Perennial; caespitose. Rhizomes short. Culms erect; 30-120 cm long. Lateral branches fastigiate. Leaf-sheaths without keel. Ligule a fringe of hairs. Leaf-blades flat; 5-40 cm long; 4-13 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; 4-22 cm long. Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis angular; scaberulous; glabrous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 2-3 in the cluster. Involucre composed of bristles; 12-22 mm long; base obtuse; base 0.3-0.7 mm long. Involucral bristles deciduous with the fertile spikelets; numerous; 12-22 mm long; terete; flexible; glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Companion sterile spikelets well-developed; male; lanceolate; 4.5-6.5 mm long; as long as fertile (and similar to it); deciduous with the fertile. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4.5-6.5 mm long; falling entire; deciduous with accessory branch structures.
Sterile
Companion sterile spikelets well-developed; male; lanceolate; 4.5-6.5 mm long; as long as fertile (and similar to it); deciduous with the fertile.
Fertile

Lower glume apex emarginate, or obtuse, or acute. Upper glume oblong; 0.33-0.66 length of spikelet; membranous; without keels. Upper glume apex acute, or acuminate.
Morphology Reproductive morphology Flowers Florets
