Eremopoa capillaris

HABIT Annual. Culms 18–55 cm long. Leaf-sheaths longer than adjacent culm internode. Ligule an eciliate membrane; acute. Leaf-blades 1.5–18 cm long; 0.9–1.5 mm wide. Leaf-blade surface scabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 10–20 cm long; 5–11 cm wide. Primary panicle branches ascending; 13–27 -nate; whorled at most nodes. Panicle branches capillary; scabrous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.

FERTILE SPIKELETS Spikelets comprising 1–5(–9) fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 3.5–5.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes eventually visible between lemmas.

GLUMES Glumes persistent; shorter than spikelet. Lower glume ovate; 0.8–2 mm long; 0.66–0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 1.2–2.7 mm long; 0.66–1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute.

FLORETS Fertile florets appressed to rhachilla. Fertile lemma lanceolate; oblong in profile (narrowly); 1.8–2.7 mm long; membranous; much thinner above; keeled; 5 -veined. Lemma midvein ciliolate; hairy below. Lemma surface pubescent; hairy on veins. Lemma hairs 0.2–0.3 mm long. Lemma apex truncate. Palea 1.8–2.2 mm long. Palea keels scabrous; adorned above. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3; oblong; 0.8–1 mm long.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-temperate: western Asia.

NOTES Poeae. Fl Turk 1996.
