Oreopoa anatolica

HABIT Perennial; caespitose; clumped densely. Culms erect; 9–13(–15) cm long; 0.5–0.8 mm diam.; 1–2 -noded. Culm-internodes striate; distally glabrous. Leaves mostly basal. Ligule an eciliate membrane; 0.2–0.6 mm long; erose. Leaf-blades filiform, or linear; convolute; 15–30 cm long; 0.5–1 mm wide; stiff; grey-green. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; pyramidal; 3–6 cm long; 2–5 cm wide; bearing few spikelets; with spikelets clustered towards branch tips. Primary panicle branches spreading; 1–3 -nate; 1–2.5 cm long; bearing 1–3 fertile spikelets on each lower branch. Panicle branches flexuous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–5(–6) fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; (4–)5–7(–8) mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet; similar to fertile lemma in texture. Lower glume elliptic; 2–2.5 mm long; 0.75 length of upper glume; membranous; much thinner on margins; without keels; 1(–3) -veined. Lower glume lateral veins absent. Lower glume apex erose; acute. Upper glume elliptic; 2.5–3.5 mm long; 1 length of adjacent fertile lemma; membranous; with hyaline margins; without keels; 3 -veined. Upper glume apex erose; obtuse.

FLORETS Fertile lemma elliptic; 2.5–3.5 mm long; membranous; much thinner on margins; purple; without keel; 5(–7) -veined. Lemma apex erose; acute. Apical sterile florets resembling fertile though underdeveloped.

DISTRIBUTION Asia-temperate: western Asia.
