HABIT Perennial; caespitose; clumped loosely. Culms erect; 35–40 cm long. Ligule an eciliate membrane; 2–3.5 mm long; obtuse. Leaf-blades 10 cm long; 3–4 mm wide.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 10–15 cm long; 1–2 cm wide. Primary panicle branches appressed. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 2.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.

GLUMES Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; shiny; gaping. Lower glume lanceolate; 2.5 mm long; 1.2 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 2 mm long; 1.2–1.4 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma oblong; 1.5–2 mm long; hyaline; without keel; 5 -veined. Lemma lateral veins extending close to apex. Lemma apex truncate; awned; 1 -awned. Principal lemma awn dorsal; arising 0.5 way up back of lemma; geniculate; 2–2.5 mm long overall; with twisted column. Palea hyaline.

FLOWER Lodicules 2; membranous. Anthers 3; 0.6–0.7 mm long.

FRUIT Caryopsis with adherent pericarp. Hilum linear.

DISTRIBUTION Asia-temperate: Siberia and Soviet far east.
