INFLORESCENCE Inflorescence a panicle.
Panicle contracted, or glomerate; linear; 1.5–3 cm long; 0.4–0.5 cm wide.
Spikelets solitary. Fertile spikelets sessile.
FERTILE SPIKELETS Spikelets comprising 10–14 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 6–10 mm long; breaking up at maturity; rhachilla persistent; retaining paleas. Rhachilla internodes 0.25 mm long; eventually visible between lemmas.

Lower glume apex acute. Upper glume lanceolate; 1.8 mm long; 0.9 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute.
FLORETS Fertile lemma ovate; 2 mm long; cartilaginous; keeled; 3 -veined. Lemma lateral veins obscure. Lemma apex acute. Palea 1.8 mm long. Apical sterile florets resembling fertile though underdeveloped.
