INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 1.5–4 cm long. Primary panicle branches moderately divided.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets orbicular; dorsally compressed; 1.5 mm long; falling entire.

Upper glume ovate; 0.8–0.9 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface puberulous. Upper glume apex acute.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 5 -veined; puberulous; acute. Fertile lemma elliptic; dorsally compressed; 1.5 mm long; indurate; pallid; shiny; without keel. Lemma surface scaberulous; rough above. Lemma margins involute. Palea involute; indurate.
