Perennial; caespitose. Rhizomes elongated. Culms erect; 12-85 cm long; 2-3 -noded. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 1.3-5 mm long; obtuse. Leaf-blades flat, or convolute; 2-21 cm long; 1-4 mm wide; glaucous. Leaf-blade surface scabrous. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; tapering above; 1.4-20 cm long; 0.6-1.2 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 3-3.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
