HABIT Perennial. Rhizomes elongated. Culms erect; 15–33 cm long; 2 -noded. Culm-internodes smooth; distally glabrous. Leaf-sheaths glabrous on surface, or puberulous; outer margin hairy (below). Ligule an eciliate membrane; 2–4 mm long; obtuse. Leaf-blades 2–6 cm long; 2–6 mm wide; glaucous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle; subtended by an inflated leaf-sheath.

Panicle spiciform; oblong; 2.5–3 cm long; 0.7–1 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis. Panicle axis with rounded ribs.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 5–7 mm long; falling entire.

GLUMES Glumes connate along margins below; 0.15 of their length connate; similar; exceeding apex of florets; recurved at apex. Lower glume lanceolate; 5–7 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume primary vein ciliate. Lower glume apex acuminate. Upper glume lanceolate; 5–7 mm long; 1.2–1.4 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein ciliate. Upper glume apex acuminate.

FLORETS Fertile lemma ovate; 4–5 mm long; membranous; keeled; 5 -veined. Lemma margins connate below; with 0.5 of their length connate. Lemma apex acute; awned; 1 -awned. Principal lemma awn dorsal; arising 0.5 way up back of lemma; straight, or curved; 5–6.5 mm long overall; with a straight or slightly twisted column. Palea 3 mm long; 0.6–0.75 length of lemma; 1 -veined.

FLOWER Lodicules absent. Anthers 3; 3 mm long; yellow.

FRUIT Disseminule comprising a spikelet.

DISTRIBUTION Asia-temperate: western Asia.

NOTES Aveneae. Dogan 2003.
