Spikelets 2- to 4-flowered, compressed, the rachilla disarticulating 
above the glumes and between the florets, prolonged beyond the 
perfect florets as a slender bristle or bearing a reduced or sterile 
floret at the tip; glumes usually about equal in length but unequal 
in shape, the lower narrow and sometimes shorter, 1-nerved, the upper 
somewhat broader above the middle, wider than the lower, 3- to 
5-nerved; lemmas somewhat scarious and shining, the lowermost a 
little longer than the glume, obscurely 5-nerved, acute or short- 
awned, the awn, if present, borne just below the apex. Slender
