    Inflorescences

    Spikelets
    Spikelets comprising 6-14 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; (15-)30-50 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 6-14 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; (15-)30-50 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet. Lower glume lanceolate; 9-11 mm long; 1 length of upper glume; membranous; without keels; 3(-5) -veined. Lower glume surface glabrous, or hispidulous. Lower glume apex acuminate. Upper glume lanceolate, or ovate; 9-13 mm long; 0.75 length of adjacent fertile lemma; membranous; without keels; 5-7 -veined. Upper glume surface glabrous, or hispidulous. Upper glume apex acuminate.
    Florets
    Fertile lemma elliptic; 12-18 mm long; herbaceous; much thinner on margins; purple; without keel; 7 -veined. Lemma surface glabrous, or hispidulous. Lemma apex dentate; 2 -fid; with lobes 1.2-2.5 mm long; awned; 1 -awned. Principal lemma awn subapical; reflexed and briefly coiled at base of limb; flat below; 15-30 mm long overall. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3; 1.5-2 mm long. Ovary with a fleshy appendage above style insertion; pubescent on apex.
