HABIT Perennial. Butt sheaths papery. Culms 30–60 cm long. Culm-nodes glabrous. Ligule an eciliate membrane; 1.5–7 mm long. Leaf-blades 10–22 cm long; 2 mm wide. Leaf-blade surface scaberulous; rough on both sides; glabrous. Leaf-blade margins scabrous. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic; 8–16 cm long. Primary panicle branches 3–4 -nate. Panicle branches flexuous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3–4.5 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; shiny; gaping. Lower glume lanceolate; 3–4.5 mm long; 1 length of upper glume; membranous; 1-keeled; keeled above; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 3–4.5 mm long; 1.4–1.5 length of adjacent fertile lemma; membranous; 1-keeled; keeled above; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma oblong; 2–2.5 mm long; cartilaginous; without keel; 5 -veined. Lemma lateral veins excurrent. Lemma margins ciliate. Lemma apex awned; 1 -awned. Principal lemma awn dorsal; arising 0.1 way up back of lemma; geniculate; 5 mm long overall; with twisted column. Palea 2 mm long; 0.8–1 length of lemma; hyaline.

FLOWER Lodicules 2; membranous. Anthers 3; 1.3–1.5 mm long.

FRUIT Caryopsis with adherent pericarp. Hilum linear.

DISTRIBUTION Asia-tropical: Indo-China.
