Morphology General Habit
Perennial. Culms robust; 25-200 cm long. Leaf-sheaths keeled; glabrous on surface, or pubescent. Ligule a fringe of hairs; 2.5 mm long. Leaf-blades 16-41 cm long; 6-16 mm wide. Leaf-blade surface scabrous; glabrous, or puberulous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; loose (internodes 1.7-3.3mm); 7.8-28 cm long; 1.6-2.3 cm wide. Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis angular; pubescent; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1-2 in the cluster. Involucre composed of bristles; connate into a cup below; with 2-3 mm connate; ovate; 10-14 mm long; base obconical (2.5-4.5mm); base pubescent. Involucral bristles deciduous with the fertile spikelets; numerous; with an outer whorl of thinner bristles; 6-10 in principal whorl; inner bristles longer than outer; 5.7-7 mm long; terete; rigid; retrorsely scaberulous; ciliate; spinose.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acuminate; 6-7 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; 6-7 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; 1.3-3.5 mm long; 0.25-0.5 length of spikelet; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 4.5-6.3 mm long; 0.75-0.9 length of spikelet; membranous; without keels; 3-5 -veined. Upper glume apex setaceously attenuate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; with palea. Lemma of lower sterile floret ovate; 5.9-6.6 mm long; 0.9 length of spikelet; membranous; 5 -veined; acute. Fertile lemma ovate; 5.8-7 mm long; coriaceous; much thinner on margins; without keel; 3 -veined. Lemma margins flat. Lemma apex obtuse. Palea coriaceous.
