Leaf-sheaths open for most of their length; with 1 of their length closed; smooth, or scaberulous; glabrous on surface. Ligule a ciliolate membrane; 0.5 mm long. Leaf-blades filiform; convolute; 25-50 cm long; 0.5-0.8 mm wide. Leaf-blade venation comprising 10-12 vascular bundles; with subepidermal sclerenchyma attached to veins above and below; without layer of subepidermal sclerenchyma masking vein striation. Leaf-blade surface puberulous; hairy adaxially. Leaf-blade apex filiform.
    Inflorescences
    Inflorescence a panicle. Panicle open; linear, or oblong; dense; 10-18 cm long. Primary panicle branches 2 -nate. Panicle axis scabrous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 8.5-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.8-1.5 mm long; smooth.
    Fertile
    Spikelets comprising 5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 8.5-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.8-1.5 mm long; smooth.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 3.5-4.5 mm long; 0.75 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 5-5.5 mm long; 0.7-0.8 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; 6-7 mm long; chartaceous; without keel; 5 -veined. Lemma midvein without distinctive roughness. Lemma surface scaberulous; rough above. Lemma apex acute; muticous, or mucronate. Palea 2 -veined. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
