Morphology General Habit
Perennial. Cataphylls evident. Culms 30-80 cm long. Leaf-sheaths longer than adjacent culm internode; smooth, or scaberulous. Ligule a ciliolate membrane; 1-4 mm long; obtuse. Leaf-blades filiform; convolute; 7-35 cm long; 1-2 mm wide; stiff. Leaf-blade surface puberulous; hairy adaxially. Leaf-blade apex pungent.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle antrorsely scabrous above. Panicle spiciform; linear; continuous; 6-10 cm long. Panicle axis scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous; pubescent; hairy at tip.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 6-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 6-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet, or reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 5.5-6.5 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume primary vein scabrous. Lower glume apex acute. Upper glume ovate; 5.5-6.5 mm long; membranous; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets similar; male; with palea; attached to and deciduous with the fertile. Lemma of lower sterile floret elliptic; 5-6.5 mm long; chartaceous; 1-keeled; 5 -veined; ciliolate on margins; obtuse; mucronate. Lemma of upper sterile floret oblong; 1 length of lower sterile floret; chartaceous; ciliolate on margins; obtuse; awned. Awn of upper sterile floret dorsal; arising 0.75 way up back of lemma; geniculate; 1.5-4 mm long. Fertile florets female. Fertile lemma ovate; 4-4.5 mm long; cartilaginous; without keel; 5 -veined. Lemma surface scaberulous; rough above. Lemma margins convolute; covering most of palea. Lemma apex acute. Palea linear; 1 -veined; without keels.
