HABIT Perennial; caespitose; clumped densely. Culms erect; slender; 12–20(–30) cm long; 0.5 mm diam.; 2–3 -noded. Leaf-sheaths mostly shorter than adjacent culm internode. Ligule an eciliate membrane; 0.5 mm long; truncate, or obtuse. Leaf-blades flat, or involute; 3–15 cm long; 1–2 mm wide.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; lanceolate; 3–8 cm long. Primary panicle branches 2–6 -nate; whorled at most nodes; 2–4 cm long. Panicle branches smooth, or scaberulous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 2.5–3.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent. Floret callus hairs 0.2 mm long.

GLUMES Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; shiny; gaping. Lower glume lanceolate; 2.8–3.5 mm long; 1 length of upper glume; membranous; purple; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 2.5–3.2 mm long; 1.2–1.5 length of adjacent fertile lemma; membranous; purple; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma elliptic; 2 mm long; hyaline; without keel; 5 -veined. Lemma apex erose; awned; 1 -awned. Principal lemma awn dorsal; arising 0.5 way up back of lemma; geniculate; 3.5–5 mm long overall; with a straight or slightly twisted column. Palea 0.4–0.6 mm long; 0.2–0.5 length of lemma; hyaline.

FLOWER Anthers 3; 0.6–0.8 mm long.

DISTRIBUTION Asia-temperate: China.
