Rank Reasons
There are 25 locations documented in 3 states. However, given that the full distribution includes at least five states in at least 24 counties, the total number of locations is expected to be much higher.
Range Extent Comments
Idaho to NC Wyoming south to Nevada, Utah, and Colorado.
Occurrences Comments
There are 4 records in Wyoming (pers. comm. Walt Fertig WYNDD 1999). There is one specimen from Moffat County, Colorado at the CSU Herbarium (1999), and Weber and Wittmann (1996) report the distribution as Moffat to Mesa counties (Rio Blanco and Garfield counties are between Moffat and Mesa counties). The UTNHP does not have any occurrences in their database for this species, however they rank it an S3 in Utah (pers. comm. Ben Franklin UTNHP 1999 to Kim Fayette). It is assumed that there are at least 20 occurrences based on this rank. There are no locational data available for Nevada or Idaho.
Threat Impact Comments
This species grows on sandstone and dolomite ledges and similar rocky habitats so threats from humans may be relatively minimal (pers. comm. Michael Mancuso Idaho CDC 1999 and Walt Fertig WYNDD 1999 to Kim Fayette).
Ecology & Habitat

Habitat

In Utah, this species is found in blackbrush, sagebrush, pinyon-juniper, mountain brush, and mixed conifer communities (often in crevices) at 1220 to 3050 meters (Welsh et al. 1993). The Vascular Plants of Wyoming (Dorn 1992) reports that this species is found along cliffs and crevices.
