Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate. Primary panicle branches 2-7 -nate; bearing 1-5 fertile spikelets on each lower branch. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-9 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 12-22 mm long; breaking up at maturity; disarticulating below each fertile floret.
