Leaf-blades 9-18 cm long; 3-5 mm wide. Leaf-blade surface hirsute; with tubercle-based hairs. Leaf-blade margins scaberulous.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; 5-10 cm long; bearing 15-30 fertile spikelets on each. Rhachis fragile at the nodes; subterete; ciliate on margins. Rhachis hairs on upper part of internode and on lower part of internode; 2-3 mm long. Rhachis internodes linear; 2.5 mm long. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear; without a translucent median line; ciliate; hairy above; with 2-3 mm long hairs.
    Spikelets
    Companion sterile spikelets well-developed; male; lanceolate; 6 mm long; shorter than fertile; separately deciduous. Companion sterile spikelet glumes 11 -veined. Companion sterile spikelet lemmas enclosed by glumes; muticous. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 7.5-8.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pubescent; base obtuse; attached transversely. Spikelet callus hairs 0.3 mm long.
    Sterile

Spikelets oblong; dorsally compressed; 7.5-8.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pubescent; base obtuse; attached transversely. Spikelet callus hairs 0.3 mm long.
    Glume
    Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; coriaceous; without keels; keel-less except near apex; winged on margins; winged above; 11 -veined. Lower glume surface convex. Lower glume apex dentate. Upper glume lanceolate; coriaceous; 1-keeled; 3 -veined. Upper glume primary vein grooved on either side. Upper glume apex acuminate.
