Uniola L.

Spikelets laterally compressed, few-to several-flowered, the rachilla disarticu-lating above the glumes and between the florets (tardily or not at all disarticulating in our species), with 1-4 empty lemmas below the fertile florets; glumes narrow, compressed-keeled, acute or acuminate, the first 1-to 5-nerved, the second 3-to 5-nerved; lemmas compressed-keeled, 5-to several-nerved, the nerves often ob-scure, acute or acuminate, awnless or sometimes mucronate; palea shorter than the lemma, the keels straight (in our species) or prominently bowed.
