HABIT Perennial. Culms geniculately ascending, or rambling; 50–120 cm long; rooting from lower nodes. Culm-nodes glabrous, or bearded. Leaf-sheaths glabrous on surface, or pilose; with tubercle-based hairs. Ligule an eciliate membrane. Leaf-blades lanceolate, or elliptic; 6–25 cm long; 5–20 mm wide. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; obovate; 5–35 cm long. Primary panicle branches 4–8 in number; drooping.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; angular; 5–25 mm long; scabrous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets obovate; laterally compressed; compressed strongly; gibbous; 1.5–2 mm long; falling entire.

GLUMES Glumes similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate, or ovate; 1.2 mm long; 0.75 length of spikelet; membranous; without keels; 3 -veined. Lower glume apex acuminate. Upper glume oblong; gibbous; 1.5–2 mm long; 1 length of spikelet; membranous; without keels; 5–7 -veined. Upper glume apex cuspidate.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; oblong; 1.5–2 mm long; 1 length of spikelet; membranous; 5 -veined; ciliolate on margins; fringed above; cuspidate. Fertile lemma obovate; laterally compressed; gibbous; 1.5–2 mm long; indurate; shiny; without keel; 5–7 -veined. Lemma lateral veins obscure. Lemma margins involute. Lemma apex with a little green crest. Palea reflexed at apex; involute; indurate; 2 -veined.

FLOWER Anthers 3; 0.5–1 mm long.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-tropical: India and Indo-China.
