HABIT Annual; culms solitary. Culms erect, or geniculately ascending; 3–12 cm long. Culm-nodes pubescent. Leaves distichous. Leaf-sheaths pilose; outer margin hairy. Ligule a ciliolate membrane; 0.1–0.2 mm long. Leaf-blades 2–3 mm wide. Leaf-blade surface glabrous.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; oblong; multilateral; 0.5–1.6 cm long; 0.4–1 mm wide. Spikelet packing broadside to rhachis; crowded.

Spikelets solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 5–12 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 4–7 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume elliptic; 2–2.6 mm long; chartaceous; 1-keeled; 5–7 -veined. Lower glume surface pilose. Lower glume apex acute. Upper glume elliptic; 2–2.6 mm long; 0.7–0.8 length of adjacent fertile lemma; chartaceous; 1-keeled; 5–7 -veined. Upper glume surface pilose. Upper glume apex acute.

FLORETS Fertile lemma lanceolate, or ovate; 2.6–3.2 mm long; chartaceous; keeled; 9–11 -veined. Lemma surface pilose; hairy below. Lemma margins ciliate. Lemma apex acute; mucronate. Palea 1 length of lemma; hyaline; 2 -veined. Palea keels ciliate; adorned below; with 0.33 of their length adorned. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; cuneate; fleshy. Anthers 3; 1.2–1.6 mm long.

FRUIT Caryopsis with adherent pericarp. Disseminule comprising a floret.

DISTRIBUTION Asia-temperate: Soviet Middle Asia.
