It is endemic to the Northwestern United States.
Lomatium farinosum is a small flowering perennial that flowers in early spring. It grows from a single taproot with a proportionally large nearly spherical tuber several inches deep. The glabrous leaves are dissected into small linear leaflets. The flowers are yellow or white and the stem is glabrous.[1]
