    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 5-9 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1 mm long; pubescent; acute.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 5-9 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1 mm long; pubescent; acute.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 5-9 mm long; 1 length of upper glume; membranous; 1-keeled; 1-3 -veined. Lower glume lateral veins absent, or distinct. Lower glume surface smooth to scabrous. Lower glume apex acute, or acuminate; muticous, or mucronate. Upper glume lanceolate; 5-9 mm long; 1.2-1.3 length of adjacent fertile lemma; membranous; 1-keeled; 1-3 -veined. Upper glume lateral veins absent, or distinct. Upper glume surface smooth to scabrous. Upper glume apex emarginate, or obtuse; muticous, or mucronate.
    Florets
    Fertile lemma lanceolate; subterete; 4-7 mm long; coriaceous; pallid, or light brown, or purple; without keel; 3 -veined. Lemma margins involute; covering most of palea; without distinctive roughness, or scabrous. Lemma apex acute; awned; 3 -awned. Principal lemma awn flat below; with 12-24 mm long limb; without a column; persistent. Lateral lemma awns 10-21 mm long; subequal to principal. Palea 0.2 length of lemma; without keels.
