    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; (2-)2.5-4.5 mm long; 0.5-0.75 length of upper glume; chartaceous; purple; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface scabrous. Lower glume apex acute. Upper glume lanceolate; 4-6 mm long; 0.6-0.7 length of adjacent fertile lemma; chartaceous; purple; without keels; 3 -veined. Upper glume lateral veins obscure. Upper glume surface scabrous. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; 7-8.5 mm long; membranous, or chartaceous; purple; without keel; 3-5 -veined. Lemma surface scabrous; rough above. Lemma apex acute; awned; 1 -awned. Principal lemma awn 3-4(-5) mm long overall. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.
