Leaf-blades 15-40 cm long; 4-9 mm wide. Leaf-blade midrib prominent beneath. Leaf-blade surface scaberulous; glabrous, or pilose; hairy adaxially. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; oblong; effuse; nodding; 18-25 cm long. Primary panicle branches drooping; 2 -nate; simple; 10-15 cm long; bearing 2-5 fertile spikelets on each lower branch. Panicle branches capillary; flexuous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels clavate; 2-5 mm long.
Morphology Reproductive morphology Inflorescences Spikelets

Fertile
Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 18-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-3 mm long; pubescent.
