Leaves without demarcation between sheath and blade. Leaf-sheaths keeled; outer margin hairy. Leaf-sheath oral hairs ciliate. Ligule a ciliate membrane; 0.3–1 mm long. Leaf-blades flat, or conduplicate, or involute; 20–60 cm long; 2–6 mm wide. Leaf-blade margins scabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; lanceolate; 35–70 cm long. Primary panicle branches 8–20 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 pubescent; base obtuse. Spikelet callus hairs 0.3–0.5 mm long.

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 surface scabrous; rough on veins. Lower glume apex acute to setaceously attenuate. Upper glume lanceolate; 3–5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume surface scabrous; rough on veins. Upper glume apex acute to setaceously attenuate.

FLORETS Fertile lemma oblong; 3–4 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn curved; spreading and recurved at base of limb; 3.5–6 mm long overall. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.

FLOWER Lodicules 2; cuneate; fleshy.
