HABIT Perennial. Rhizomes elongated. Culms erect, or geniculately ascending; 75–110 cm long. Leaf-sheaths tubular for much of their length; with 1 of their length closed; smooth; glabrous on surface, or hispid. Ligule an eciliate membrane; 0.5–1 mm long; truncate. Leaf-blades flat, or convolute; 20–35 cm long; 3.5–11 mm wide. Leaf-blade surface scaberulous; glabrous, or hispid.

INFLORESCENCE Inflorescence a panicle.

Panicle open; 30–35 cm long. Primary panicle branches ascending; distant; 7–12 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 6.5–8 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2 mm long.

GLUMES Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate, or elliptic; 2.5–3.3 mm long; 0.66 length of upper glume; membranous; without keels; 5 -veined. Lower glume apex acute. Upper glume lanceolate, or elliptic; 4–5 mm long; 0.9 length of adjacent fertile lemma; membranous; without keels; 5 -veined. Upper glume apex acute.

FLORETS Fertile lemma elliptic, or oblong; 4.5–5.5 mm long; chartaceous; much thinner above; without keel; 7 -veined. Lemma lateral veins prominent. Lemma surface scaberulous. Lemma apex obtuse, or acute. Palea 2 -veined. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; united; oblong; fleshy; truncate. Anthers 3.

FRUIT Caryopsis with adherent pericarp. Hilum linear.

DISTRIBUTION Asia-temperate: China and eastern Asia. Asia-tropical: India.
