Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; lanceolate; 6-18 cm long; 5-23 mm wide; herbaceous. Leaf-blade venation with distinct cross veins. Leaf-blade surface pubescent; hairy adaxially. Leaf-blade margins scabrous.
    Inflorescences

    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 6-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 6-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface pubescent. Lower glume apex acute; muticous, or mucronate. Upper glume lanceolate; 0.33-0.5 length of adjacent fertile lemma; 1-keeled; 3 -veined. Upper glume surface pubescent. Upper glume apex acute; muticous, or mucronate.
    Florets
    Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 0.5-0.66 length of fertile lemma; chartaceous; 3-5 -veined; pubescent; hairy above; setaceously attenuate. Lemma of upper sterile floret ovate; 1.5-2 length of lower sterile floret; chartaceous; setaceously attenuate. Fertile lemma ovate; 6-7 mm long; coriaceous; without keel; 7 -veined. Lemma surface pubescent. Lemma apex acute. Palea 1 length of lemma; 4 -veined. Palea apex with excurrent keel veins.
