Morphology General Habit
Perennial; caespitose. Culms erect; robust; 200-300 cm long; 3-6 mm diam.; swollen at the base. Culm-internodes thin-walled; distally glabrous. Culm-nodes pubescent. Lateral branches ample. Leaf-sheaths without keel; glabrous on surface. Ligule a ciliate membrane; 1.5-3.5 mm long. Leaf-blades lanceolate; 17-45 cm long; 13-35 mm wide. Leaf-blade surface glabrous, or hirsute; hairy on both sides.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; terminal and axillary; subtended by an inflated leaf-sheath. Panicle spiciform; linear; flexuous; 3-10 cm long; 0.7-1 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis scabrous; glabrous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Involucre composed of bristles; 3-5 mm long; base truncate. Involucral bristles deciduous with the fertile spikelets; numerous; in one whorl; 30 in principal whorl; with one conspicuously longer bristle; 15-20 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 ovate; dorsally compressed; acute, or acuminate; 4.8-6.2 mm long; falling entire; deciduous with accessory branch structures.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acute, or acuminate; 4.8-6.2 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.5-1.2 mm long; 0.1-0.2 length of spikelet; membranous; without keels; 0-1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume ovate; 1.8-2.5 mm long; 0.5 length of spikelet; membranous; without keels; 3 -veined. Upper glume lateral veins obscure. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret ovate; 3.8-5.4 mm long; 0.9-1 length of spikelet; membranous; 5 -veined; acute. Fertile lemma ovate; 3.8-5.4 mm long; chartaceous; without keel. Lemma margins flat. Palea 1 length of lemma; membranous.
