Rank Reasons
In North America it is mainly a western species with isolated populations in West Virginia; it is found in Europe and Asia also (FNAEC, 1993). Based on herbarium records, the species appears to have many sites in Europe.
Range Extent Comments
Southwestern South Dakota to Arizona and Texas and along the California Sierra Nevada to southwestern Oregon, with a disjunct population in West Virginia. Based on specimen records, this species appears to be common in Europe.
Occurrences Comments
40-50 EOs currently known (estimate by J. Shevock); may be about that many more again out there. 6 reported in CA.
Threat Impact Comments
Habitat is high montane and isolated. Reports of hybridization in Europe. Easily dislodged from rock crevices by hikers and rock climbers.
