Ligule an eciliate membrane; 1 mm long. Leaf-blades 20-45 cm long; 2-5 mm wide. Leaf-blade surface smooth, or scaberulous; pilose; hairy on both sides.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Peduncle pubescent above. Racemes 1; single; bilateral; (3.5-)5-6.5 cm long; 10-15 mm wide. Rhachis fragile at the nodes; flattened; ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 1.5-1.75 mm long; falling with spikelet above. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 10-12 mm long; falling entire; deciduous with accessory branch structures.
Fertile
Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 10-12 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
