Range Extent20,000-2,500,000 square km (about 8000-1,000,000 square miles)
Number of Occurrences21 - 80
Rank ReasonsAlthough this species has a fairly wide range and is probably not too threatened, specific information is lacking. Therefore, this species is given a global rank of G3G4, rare or uncommon (G3) at worst or stable at best. If or when more information is gathered, the global rank may be further refined.
Range Extent CommentsExcept for the population in Oregon, this species is limited to California, Siskiyou County, which is adjacent to Oregon, southward to Kern County and possibly San Bernardino County.
Occurrences CommentsIn Oregon, it is known from one occurrence. California Natural Diversity Data Base does not address this species, and it is assumed to be too common to be on any of their lists. In California, it is reported from 101 observations, which included data from herbaria collection labels, species lists, U.S. Forest Service ecology plots and literature surveys. There are 21 different counties noted from the California dataset with 17 of the observations dated post 1960 (CalFlora 1999). The estimate of 21-100 occurrences may be conservative with the truer number being over 100.
Threat Impact CommentsThe Oregon population is threatened by grazing, and it is also near the Pacific Crest Trail although it is not clear if this is a concern or not.
