Morphology General Habit
Perennial; caespitose. Basal innovations extravaginal. Culms erect, or geniculately ascending; 35-70 cm long; 3 -noded. Culm-nodes glabrous, or pubescent. Lateral branches lacking. Leaf-sheaths puberulous, or pubescent; with tubercle-based hairs. Ligule an eciliate membrane; 2.25-3.5 mm long. Leaf-blades 19-25.5 cm long; 2-6 mm wide; flaccid. Leaf-blade surface scabrous; rough on both sides; pubescent; hairy adaxially, or on both sides.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle pubescent above. Panicle open; nodding; 18-22 cm long; 2.5-4 cm wide. Primary panicle branches 2 -nate; 7-14 cm long; bearing 1-2(-4) fertile spikelets on each lower branch. Panicle axis scabrous. Panicle branches scaberulous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 6-7 fertile florets; with diminished florets at the apex. Spikelets laterally compressed; 17-30 mm long; 4 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.7-3.3 mm long; pubescent. Floret callus pilose; disarticulating obliquely; with circular scar.
Fertile

Spikelets laterally compressed; 17-30 mm long; 4 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.7-3.3 mm long; pubescent. Floret callus pilose; disarticulating obliquely; with circular scar.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume lanceolate; 7.5-9 mm long; 0.75 length of upper glume; membranous; 1-keeled; 3-5 -veined. Lower glume primary vein scaberulous. Lower glume apex acute. Upper glume lanceolate; 12.5-13 mm long; 0.75 length of adjacent fertile lemma; membranous; 1-keeled; 5(-7) -veined. Upper glume primary vein scaberulous. Upper glume apex acute; muticous, or mucronate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate; 12-13 mm long; chartaceous; without keel; (3-)5-7 -veined. Lemma surface scaberulous; rough on veins. Lemma margins pubescent. Lemma apex awned; 1 -awned. Principal lemma awn subapical; 5-10 mm long overall. Palea 8-11 mm long; 0.66-0.85 length of lemma. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
