11.3. 1.Poa sinaica subsp. sinaica var. glabrescensFeinbrun., Bull. Misc. Inform. Kew. 7 (1940): 283. 1940. = Poa sinaica subsp. moabitica Feinbrun, Bull. Misc. Inform. Kew 7 (1940): 283. 1940. Type specimen. Palestine: Moab, Ziza to Um el Ammund; 1929 [15 Apr], Eig et Zohary s. n. (lectotype, here designated: HUJ [photo at K (rjs rjsr 5781. jpg)]; isolectotype: K [K 000939202]). Note. This is a tall plant with a somewhat diffuse panicle. Lemmas glabrous, branches smooth and terete below, sparse to moderately scabrous distally, ligules long and decurrent, sheaths obscurely scabrous. Feinbrun later put this in synonymy of var. glabrescens (Feinbrun 1986 a, p. 247). Type. Palestine • Edom, 23 km SW of Ma’an, {30 Mar} 1936, A. Eig, N. Feinbrun et M. Zohary s. n. (lectotype here designated: HUJ {n. v.}; isolectotype: K [K 000641312]). Diagnosis. Like subspecies sinaica, but lemmas glabrous. Distribution and ecology. Israel, Turkey. Semiarid habitats, Negev Desert steppe, and mountain slopes to the low alpine zone; in Turkey, 2,400 –2,500 m. Conservation status. None. Comments. This is the first report for Turkey. It differs from P. bactriana s. s. and s. l. in having long and decurrent ligules. The Type of var. glabrescens is a short and compact plant (like the specimen from Turkey) compared to the taller and open-panicled Type of var. moabitica. The glabrous form seems to be a trivial variation but is worth tracking until we know more. Representative specimen. Turkey. Erzurum (Kargapazari Daği, 23 Jul 1991, Zengin 102 ISTE 65237). Kayseri (Soreng et al. 8130 - a).
