INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; effuse; 5–20 cm long.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels tip widened.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3–4 mm long; breaking up at maturity; disarticulating below each fertile floret.
