    Glume
    Glumes similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 12-14 mm long; 1.2-1.5 length of upper glume; membranous; 1 -veined. Lower glume lateral veins absent. Lower glume surface smooth, or scabrous. Lower glume apex setaceously attenuate. Upper glume lanceolate; 10 mm long; 1.2-1.3 length of adjacent fertile lemma; membranous; 1 -veined. Upper glume lateral veins absent. Upper glume surface smooth, or scabrous. Upper glume apex setaceously attenuate.
