HABIT Perennial. Culms decumbent, or rambling; slender; 60–120 cm long. Culm-nodes glabrous, or bearded. Leaf-sheaths glabrous on surface, or hispid. Leaf-sheath oral hairs bearded; 1.5–4 mm long. Ligule an eciliate membrane. Leaf-blades 5–16 cm long; 3–8 mm wide; membranous. Leaf-blade surface glabrous, or hirsute; hairy on both sides.

INFLORESCENCE Inflorescence a panicle.

Panicle open, or contracted; linear to elliptic; 4–15 cm long. Primary panicle branches bearing spikelets almost to the base. Panicle branches smooth.

Spikelets ascending; solitary. Fertile spikelets pedicelled. Pedicels smooth.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 2.6–5 mm long; falling entire. Spikelet callus pubescent; base obtuse.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 2.6–5 mm long; 1 length of upper glume; membranous; 1-keeled; 3–5 -veined. Lower glume surface glabrous, or hispid. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 2–5 mm long. Upper glume lanceolate; 2.6–5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3–5 -veined. Upper glume surface glabrous, or hispid. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 2–5 mm long.

FLORETS Fertile lemma oblong; 2.6–5 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; straight, or curved; ascending, or reflexed; flat below; 5–9 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-tropical: India.
