HABIT Perennial; caespitose; clumped loosely. Culms erect; 30–60 cm long; 2–3 -noded. Leaf-sheaths glabrous on surface, or puberulous. Ligule an eciliate membrane; 1.5–2 mm long; entire, or lacerate; truncate. Leaf-blades convolute; 13–25 cm long; 2–3 mm wide. Leaf-blade surface glabrous.

INFLORESCENCE Inflorescence a panicle. Peduncle pubescent above.

Panicle spiciform; lanceolate; interrupted; loose; 5–11 cm long; 1.5–4 cm wide. Panicle axis pubescent. Panicle branches pubescent.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels pubescent.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 4–5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.

GLUMES Glumes persistent; similar; shorter than spikelet; similar to fertile lemma in texture; shiny; gaping. Lower glume lanceolate; 2.5–3 mm long; 0.7–0.8 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume oblong; 3–3.5 mm long; 0.75–0.85 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma oblong; 3.5–4.5 mm long; membranous; shiny; keeled. Lemma midvein scabrous. Lemma apex acuminate. Palea gaping. Palea keels ciliolate.
