Leaves mostly basal. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs woolly. Ligule a fringe of hairs. Leaf-blades convolute; 40 cm long; 1.5 mm wide; stiff; eglandular. Leaf-blade surface glabrous. Leaf-blade margins smooth. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle; comprising 100 fertile spikelets. Panicle contracted; oblong; 5-15 cm long; 2-3.5 cm wide. Panicle branches eglandular; pubescent in axils, or bearded in axils. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 1 length of fertile spikelet; eglandular; smooth, or scaberulous; glabrous, or puberulous.
