Spikelets lanceolate, or oblong; laterally compressed; 16-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-3 mm long; eventually visible between lemmas. Floret callus elongated; 2-3 mm long; pubescent; pungent; disarticulating obliquely.
    Fertile
    Spikelets comprising 2-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 16-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-3 mm long; eventually visible between lemmas. Floret callus elongated; 2-3 mm long; pubescent; pungent; disarticulating obliquely.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume linear; 6-10 mm long; 0.6-0.8 length of upper glume; membranous; without keels; 3 -veined. Lower glume apex acute. Upper glume linear; 10-13 mm long; 0.8-1 length of adjacent fertile lemma; membranous; without keels; 5 -veined. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; 10-17 mm long; chartaceous; without keel; 7 -veined. Lemma apex entire, or dentate; 2 -fid; awned; 1 -awned. Principal lemma awn dorsal; arising 0.7-0.8 way up back of lemma; coiled; 20-43 mm long overall. Apical sterile florets 1-2 in number; abscissing from fertile floret; in a clump; linear; 2-4 mm long. Apical sterile lemmas awned; 1 -awned.
    Flowers
    Lodicules 2; free; cuneate; fleshy; truncate. Anthers 3; 2.5-3 mm long. Stigmas 2. Ovary glabrous.
    Fruits
    Caryopsis with adherent pericarp. Embryo 0.1 length of caryopsis. Hilum punctiform.
