Taxonomic CommentsAllen et al. (2019) combine Doellingeria and Eucephalus into a single North American genus, with "all new combinations...made in Doellingeria, which has priority."

Rank ReasonsEucephalus paucicapitatus is a perennial herb that has a limited range in the coastal regions of Washington state, in the Olympic Mountains on the Olympic Peninsula, and British Columbia, in the subalpine zones of Vancouver Island. With targeted surveys, historic collections and suitable habitat, are likely to yield additional extant occurrences. Currently between 20 and 30 are believed to be extant globally. Threats are not well documented but not expected to be severe, as most occurrences are on protected lands. Recent surveys do show healthy, reproducing individuals capable of dispersal to favorable sites. Long term, climate change could be an increasing threat.
Range Extent CommentsEucephalus paucicapitatus occurs on the Olympic Peninsula of Washington (U.S.A.) and the subalpine region of mountains on Vancouver Island in British Columbia (Canada).
Occurrences CommentsThere are likely around 6 extant occurrences in Washington and in British Columbia, there are less than 20.
