Lower glume lateral veins absent (1), or distinct (2). Lower glume surface villous. Lower glume apex awned. Upper glume linear; 0.3-0.35-0.4 length of adjacent fertile lemma; coriaceous; with hyaline margins; without keels; 1 -veined (1), or 3 -veined (2). Upper glume surface villous. Upper glume apex acute (2), or acuminate (1); awned; 1 -awned.
    Florets
