Micranthes occidentalis (S. Watson) Small[FNA8, HC2]
mountain saxifrage, redwool saxifrage, western saxifrage
Publication: N. Amer. Fl. 22: 144. 1905.
Origin: Native
Herbarium search: CPNWH
Notes: FNA8: "Micranthes occidentalis appears closely related to the little-known M. mexicana (Engler & Irmscher) Brouillet & Gornall from Chihuahua, Mexico. The latter is the only species of the genus that occurs in Mexico and not in the United States. Micranthes occidentalis is disjunct between the northern Rocky Mountains and the Cypress Hills of southeastern Alberta and southwestern Saskatchewan, and the Black Hills of South Dakota. It hybridizes with M. idahoensis where their ranges overlap."
