INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 3–9 cm long; 0.5–1.5 cm wide. Primary panicle branches appressed.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 5–25 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 3–12 mm long; 2 mm wide; breaking up at maturity; rhachilla persistent; shedding paleas. Rhachilla internodes eventually visible between lemmas.

GLUMES Glumes deciduous; similar; shorter than spikelet. Lower glume ovate; 1 mm long; 0.6 length of upper glume; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume lanceolate; 1.5 mm long; 1 length of adjacent fertile lemma; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex obtuse.

FLORETS Fertile lemma elliptic, or oblong; 1.4–1.7 mm long; membranous; grey; keeled; 3 -veined. Lemma apex obtuse. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
