    Leaves
    Leaf-blades 16–60 cm. long, 3–10 mm. wide, gradually tapering to a flexuous tip.
    Inflorescences

    Habit
    Perennial. Cataphylls evident. Rhizomes short; scaly. Culms 60-120 cm long. Lateral branches ample. Ligule an eciliate membrane. Leaf-blades 16-60 cm long; 3-10 mm wide. Leaf-blade apex attenuate; filiform.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; smoothly terete; unilateral; 5-12 cm long. Rhachis fragile at the nodes; semiterete. Rhachis internodes cuneate. Rhachis internode tip transverse; crateriform. Spikelets sunken; in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels fused to internode; united wholly; oblong; flattened; tip rectangular.
    Spikelets

Companion sterile spikelet glumes coriaceous; winged on keels; obtuse. Companion sterile spikelet lemmas 2; enclosed by glumes. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 2.5-4 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base truncate; with central peg; attached transversely.
    Sterile
