Leaf-sheaths open for most of their length; with 0.25–0.33 of their length closed; glabrous on surface. Ligule an eciliate membrane; 0.5 mm long. Leaf-blades filiform; conduplicate; elliptic in section; 0.5–1 mm wide. Leaf-blade venation comprising 7 vascular bundles; with 1–3 inner ridges. Leaf-blade surface scabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 3–5 cm long. Panicle axis scabrous. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

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

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 3.6–4 mm long; 0.75 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume lanceolate; 4–5 mm long; 1 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume margins scabrous. Upper glume apex obtuse.

FLORETS Fertile lemma oblong; 4–5 mm long; chartaceous; light brown; without keel; 5 -veined. Lemma midvein scabrous. Lemma lateral veins obscure. Lemma surface scabrous; rough on veins. Lemma apex obtuse; awned; 1 -awned. Principal lemma awn 1.5–2.5 mm long overall. Palea 2 -veined. Palea keels scabrous; adorned above. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2. Anthers 3; 2–2.5 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp. Hilum linear.

DISTRIBUTION Asia-temperate: Siberia, Soviet Middle Asia, China, and Mongolia.
