Morphology General Habit
Perennial; culms solitary. Rhizomes elongated. Culms erect, or decumbent; 35-65 cm long; 1.5-2.2 mm diam.; (2-)3-5 -noded. Culm-internodes smooth; distally glabrous. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 2.5-4.5 mm long; erose. Leaf-blades 3-7(-10.5) cm long; 1.4-5 mm wide. Leaf-blade surface scabrous; rough on both sides; glabrous. Leaf-blade margins scaberulous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle contracted; linear; interrupted; 3-7(-10.5) cm long; 0.5-1.4 cm wide. Primary panicle branches 1-5(-8) in number; 0.7-2.7 cm long. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 0.5-3.5 mm long; scabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 3-3.6 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 3-3.6 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume

Lower glume oblong, or ovate; 3 mm long; 1 length of upper glume; membranous; dark green, or purple; without keels, or 1-keeled; 3 -veined. Lower glume surface asperulous. Upper glume oblong, or ovate; 3 mm long; 1 length of adjacent fertile lemma; membranous; dark green, or purple; without keels, or 1-keeled; 3 -veined. Upper glume surface asperulous.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; dorsally compressed; 3 mm long; indurate; shiny; without keel; 5 -veined. Lemma apex obtuse. Palea 1 length of lemma; indurate; 2 -veined; without keels. Palea apex acute.
