Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear, or oblong; 1.5-3.5 cm long; 0.5 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis. Panicle axis with rounded ribs. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 3-3.2 mm long; falling entire.
