Morphology General Habit
Perennial; caespitose. Culms erect; 39-100 cm long. Culm-internodes glaucous; distally glabrous. Culm-nodes constricted; brown; glabrous. Lateral branches lacking. Leaf-sheaths wider than blade at the collar; keeled; glabrous on surface; outer margin glabrous. Ligule a ciliate membrane; 1-1.5 mm long. Leaf-blades flat, or conduplicate; 8-22 cm long; 4.5-7.5 mm wide; glaucous. Leaf-blade surface glabrous. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; 7-10 cm long; 2-2.5 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs; pubescent; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Involucre composed of bristles; 10-14 mm long; base truncate; base 0.2-0.3 mm long. Involucral bristles deciduous with the fertile spikelets; numerous; with an outer whorl of thinner bristles; 20 in principal whorl; inner bristles shorter than outer; with one conspicuously longer bristle; 12-17 mm long; terete; flexible; glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acuminate; 5-6 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; acuminate; 5-6 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume

Lower glume apex obtuse, or acute. Upper glume ovate; 5-5.5 mm long; 0.9 length of spikelet; membranous; without keels; 7 -veined. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret ovate; 5.7-5.9 mm long; 1 length of spikelet; membranous; 5 -veined; acuminate. Fertile lemma ovate; 5.2-5.7 mm long; chartaceous; without keel; 5 -veined. Lemma margins flat. Lemma apex acuminate. Palea 1 length of lemma; membranous.
