INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic; effuse; 2–16 cm long; 2–7 cm wide. Primary panicle branches ascending; 1.5–10 cm long. Panicle branches capillary.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels cuneate; 0.8–8 mm long; glabrous.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 1.5–2.3 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; reaching apex of florets. Lower glume ovate; 1.5–2.3 mm long; 1 length of upper glume; membranous; much thinner on margins; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 1.5–2.3 mm long; 1 length of adjacent fertile lemma; membranous; with hyaline margins; without keels; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma elliptic; 1.5–2.3 mm long; membranous; without keel; 3 -veined. Lemma apex obtuse. Palea 2 -veined.
