Lower glume surface scabrous; rough on veins. Lower glume apex acute. Upper glume lanceolate; 6-8.5 mm long; 0.66-0.8 length of adjacent fertile lemma; coriaceous; with hyaline margins; without keels; 3-5 -veined. Upper glume surface scabrous; rough on veins. Upper glume hairs 2 mm long. Upper glume apex acute.
    Florets
