HABIT Annual. Culms weak; 8–20 cm long. Culm-nodes bearded. Leaf-sheaths glabrous on surface, or hispid. Ligule an eciliate membrane; 0.3–0.5 mm long. Leaf-blades flat, or conduplicate; 3–7 cm long; 1.5–3 mm wide; membranous. Leaf-blade surface glabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; lanceolate; 3–8 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; 2–2.8 mm long; falling entire. Spikelet callus pubescent; base obtuse.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 2–2.8 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume surface scabrous. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 3–6 mm long. Upper glume lanceolate; 2–2.8 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume surface scabrous. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 3–6 mm long.

FLORETS Fertile lemma oblong; 2–2.8 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 16–22 mm long overall; with a straight or slightly twisted 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-tropical: India.
