    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 5.5-13 mm long; 0.9-1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume primary vein scabrous. Lower glume surface smooth, or asperulous; glabrous, or pilose. Lower glume apex acute, or acuminate; awned; 1 -awned. Lower glume awn 1.5 mm long. Upper glume lanceolate; 6.5-13 mm long; 0.9-1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface glabrous, or pilose. Upper glume apex dentate; 2 -fid; acute, or acuminate; awned; 1 -awned. Upper glume awn 2.5 mm long.
    Florets
    Fertile lemma lanceolate; subterete; 7-12.5 mm long; coriaceous; without keel; 3 -veined. Lemma surface smooth, or scaberulous. Lemma margins involute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn geniculate, or 3-branched; with 6-20 mm long limb; with twisted column; persistent. Column of lemma awn 4-9 mm long. Lateral lemma awns 0-4 mm long; shorter than principal. Palea 0.2 length of lemma; without keels.
