Lateral branches lacking. Leaves mostly basal. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs lacking, or ciliate. Ligule a fringe of hairs. Leaf-blades filiform; convolute; 6-20 cm long; 0.5-1.5 mm wide; stiff; eglandular. Leaf-blade margins smooth. Leaf-blade apex acute; muticous, or pungent.
    Inflorescences
    Inflorescence a panicle; comprising 50 fertile spikelets. Panicle contracted; linear, or lanceolate; 2.5-8 cm long; 1.5-6 cm wide. Panicle branches eglandular; glabrous in axils, or pubescent in axils, or bearded in axils. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; 0.8 length of fertile spikelet; eglandular; smooth, or scaberulous.
    Spikelets
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets cuneate; laterally compressed; 10-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Fertile
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets cuneate; laterally compressed; 10-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Glume
    Glumes persistent; similar; exceeding apex of florets; gaping. Lower glume elliptic; 10-12 mm long; 1 length of upper glume; membranous; yellow; 1-keeled; 1 -veined. Lower glume primary vein smooth, or scaberulous. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume elliptic; 10-12 mm long; 2 length of adjacent fertile lemma; membranous; yellow; 1-keeled; 1 -veined. Upper glume primary vein smooth, or scaberulous. Upper glume lateral veins absent.
