Descriptions

Morphology General Habit
Perennial. Rhizomes elongated. Culms erect, or geniculately ascending; 25-40 cm long; 2-4 -noded. Leaf-sheaths smooth, or scaberulous; glabrous on surface, or pubescent. Ligule an eciliate membrane; 3 mm long; truncate. Leaf-blades 4-18 cm long; 2-4 mm wide. Leaf-blade surface hispid; hairy abaxially. Leaf-blade apex obtuse; callose.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle retrorsely scabrous above. Panicle spiciform; oblong; 1.5-3 cm long; 0.6-0.8 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis. Panicle axis pubescent. Spikelets spreading; solitary. Fertile spikelets pedicelled. Pedicels oblong; pubescent.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 3.5-4 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
Fertile
Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 3.5-4 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.
