    Glume
    Glumes persistent; similar; shorter than spikelet, or reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 9 mm long; 0.9 length of upper glume; scarious; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 1-2.5 mm long. Upper glume lanceolate; 10-11 mm long; 1-1.2 length of adjacent fertile lemma; scarious; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex dentate; 2 -fid; awned; 1 -awned. Upper glume awn 2.5 mm long.
    Florets
