Morphology General Habit
Perennial. Culms erect, or geniculately ascending; robust; 60-120 cm long. Culm-internodes elliptical in section. Lateral branches sparse. Leaf-sheaths keeled; glabrous on surface; outer margin hairy. Leaf-sheath oral hairs lacking, or ciliate. Ligule a fringe of hairs; 2-4 mm long. Collar glabrous. Leaf-blades 15-20 cm long; 7-15 mm wide. Leaf-blade surface scabrous; rough on both sides.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle antrorsely scabrous above. Panicle spiciform; linear; interrupted; loose; truncate or rounded at the ends; 10-30 cm long; 1-2 cm wide. Primary panicle branches sterile at the tips. Panicle axis angular; scabrous; puberulous. Spikelets subtended by an involucre. Fertile spikelets pedicelled; 1 in the cluster. Involucre composed of bristles; 10-20 mm long. Involucral bristles persistent; 1 per spikelet; flexible; antrorsely scaberulous; glabrous. Pedicels oblong.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; gibbous; 2-2.3 mm long; falling entire.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; gibbous; 2-2.3 mm long; falling entire.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.33-0.5 length of spikelet; membranous; without keels; 3-5 -veined. Lower glume apex acute. Upper glume ovate; 0.66-0.75 length of spikelet; membranous; without keels; 5-7 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; with palea. Lemma of lower sterile floret ovate; 1 length of spikelet; membranous; 5 -veined; acute. Palea of lower sterile floret 1 length of lemma. Fertile lemma ovate; dorsally compressed; gibbous; 2-2.3 mm long; indurate; without keel. Lemma surface rugose. Lemma margins involute. Palea involute; indurate.
