Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; 10-15(-23) cm long; 1 cm wide. Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis with rounded ribs; puberulous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster.
