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

Publication: Blumea 2: 320.

Origin: Native

selected vouchers: Not at WTU; WS?

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. hirtella is most frequent from British Columbia south through the western United States and into Mexico. It is the most common variey of V. octoflora in the southwest.
