Abstract
Parsnipflower buckwheat is an Inland West species, occurring from British Columbia and northern and central Montana south to eastern California, northern Nevada and Utah, and the northwestern corner of Colorado (Reveal 2005; Welsh et al. 2016). Currently parsnipflower buckwheat occurs as fairly small populations along the northern fringe of the central Great Basin and is more dominant in the Columbia Basin, Snake River Plain, and the Basin and Range of southeast Oregon (J. Johnson, NV Natural Heritage Program, personal communication, August 2019). Variety heracleoides is the most widely distributed and occurs throughout the species range. Variety leucophaeum is restricted to eastern Washington and northern Idaho. It occurs as scattered populations in Adams, Chelan, Douglas, Kittitas, Lincoln, Okanogan, Spokane, Stevens, and Whitman counties in Washington and adjacent Gooding and Kootenai counties in Idaho (Reveal 2005).
