and C. pungens in Yemen are also provided.

Studies in the Compositae of the Arabian Peninsula and Socotra — 2. Pulicaria samhanensis sp. nova (Inuleae) from Dhofar and notes on other S Arabian species of the genus

Abstract Kilian, N. & Hein, P.: Studies in the Compositae of the Arabian Peninsula and Socotra — 2. Pulicaria samhanensis sp. nova (Inuleae) from Dhofar and notes on other S Arabian species of the genus. — Willdenowia 29: 187–196. 1999. — ISSN 0511-9618. Pulicaria samhanensis from Jabal Samhan, E Dhofar, Oman, is described as a species new to science and illustrated. The species is most remarkable for its purple flowered, disciform, heterogamous capitula and its achene wall with a single layer of sclerenchymatous cells. The news species is closely related to P. pulvinata from coastal Jiddat al Harasis, Central Oman, and both hold a rather isolated position in the genus. The S Arabian distribution and infraspecific variation of P. (sect. Platychaete) argyrophylla is re-evaluated and P. argyrophylla var. oligophylla raised to subspecies rank. P. (sect. Platychaete) omanensis is for the first time reported from Yemen and P. rauhii is found to be conspecific with the former.

Poa akmanii (Poaceae), a new species from Turkey

Abstract Soreng, R. J., Hein, P. & Scholz, H.: Poa akmanii (Poaceae), a new species from Turkey. — Willdenowia 27: 195–198. 1997. — ISSN 0511-9618. The discovery of a new grass species in the Western Toros range in SW Anatolia is reported. Poa akmanii, belonging to the Poa bulbosa complex, is described as a species new to science, illustrated and compared to Poa timoleontis, Poa pelasgis and Poa trichophylla.
