Leaf-blades oblong; 20-28 cm long; 35-60 mm wide. Leaf-blade surface pubescent; hairy abaxially. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; obovate; 12 cm long. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-8 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 25-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3-4 mm long; pubescent.
Fertile
Spikelets comprising 5-8 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 25-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3-4 mm long; pubescent.
Morphology Reproductive morphology Inflorescences Bracts Glume
