    Fertile
    Spikelets comprising 6-12 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pilose.

Upper glume apex acute, or acuminate.
    Florets
    Fertile lemma ovate; 3 mm long; membranous; without keel; 3 -veined. Lemma lateral veins extending close to apex. Lemma apex dentate; 2 -fid; mucronate, or awned; 1 -awned. Principal lemma awn from a sinus; 0.2-0.5 mm long overall. Palea 1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
