Abstract: 11.1.Poa sinaica subsp. pamphyliensisCabi, L. J. Gillespie & Soreng subsp. nov. Figs 6 A – G, 7 Type specimen. Turkey, Antalya, On forested plain above Varşak, Kepez district of Antalya, 227 m, old Pinus brutea forest, on limestone breaks, 227 m, 37.011078 ° N, 30.70786 ° E, 22, Apr 2015, R. J. Soreng et E. Cabi 9057 * (holotype: US- 3770798; isotypes: CAN, NAKU). Fig. 3 D, E, F illustrates the basal shoot, prophyll and ligule. Fig. 6 illustrates the plant parts; Fig. 7 is a field photo of the upper culm and inflorescence. Diagnosis. Differing from Poa sinaica subsp. sinaica by panicles open with longer branches and shorter anthers. Description. Perennials; hermaphroditic; tufted, without rhizomes or stolons, tufts moderately dense to dense, occasionally stooling with elevated bulbous shoots, 5–20 cm tall, narrow, not mat-forming, grayish green, sometimes violaceous in part; tillers intravaginal, bulbous at the base; prophylls to 1–1.8 cm long, not exerted, keels medially mixed or retrorsely scabrous, distally antrorsely scabrous; bulbs pyriform to fusiform, elongated, outermost sheaths papery, inner ones indurate at base. Culms 20–45 cm tall, erect to geniculately ascending, well exerted, terete, internodes moderately to densely muriculate to antrorsely scabrous, glabrous, 1–2 nodes exerted. Leaves basal and cauline; leaf sheaths weakly to strongly compressed, moderately scabrous, glabrous; basal sheaths 1–3 cm long, 1.5–3 mm wide, strongly imbricated; flag-leaf sheaths 4–10 cm long, margins fused 15–20 % their length, scabrous, glabrous; collars mostly scabrous, glabrous; ligules (2 –) 4–15 mm long, scarious, whitish, usually scabrous, glabrous, apices narrowly acute, often deeply lacerated to fimbriate; ligules of sterile shoots 2–4 mm long, narrowly decurrent; blades 3–20 cm long, 0.8–1.2 mm wide, blades gradually reduced upward; flag-leaf blades 1.5–7 cm long, folded to involute, filiform to slender, wiry, persistent in form, abaxially scabrous at least on the keel, and often on the surfaces, margins densely scabrous, glabrous throughout, apices narrowly prow-tipped, scabrous, sterile shoot blades like those of the culm, wiry. Panicles (3) 5–10 (– 13) cm long, ca. 1 / 6–1 / 4 the plant height, 2–5 cm wide at flowering, open, broadly ovoid to sub-pyramidal, strict to somewhat lax, moderately crowded, with 20–60 spikelets; branches (1 –) 2 (– 4) per node, scabrous; primary branches 2–4 (– 9.5 cm) long, with 6–18 (– 22) spikelets crowded in the distal 1 / 2, spreading to reflexed at flowering, and remaining open, terete to weakly angled, moderately to densely scabrous from the base; pedicels mostly less than 1 / 4 the spikelet in length. Spikelets 4–5 mm long, ovate to broadly ovate, laterally compressed, grayish-green, sometimes violaceous in part; bulbifery absent (infrequently present in x with P. bulbosa s. l., or P. sinaica var. sinaica); normal florets 4–5 (– 8); rachilla internodes mostly 0.4–0.6 mm long, muriculate, glabrous; glumes subequal, 3 - veined, narrowly lanceolate to lanceolate, subequaling the adjacent lemmas, keels distally moderately to densely scabrous, edges mostly moderately scaberulous, apices narrowly acute; lower glumes 2.5–2.8 mm, 3 - veined; upper glumes 2.5–3 mm long, up to 1 mm wide (lateral view), 3 - veined; callus glabrous (rarely with a few short hairs); lemmas 2.5–3 mm long, 3 - or obscurely 5 - veined, broadly lanceolate, green or tinged violaceous, distinctly keeled, keel and marginal veins sericate (longer hairs 0.25–0.5 mm long, blunt tipped, thicker distally, spreading in anthesis), between veins smooth or distally sparsely scabrous, glabrous or appressed sericeous in distal-most florets; intermediates to P. bulbosa s. l.?), intermediate veins faint to obscure or absent, margins proximally enrolled, distally narrowly hyaline, edges lightly to moderately scaberulous, apices obtuse, blunt or pointed; palea keels scabrous (medially sometimes short sericate), flanges ca 0.2 mm wide. Flowers bisexual, sometimes bulbiferous; lodicules 0.6 mm long, lanceolate; anthers 3, 1.3 mm long. Caryopses 1.3 mm long, brown, weekly compressed, broadly sulcate, adherent to the palea; hilum 0.3 mm long, oval. 2 n = unknown. Clade code: Aa. Distribution and ecology. Turkey. Antalya, limestone breaks above the city in old-growth Pinus brutia Ten. forest; in Turkey, 220– 230 m. Conservation status. Endemic, rare. Known only from the five cited collections from the Type locality. Probably Vulnerable based on criteria B 1 / B 2 a and D 2 ab. Threats are development, logging, grazing, and the predictable loss of habitat due to climate change. More study is needed; We observed a few dozen plants over ca. 0.5 ha at the Type locality. Similar habitat, with old-growth pines and limited soil disturbance along the bench above Antalya, should be searched. Comments. This taxon was initially considered to be a new species based on the open, long-branched panicles that distinguish it; however, the long and decurrent ligules and densely scabrous panicle branches and leaves point to P. sinaica. Further study is needed. Fig. 6 illustrates the plant. Fig. 7 is a field photograph of the plant from the Type locality. Specimens. Turkey.
