Bouteloua includes both annual and perennial grasses, which frequently form stolons.[9] Species have an inflorescence of 1 to 80 racemes or spikes positioned alternately on the culm (stem). The rachis (stem) of the spike is flattened. The spikelets are positioned along one side of the spike. Each spikelet contains one fertile floret, and usually one sterile floret.[10]
Distribution
Bouteloua is found only the Americas, with most diversity centered in the southwestern United States.[9] It also occurs in the Ciénaga de Zapata Biosphere Reserve of Cuba.[11]

Many species are important livestock forage, especially blue grama.[9]
