Leaf-sheaths glabrous on surface, or pubescent. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 0.2 mm long. Leaf-blades 15-25 cm long; 3-8 mm wide. Leaf-blade surface glabrous, or puberulous; hairy adaxially.
    Inflorescences

    Spikelets
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 15-20 mm long; 5-7 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5-2 mm long; pubescent.
    Fertile
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 15-20 mm long; 5-7 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5-2 mm long; pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 7-9 mm long; 0.8 length of upper glume; coriaceous; without keels; 9 -veined. Lower glume surface scabrous; rough on veins. Lower glume apex acute. Upper glume lanceolate; 8-11 mm long; coriaceous; without keels; 9 -veined. Upper glume surface scabrous; rough on veins. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; 9-12 mm long; coriaceous; 5 -veined. Lemma surface scabrous; glabrous, or pilose. Lemma apex acute; awned; 1 -awned. Principal lemma awn curved; 25-40 mm long overall. Palea 1 length of lemma. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.

    Fruits
    Caryopsis with adherent pericarp.
