INFLORESCENCE Inflorescence a panicle.
Panicle contracted; linear; 13 cm long.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 10 mm long; breaking up at maturity; disarticulating below each fertile floret.

Lemma of lower sterile floret lanceolate; 3 mm long; 0.4 length of fertile lemma; chartaceous. Lemma of upper sterile floret lanceolate; 6 mm long; chartaceous.
