    Glume
    Glumes persistent; similar; reaching apex of florets, or exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 7-13 mm long; 0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface asperulous, or scabrous. Lower glume apex acute, or acuminate; muticous, or awned; 1 -awned. Lower glume awn 0.4 mm long. Upper glume lanceolate; 8-17 mm long; 1-1.5 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface asperulous, or scabrous. Upper glume apex acute, or acuminate; muticous, or awned; 1 -awned. Upper glume awn 0-4 mm long.
    Florets
    Fertile lemma lanceolate; subterete; 8-11 mm long; coriaceous; pallid and light brown; mottled with last colour; without keel; 3 -veined. Lemma surface smooth, or tuberculate; rough above. Lemma margins convolute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn 3-branched; with 17-50 mm long limb; with a straight or slightly twisted column, or with twisted column; persistent. Column of lemma awn 1-9 mm long. Lateral lemma awns 15-45 mm long; shorter than principal. Palea 0.2 length of lemma; without keels.
