INFLORESCENCE Inflorescence a panicle.

Panicle open; lanceolate; loose; bearing few spikelets. Panicle branches scaberulous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–7 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 5–7 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 0.5–1.2 mm long; 0.5 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume lanceolate; 1.3–2 mm long; 0.66 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex obtuse.

FLORETS Fertile lemma ovate; 2–2.5 mm long; membranous; without keel. Lemma surface scabrous; rough on veins. Lemma apex obtuse. Palea bowed outwards; 1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
