INFLORESCENCE Inflorescence a panicle.
Panicle contracted; linear, or lanceolate; 15–40 cm long; 3–5 cm wide. Primary panicle branches 2–5 cm long.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3 mm long; breaking up at maturity; disarticulating below each fertile floret.
