Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; continuous, or interrupted; 2-10 cm long. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
