    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 3-4.5 mm long; falling entire.
    Glume
    Glumes one the lower absent or obscure; reaching apex of florets, or shorter than spikelet; thinner than fertile lemma. Upper glume elliptic; 0.5-1 length of spikelet; membranous; without keels. Upper glume apex acuminate; muticous, or awned; 1 -awned.

Lemma of lower sterile floret elliptic; 1 length of spikelet; membranous; 7 -veined; ribbed; convex across back, or flat across back; scabrous; rough on veins; acute; awned. Awn of lower sterile floret 1-3 mm long. Fertile lemma elliptic; 3-4.5 mm long; chartaceous; much thinner on margins; without keel. Lemma margins flat; covering most of palea. Lemma apex acute. Palea chartaceous.
