Ligule an eciliate membrane; 0.5-1 mm long. Leaf-blades 10-20 cm long; 5 mm wide. Leaf-blade surface puberulous; hairy adaxially.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; oblong, or ovate; bilateral; 2-8 cm long; 10-20 mm wide. Rhachis pubescent on surface. Spikelet packing broadside to rhachis; crowded. Rhachis internodes oblong. Spikelets pectinate; solitary. Fertile spikelets sessile.
    Spikelets

    Fertile
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 10-15 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet; firmer than fertile lemma. Lower glume lanceolate; 4-6 mm long; 1 length of upper glume; coriaceous; much thinner on margins; 1-keeled; keeled all along; 1 -veined. Lower glume primary vein eciliate, or ciliate. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 1 mm long. Upper glume lanceolate; 4-6 mm long; 0.75-1 length of adjacent fertile lemma; coriaceous; with scarious margins; 1-keeled; keeled all along; 1 -veined. Upper glume primary vein eciliate, or ciliate. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 1 mm long.
    Florets
    Fertile lemma lanceolate; 6-8 mm long; chartaceous; glaucous; keeled; 5 -veined. Lemma surface pilose to villous. Lemma apex acute; awned; 1 -awned. Principal lemma awn 2 mm long overall. Palea 1 length of lemma. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 5-5.5 mm long. Ovary with a fleshy appendage below style insertion; pubescent on apex.
    Fruits
