Vulpia octoflora (Walter) Rydb. var. octoflora[FNA24, HC2]
six-weeks fescue

Publication: Bull. Torrey Bot. Club 36: 538. 1909.

Origin: Native

selected vouchers: WTU

Notes: FNA24: "Vulpia octoflora, a widespread native species, tends to be displaced by the introduced Bromus tectorum 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 var. glauca often have densely pubescent lemmas, the distinguishing characteristic of var. hirtella.

Vulpia octoflora var. octoflora is widespread throughout southern Canada, the United States, and Mexico, and has been introduced into temperate regions of South America, Europe, and Asia. It is most common from northern Oklahoma to Virginia, south to the Texas Gulf prairie and Florida."
