HABIT Perennial; caespitose. Culms slender; 30–55 cm long. Culm-nodes glabrous. Leaf-sheaths hispid; with tubercle-based hairs. Ligule an eciliate membrane; 0.2–0.5 mm long; erose. Leaf-blades flat, or involute; 8–18 cm long; 3–6 mm wide. Leaf-blade surface hispid; sparsely hairy; hairy on both sides.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear, or lanceolate; 8–20 cm long. Primary panicle branches 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; 3–3.5 mm long; falling entire. Spikelet callus bearded; base obtuse. Spikelet callus hairs 1–2 mm long.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 3–3.5 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 6–15 mm long. Upper glume lanceolate; 3–3.5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 6–15 mm long.

FLORETS Fertile lemma oblong; 3–3.5 mm long; cartilaginous; dark brown; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex dentate; 2 -fid; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; flat below; 12–26 mm long overall; with twisted column. Lateral lemma awns arising on apex of lobes; 1–1.5 mm long. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.

FLOWER Lodicules 2; cuneate; fleshy.

DISTRIBUTION Asia-tropical: India.
