3.2. 1.Poa bulbosa subsp. perligulataH. Scholzvar. perligulata(H. Scholz), Soreng & Cabi, stat. et comb. nov. ≡ Poa perligularis H. Scholz, Willdenowia 16 (2): 404. 1987. (nom. nov., non. P. perligulata Pilg., 1833). ≡ Poa bulbosa subsp. perligulata H. Scholz, Bot. Chron. 3 (1–2): 17, f. 1 c – d. 1983 b. Type specimen. Italia, Insula Elba, Marina di Campo, 12 Apr 1980, W. Lang s. n. (holotype: B [B 100108623]). Description. Perennials; hermaphroditic; tufts dense; tillers intravaginal; prophyll keels elongated, included or exerted from basal sheaths, keels mainly retrorsely scabrous or medially mixed-directional and distally antrorsely scabrous; bulbs 2–3 cm long, narrow pyriform to fusiform. Culms (20 –) 30–50 cm tall, erect or spreading, smooth. Leaves mostly basal, with few culm leaves; leaf sheaths strongly imbricated at base; flag-leaf sheaths 5–8 cm long; ligules of culm leaves (5 –) 6–8 + mm long, longer than the blade is wide, sub-hyaline, or watery-white, smooth or scabrous, apices acute-acuminate, entire; ligules of sterile shoots 2–6 mm; basal blades, slender to (0.5 –) 1–1.5 mm wide; blades of culm 2–8 (– 15) cm long, 1.5–2 (– 3.5) mm wide, blades equal or gradually reduced upward, thin, flat or shallowly folded, withering in age; flag-leaf blade 2–4 cm long; sterile shoot blades (1.5 –) 4–10 (– 15) cm long, (0.5 –) 1–1.5 mm wide. Panicles 4.5–6 cm long, erect, ovoid to fusoid, contracted (open in anthesis), fairly crowded, well exerted at maturity axis with 2–4 branches at the lowest node; primary branches erect to ascending, moderately rigid, moderately to densely scabrous. Spikelets (4.5 –) 5–6 (– 6.5) mm long, ovate to oblong, compact, laterally compressed, proliferation absent; florets (3 –) 4–6 (– 7), normal; rachilla internodes mostly 0.4–0.5 mm long, smooth or sparsely scaberulous, glabrous, sightly exposed or not; glumes slightly unequal or subequal, distinctly keeled, keels distally scabrous, distinctly arched, edges sparsely to moderately scaberulous, apices acute to narrowly acute; lower glumes 3.0– 3.2 mm long, 1 (– 3) - veined; upper glumes 3.5–3.7 mm long, 3 - veined; callus hairs scant and short to several and longer than their lemmas; lemmas (2.8 –) 3–3.5 mm long, 3 - or 5 - veined, narrowly ovate, distinctly keeled, keel and marginal veins pubescent, intermediate veins faint to obscure, apices obtuse to acute, pointed; palea keels scabrous distally, proximally or up to medially ciliate, hairs 0.15–0.3 mm long. Flowers all normal; anthers (0.9 –) 1–1.8 mm long. 2 n = unknown. Clade code: Aa. Distribution and ecology. Reported by Euro + Med Plant Base from Algeria, Cyprus, Greece, Italy, Morocco, Spain, Tunisia, and by Portal (2005) from France (Corsica only?), and here from Turkey (European part). Mesic sandy ground on coastal plains and low elevation valleys; in Turkey, 180– 200 m. Conservation status. None. Needs further study. Comments. These are the first reports for Turkey. The taxon is reported as a species or subspecies in various accounts (Portal 2005; Dobignard and Chatelain 2010; and others), but without further study RJS considers it can only be treated as a subspecies or variety within Poa bulbosa. Portal (2005) accepted and illustrated this as a species but doubted its distinctness from P. bulbosa. Ortega Olivencia (2020) included it in P. bulbosa without comment. Scholz (1983 b) cited seven collections from Cyprus, Greece, Spain, and Tunisia. Representative specimens. Turkey. İstanbul (West) (Dune of Terkos Tree Nursery, 3 May 1971, A. Baytop, G. Ertem and N.
