Leaf-sheaths retrorsely scabrous; glabrous on surface, or pubescent. Ligule an eciliate membrane; lacerate. Leaf-blades 10-50 cm long; 1-8 mm wide. Leaf-blade surface pilose; sparsely hairy; hairy adaxially.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; oblong; 20-25 cm long. Panicle branches flexuous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 6-8 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 16-25 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
