Notes: FNA24: "FNA24: "Vulpia microstachys is native to western North America, growing from British Columbia south through the western United States into Baja California. Four varieties are recognized here on the basis of spikelet indumentum, but they frequently occur together, and intergrading forms are known. No difference in their geographic or ecological distribution is known."

In light of the lack of distinction among varieties, we are recognizing only the species level taxon."
