|discussion=<p><i>Vulpia octoflora</i>, a widespread native species, tends to be displaced by the introduced <i>Bromus tectorum</i> in the Pacific Northwest. It grows in grasslands, sagebrush, and open woodlands, as well as in disturbed habitats and areas of secondary succession, such as old fields, roadsides, and ditches. Three varieties are recognized here, but their characterization is not completely satisfactory, e.g., plants of the southwestern United States with spikelets in the size range of <i></i></i>var.<i><i> glauca</i> often have densely pubescent lemmas, the distinguishing characteristic of var. birtella.</p>
