Leaf-blades 10-25 cm long; 8-25 mm wide; flaccid. Leaf-blade surface glabrous, or puberulous. Leaf-blade margins scaberulous.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; scanty. Inflorescence a panicle; terminal and axillary. Panicle spiciform; linear; 1.5-3 cm long.

Fertile spikelets sessile; 1 in the cluster. Involucre composed of bristles; base obtuse. Involucral bristles deciduous with the fertile spikelets; in one whorl; 1 in principal whorl; 10-20 mm long; terete; flexible; glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; acute; 2-3 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base truncate.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; acute; 2-3 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base truncate.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet; thinner than fertile lemma. Lower glume oblong; 0.1-0.5 mm long; 1 length of upper glume; 0.05-0.15 length of spikelet; hyaline; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume oblong; 0.1-0.5 mm long; 0.05-0.15 length of spikelet; hyaline; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex emarginate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; 1 length of spikelet; membranous; 5 -veined; smooth, or scaberulous; acute. Fertile lemma elliptic; 2-3 mm long; cartilaginous; without keel; 5 -veined. Lemma surface smooth, or scaberulous. Lemma margins flat. Lemma apex acute. Palea cartilaginous.
