HABIT Perennial; caespitose. Culms erect; 60–165 cm long. Culm-nodes pubescent. Leaf-sheaths glabrous on surface, or pubescent. Ligule a ciliolate membrane; 0.3–0.5 mm long. Leaf-blades flat, or conduplicate; 20–60 cm long; 5–9(–12) mm wide. Leaf-blade surface glabrous, or hirsute; sparsely hairy; with simple hairs, or tubercle-based hairs.

INFLORESCENCE Inflorescence a panicle.

Panicle open; lanceolate; 25–45(–60) cm long. Primary panicle branches ascending, or spreading; 3–15 cm long; bearing spikelets almost to the base.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3–5 mm long; falling entire. Spikelet callus glabrous, or pubescent; base obtuse.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 3–5 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex acute, or acuminate; muticous, or awned; 1 -awned. Lower glume awn 0–7 mm long. Upper glume lanceolate; 3–5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute, or acuminate; muticous, or awned; 1 -awned. Upper glume awn 0–7 mm long.

FLORETS Fertile lemma oblong; 3–5 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex muticous, or awned; 1 -awned. Principal lemma awn straight, or flexuous; 0–15 mm long overall; without a column. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.

FLOWER Lodicules 2; cuneate; fleshy.

DISTRIBUTION Asia-temperate: China. Asia-tropical: India, Indo-China, and Malesia.
