INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; effuse; 1.2–2 cm long; bearing few spikelets. Panicle branches scaberulous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 5–10 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 8–14 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 1.7–2.2 mm long; 0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 2.3–3 mm long; 0.75 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma lanceolate, or ovate; 3.2–3.5 mm long; membranous; without keel. Lemma surface scaberulous; rough on veins. Lemma apex acute. Palea bowed outwards; 1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
