HABIT Perennial; caespitose; clumped moderately. Rhizomes short; pachymorph. Culms erect; erect at the tip; 200–400 cm long; woody; without nodal roots. Culm-internodes terete; hollow; ridged; distally pruinose. Culm-nodes flush with internodes; glabrous. Lateral branches dendroid. Bud prophyll 1-keeled. Branch complement three; subtended by a bare patch above the node; with subequal branches; thinner than stem. Culm-sheaths glabrous, or pubescent; hairy above; auriculate; with obtuse auricles; with 1 mm high auricles; glabrous on shoulders. Culm-sheath ligule 1–2 mm high; ciliate. Culm-sheath blade lanceolate; demarcated but persistent; erect, or reflexed; 2–10 cm long; 3–5 mm wide; pubescent. Leaf-sheaths glabrous on surface; outer margin glabrous. Leaf-sheath oral hairs lacking. Ligule an eciliate membrane; 1.5 mm long; truncate. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 7–9 cm long; 6–8 mm wide. Leaf-blade venation with distinct cross veins.

INFLORESCENCE Inflorescence a panicle.

Panicle branches bearded in axils; with insignificant pulvini.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 10–20 mm long.

FERTILE SPIKELETS Spikelets comprising 3–6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 30–40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes flattened; 5–6 mm long; pubescent and pilose; hairy all along but hairs longer above.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 6–11 mm long; chartaceous; without keels. Lower glume apex acute; awned. Upper glume elliptic; 8–14 mm long; 0.6–0.8 length of adjacent fertile lemma; chartaceous; without keels. Upper glume apex acute; awned.

FLORETS Fertile lemma 13–17 mm long; chartaceous; without keel. Lemma surface pubescent. Palea 10–12 mm long; 2 -veined. Palea keels ciliolate; adorned above; with 0.5 of their length adorned; with hairs 0.3 mm long. Palea surface scabrous. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 3; ciliate. Anthers 3; yellow. Stigmas 2–3.

FRUIT Caryopsis with adherent pericarp; apex unappendaged.

DISTRIBUTION Asia-tropical: India.
