INFLORESCENCE Inflorescence a panicle.

Panicle open; pyramidal; loose, or effuse; 10–25 cm long. Primary panicle branches spreading; 5–7 -nate. Panicle branches scaberulous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 5–6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 7–8 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; dissimilar; shorter than spikelet. Lower glume ovate; 0.8–1 mm long; 0.66 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse, or acute. Upper glume ovate; 1.5–1.7 mm long; 0.75 length of adjacent fertile lemma; membranous; without keels.

FLORETS Fertile lemma oblong, or obovate; 2.3–2.7 mm long; membranous; much thinner above; without keel; 5 -veined. Lemma surface pubescent; hairy at base. Lemma apex truncate. Palea 2 -veined. Palea keels scabrous; ciliate; adorned below; with 0.33 of their length adorned. Apical sterile florets resembling fertile though underdeveloped.
