HABIT Perennial; caespitose. Culms erect, or geniculately ascending; 30–60 cm long. Culm-nodes glabrous. Ligule a fringe of hairs. Leaf-blades flat, or convolute; 7–15 cm long; 3–6 mm wide. Leaf-blade surface pubescent; hairy adaxially. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic; effuse; 20–35 cm long; 7–15 cm wide. Primary panicle branches 1 -nate. Panicle axis scaberulous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 10–20 mm long; scaberulous; tip widened.

FERTILE SPIKELETS Spikelets comprising 12–16 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5–6 mm long; 1.5 mm wide; breaking up at maturity; rhachilla persistent; shedding paleas.

GLUMES Glumes deciduous; similar; shorter than spikelet. Lower glume lanceolate, or elliptic; 1 mm long; 0.66 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume oblong; 1.5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma ovate; 1.5 mm long; membranous; keeled; 3 -veined. Lemma midvein scabrous. Lemma surface asperulous. Lemma apex acute. Palea 1 length of lemma. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; cuneate; fleshy. Anthers 0.4 mm long.

FRUIT Caryopsis with adherent pericarp; ellipsoid; 0.75 mm long.

DISTRIBUTION Asia-tropical: Indo-China.
