HABIT Perennial; caespitose; clumped loosely. Culms erect; 30–35 cm long. Culm-internodes antrorsely scabrous. Lateral branches lacking. Leaf-sheaths smooth; glabrous on surface. Ligule an eciliate membrane; 1–2 mm long; entire, or lacerate; truncate. Leaf-blades flat, or convolute; 1–3.5 cm long; 1 mm wide. Leaf-blade surface scabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; lanceolate; 3–6 cm long; 1–1.5 cm wide.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus woolly.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 3–4 mm long; membranous; 1-keeled. Lower glume apex acute. Upper glume ovate; 3–4 mm long; membranous; 1-keeled. Upper glume apex acute.

FLORETS Fertile lemma ovate; 4 mm long; membranous; keeled; 5 -veined. Lemma midvein ciliate. Lemma lateral veins distinct. Lemma surface pubescent; hairy below. Lemma margins ciliate. Lemma apex acute. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
