Culm-sheaths deciduous; hispid; hairy on margins; auriculate; with obtuse auricles; with 4 mm high auricles; setose on shoulders; shoulders with 7 mm long hairs. Culm-sheath ligule 6 mm high; ciliate. Culm-sheath blade lanceolate; glabrous on surface. Leaves 2-5 per branch. Leaf-sheaths glabrous on surface, or pubescent. Leaf-sheath oral hairs ciliate; deciduous. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 4 mm long; erose. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 11-21 cm long; 3-6 mm wide; dark green and mid-green; discolorous with last colour beneath. Leaf-blade venation with 10-14 secondary veins. Leaf-blade surface glabrous. Leaf-blade apex attenuate.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes, or comprising only a few spikelets. Racemes 1; single; bearing few fertile spikelets; bearing 3-5 fertile spikelets on each. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 2-13 mm long; glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 3-10 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 25-70 mm long; 3-6 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 7 mm long; pubescent.
