Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 0.5 mm long; truncate. Leaf-blades 21-23 cm long; 3-3.5 mm wide; flaccid. Leaf-blade surface scabrous; rough adaxially; glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle glabrous. Panicle open; nodding; 13-16 cm long; 2.5-3 cm wide. Primary panicle branches 3 -nate; 7 cm long; bearing 3 fertile spikelets on each lower branch. Panicle axis scabrous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets laterally compressed; 18-23 mm long; 5-8 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-2.5 mm long; pubescent. Floret callus pilose; hairy in a ring above; disarticulating obliquely; with circular scar.
