    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume elliptic (1), or ovate (1); 0.75-0.875-1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute; muticous (1), or mucronate (1). Upper glume elliptic (1), or ovate (1); 0.75-1.125-1.5 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume apex acuminate (1), or setaceously attenuate (1).
