Morphology General Habit
Perennial. Culms erect, or geniculately ascending; 80-180 cm long; 8-14 -noded. Leaf-sheaths longer than adjacent culm internode; glabrous on surface; outer margin glabrous, or hairy. Ligule a fringe of hairs; 2-3 mm long. Leaf-blades flat; 30-90 cm long; 5-20 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; 15-30 cm long; 2-3 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis retrorsely scabrous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1-3 in the cluster. Involucre composed of bristles; 15-40 mm long; base obtuse. Involucral bristles deciduous with the fertile spikelets; numerous; 15-40 mm long; terete; flexible; antrorsely scaberulous; glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 6-8 mm long; falling entire; deciduous with accessory branch structures.
