Ligule an eciliate membrane, or a ciliolate membrane; 0.2–1.5 mm long. Collar pilose, or bearded. Leaf-blades flat, or convolute; 7–20 cm long; 2–6(–8) mm wide. Leaf-blade surface hispid; hairy adaxially, or on both sides.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 6–15 cm long. Primary panicle branches bearing spikelets almost to the base.

Spikelets in pairs. Fertile spikelets pedicelled. Pedicels unequal.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3–4.5 mm long; falling entire. Spikelet callus pilose; base obtuse. Spikelet callus hairs 0.3–1 mm long.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 3–4.5 mm long; 1.1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume surface scabrous; rough on veins. Lower glume apex acute, or acuminate; muticous, or awned; 1 -awned. Lower glume awn 0–7 mm long. Upper glume lanceolate; 2.8–4.2 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; 2.8–4.2 mm long; cartilaginous; without keel; 3 -veined. Lemma surface glabrous, or pubescent; hairy at base. Lemma margins involute; interlocking with palea keels. Lemma apex awned; 1 -awned. Principal lemma awn straight, or flexuous; 6–15(–20) 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 and eastern Asia. Asia-tropical: India, Indo-China, and Malesia. Pacific: north-central.
