Ligule a ciliolate membrane; 0.5-1 mm long. Leaf-blades filiform; conduplicate; 15-60 cm long; 1-1.2 mm wide. Leaf-blade venation comprising 14-16 vascular bundles; with 13-15 inner ridges; with subepidermal sclerenchyma attached to veins below; without layer of subepidermal sclerenchyma masking vein striation.

    Inflorescences
    Inflorescence a panicle. Panicle open; oblong; 10-20 cm long. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8-14 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.2-1.9 mm long; scaberulous.
    Fertile
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8-14 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.2-1.9 mm long; scaberulous.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 2.8-4.5 mm long; 0.6-0.7 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 4.5-6.5 mm long; 0.75 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume apex acute.
    Florets
