Morphology General Habit
Perennial. Culms rambling; 100-700 cm long; wiry. Culm-internodes distally glabrous. Lateral branches ample. Ligule a fringe of hairs. Leaf-blades deciduous at the ligule; involute; 0.5-4 cm long; 1-2 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; loose; 2-5 cm long. Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis glabrous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Involucre composed of bristles; 4-10 mm long; base truncate; base 0.75 mm long; base pubescent. Involucral bristles deciduous with the fertile spikelets; few; with longest bristle scarcely emergent; 15-20 mm long; terete; flexible; glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4.2-4.5 mm long; falling entire; deciduous with accessory branch structures.
