    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 17-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1.2-1.7 mm long; pubescent; pungent. Floret callus hairs 0.5-1 mm long.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 17-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1.2-1.7 mm long; pubescent; pungent. Floret callus hairs 0.5-1 mm long.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 17-30 mm long; 1.3-1.5 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface glabrous, or pubescent. Lower glume apex emarginate, or obtuse; awned; 1 -awned. Lower glume awn 2-4 mm long. Upper glume lanceolate; 13-20 mm long; 2 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface glabrous, or pubescent. Upper glume apex emarginate, or obtuse; awned; 1 -awned. Upper glume awn 1-2 mm long.
    Florets
    Fertile lemma lanceolate; subterete; 7-8 mm long; coriaceous; pallid and light brown; mottled with last colour; without keel; 3 -veined. Lemma surface tuberculate; rough above. Lemma margins convolute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn 3-branched; with 32-76 mm long limb; with twisted column; deciduous; abscissing from top of lemma. Column of lemma awn 15-35 mm long. Lateral lemma awns 26-70 mm long; subequal to principal. Palea 0.2 length of lemma; without keels.
