Morphology General Habit
Perennial. Culms 70-100 cm long. Culm-nodes pubescent. Lateral branches ample. Ligule a fringe of hairs. Leaf-blades 12-25 cm long; 6-15 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; terminal and axillary. Panicle spiciform; linear; 5-7 cm long. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis angular; scabrous; glabrous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Involucre composed of bristles; 5-6 mm long; base truncate. Involucral bristles deciduous with the fertile spikelets; numerous; 15-20 in principal whorl; with one conspicuously longer bristle; 10-12 mm long; terete; flexible; smooth; glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5.5-6.2 mm long; falling entire; deciduous with accessory branch structures.
