HABIT Annual. Culms decumbent; 15–50 cm long; rooting from lower nodes. Culm-nodes glabrous, or bearded. Leaf-sheaths pilose; with tubercle-based hairs; outer margin hairy. Ligule an eciliate membrane. Leaf-blades lanceolate, or elliptic; 1–8 cm long; 2–6 mm wide. Leaf-blade surface glabrous, or hirsute. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; obovate; effuse; 2–15 cm long; bearing few spikelets. Primary panicle branches spreading.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 1–20 mm long.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets obovate; laterally compressed; compressed strongly; gibbous; 2–2.5 mm long; falling entire.

GLUMES Glumes similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 1.5–2 mm long; 0.75 length of spikelet; membranous; without keels; 3 -veined. Lower glume apex acute. Upper glume oblong; gibbous; 2 mm long; 0.75 length of spikelet; membranous; without keels; 7 -veined. Upper glume apex acute.

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; 7 -veined; obtuse. Fertile lemma obovate; laterally compressed; gibbous; 1.5–2 mm long; indurate; without keel; 5 -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; 1 mm long.

FRUIT Caryopsis with adherent pericarp.
