INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 10–16 cm long; 3–6 cm wide. Primary panicle branches distant. Panicle branches sinuous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels flexuous; 2–12 mm long.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; obtuse; 1.5–1.7 mm long; falling entire.

GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.6–0.7 mm long; 0.5–0.6 length of spikelet; membranous; without keels. Upper glume ovate; 1 length of spikelet; membranous; 1-keeled. Upper glume apex acute.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous. Fertile lemma ovate; dorsally compressed; 1.2–1.4 mm long; indurate; pallid; shiny; without keel. Lemma margins involute. Palea involute; indurate.
