    Description

    Gray’s biscuitroot is one of the most widespread Lomatium species (Thompson 1987a). It is most common in the western US from eastern Washington and Oregon south to northeastern Nevada, western Wyoming, western Colorado, and northwestern New Mexico (Coulter and Rose 1900; Hermann 1966). Populations occur from near sea level to near alpine habitats. Populations on the Saltspring and Galiano islands of British Columbia represent disjunct populations that are the northernmost and coastalmost. Populations in California, like those in British Columbia, are rare and disjunct (COSEWIC 2008). Variety grayi occurs throughout the species range, and variety depauperatum occurs only in Nevada and Utah (Kartesz 2015).
