HABIT Annual. Culms erect, or geniculately ascending; weak; 15–50 cm long. Culm-nodes glabrous, or pubescent. Ligule an eciliate membrane; truncate. Leaf-blades straight, or flexuous; flat, or involute; 2–10 cm long; 1–1.5 mm wide. Leaf-blade apex obtuse.

INFLORESCENCE Inflorescence a panicle.

Panicle spiciform; linear, or oblong; 0.75–1.5 cm long; 0.2–0.4 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 0.3–0.7 mm long; scaberulous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; gibbous; obtuse, or acute; 1.2–1.5 mm long; falling entire.

GLUMES Glumes reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.75 mm long; 0.5 length of spikelet; hyaline; without keels; 3 -veined. Lower glume apex obtuse, or acute. Upper glume elliptic, or ovate; gibbous; 1.5 mm long; 1.5 length of adjacent fertile lemma; 1 length of spikelet; membranous; without keels; 7–9 -veined. Upper glume lateral veins ribbed. Upper glume surface pubescent. Upper glume apex obtuse.

FLORETS Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 7 -veined; ribbed; pubescent; obtuse. Palea of lower sterile floret 0.4 length of lemma. Fertile lemma elliptic; dorsally compressed; 1 mm long; chartaceous; pallid; shiny; without keel. Lemma margins involute. Lemma apex acute. Palea involute; chartaceous.

FRUIT Caryopsis 0.8 mm long.

DISTRIBUTION Asia-tropical: Indo-China.
