    Habit
    Perennial; caespitose. Culms erect; 60 cm long. Leaves cauline. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs scanty. Ligule an eciliate membrane. Leaf-blade base broadly rounded; with a brief petiole-like connection to sheath; petiole pubescent. Leaf-blades oblong; 8-12 cm long; 20-25 mm wide. Leaf-blade surface glabrous. Leaf-blade apex acuminate.
    Inflorescences
    Monoecious; with male and female spikelets in the same inflorescence. Synflorescence on a separate leafless culm. Inflorescence composed of racemes. Racemes 1; single; erect; multilateral; 3.5-4.5 cm long; 8-10 mm wide. Rhachis fragile at the nodes; terminating in a sterile spikelet. Rhachis internodes linear. Sexes mixed (in a cluster at each node). Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Male spikelets pedicelled; 5 in a cluster. Involucre composed of imperfect spikelets; with pedicels forming a cup; oblong. Pedicels fused to each other; united along margins; oblong; flattened; 3 mm long; pubescent and ciliate; hairy on surface and margins; tip rectangular.
    Spikelets

Spikelets ovate; laterally compressed; compressed slightly; 6 mm long; falling entire; deciduous with accessory branch structures. Male spikelets distinct from female; 1 flowered; deciduous with the fertile; ovate; 4 mm long; hairy. Male spikelet glumes 2; triangular; 2-3 mm long; awned (0.5mm). Male spikelet lemma 4 mm long; 3 -veined; with cross-veins.
    Fertile

Upper glume lanceolate; 6 mm long; 1.2 length of adjacent fertile lemma; chartaceous; 1-keeled. Upper glume apex acuminate.
    Florets
    Fertile florets female. Fertile lemma ovate; 5 mm long; coriaceous; without keel; 3 -veined. Lemma surface puberulous. Lemma apex obtuse. Palea coriaceous; without keels.
