Abstract
Utah sweetvetch has a broad distribution from ranging from Alaska, across most of Canada, and south through the western United States to Nevada, Arizona, New Mexico, and Texas. It is particularly common in the Rocky Mountains and other mountainous regions of the western United States (Hitchcock and Cronquist 2018; Ross 2020). Subspecies mackenzii occupies only the northern range of the species, occurring from Alaska across Canada and south to Washington and Oregon (Hitchcock and Cronquist 2018). Subspecies boreale occurs from British Columbia to Manitoba and south, mainly in the Rocky Mountain states, but also in northeastern Oregon, the Dakotas, Nevada,
