Range Extent20,000-200,000 square km (about 8000-80,000 square miles)
Number of Occurrences6 - 20
Rank Reasons
Endemic to a relatively small geographic area in Washington State and mostly restricted to serpentine substrates. Potentially threatened by road construction, mining, and ski area development.
Range Extent Comments
Wenatchee Mountains, Washington, with unconfirmed or historical outliers north by Mt. Baker and south by Mt. Rainier.
Occurrences Comments
12 sites known (Washington Heritage Program 1981); 1 reported from Oregon.
Threat Impact Comments
Isolated high elevation habitat that is not likely effected by human activities other than climatic change (Arnett, pers. comm. 2012)
Ecology & Habitat

Habitat

From the ponderosa pine belt upwards, often on serpentine (Hitchcock and Cronquist 1973). Open or sparsely wooded slopes and cliffs, often on talus, especially serpentine (Hitchcock et al. 1959). Restricted to serpentine and peridotite (Washington Heritage Program 1981).
