Leaf-sheaths smooth; glabrous on surface. Ligule an eciliate membrane; 1–3 mm long; obtuse. Leaf-blades 8–12 cm long; 2–3 mm wide. Leaf-blade margins scabrous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 8–12 cm long; 2–4 cm wide. Primary panicle branches 1–2 -nate; bearing 1–6 fertile spikelets on each lower branch. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 7–10 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8–12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus woolly.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 4 mm long; 0.75 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume primary vein scabrous. Lower glume apex acute. Upper glume ovate; 5 mm long; 1.2 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume apex acute.

FLORETS Fertile lemma ovate; elliptic in profile; 4 mm long; membranous; keeled; 5 -veined. Lemma midvein ciliolate. Lemma lateral veins prominent. Lemma surface scaberulous; puberulous; hairy on veins. Lemma margins ciliolate. Lemma apex acute. Palea keels ciliate; adorned above. Apical sterile florets resembling fertile though underdeveloped.
