Rank ReasonsKnown from 3 adjacent southcentral Utah counties (Garfield, Kane, and Wayne). According to Cronquist (1994), "a narrowly limited endemic, locally abundant in the proper habitat."
Range Extent CommentsCronquist (1994) cited the distribution as "[b]arren (often gray) alkaline clay slopes in the pinyon-juniper zone ...; Garfield and Kane cos., Utah, notably in the drainage of the Paria and Escalante rivers.... [A] narrowly limited endemic, locally abundant in the proper habitat." Wayne Co. record according to Welsh et al. (1993), which also noted that the plants are found mainly on the Kaiparowits, Morrison, and Moenkopi formations.
Threat Impact CommentsThis taxon occurs in the southern Utah Redrock canyon country- a habitat that can be significantly affected by off-road vehicles and questionable road construction. Land in this area is in mixed ownership, including significant tracts of federal lands (although none report the presence of this taxon). In addition, this species grows near archealogical sites, and may recieve some protection as a byproduct of cultural protection. Erosion is a threat to the surface soils throughout this region.
