NatureServe Conservation Status

Rounded Global Status Rank: G3 - Vulnerable

Reasons: 5 EOs documented, but difficult to determine from map # of EOs on Aleutian Islands, and arctic area undercollected. Rank changed to 'GU' 94-04-27 due to question about Claytonia porsildii, a separate species to which the name Claytonia arctica was previously applied. Rank changed in 1995 to 'G3' due to personal communication of LEM with Rob Lipkin (AKHP): when the two species are distinguished each merits a G3 rank.

Names and Taxonomy

Taxonomy

Comments: A species of Northeast Asia, with outlying populations in westernmost Alaska. This species was misunderstood by Porsild (1975) to include another, more widespread species which was recently described and named C. porsildii by Yurtsev in a Russian publication.
