Leaf-sheaths tubular for much of their length; with 1 of their length closed; smooth; glabrous on surface. Ligule an eciliate membrane; 4-5 mm long; truncate. Leaf-blades 25-30 cm long; 10-14 mm wide. Leaf-blade venation comprising 22-25 vascular bundles; with subepidermal sclerenchyma attached to veins above and below; without layer of subepidermal sclerenchyma masking vein striation. Leaf-blade surface scabrous. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; 30-35 cm long. Primary panicle branches 2-6 -nate; whorled at most nodes. Panicle axis smooth. Panicle branches flexuous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15-18 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-1.5 mm long; scaberulous.
    Fertile
    Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15-18 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-1.5 mm long; scaberulous.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 5.5-6.5 mm long; 0.75 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 7.5-8 mm long; 0.7-0.8 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume primary vein scaberulous. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; 10-11 mm long; chartaceous; mid-green; without keel; 5 -veined. Lemma surface scabrous. Lemma apex acute; muticous. Palea 1 length of lemma; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 4 mm long. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; oblong; 5 mm long; hairy at apex. Hilum linear; 0.75 length of caryopsis.
