Hairy Arnica (Arnica mollis): Single collection from Shakes Lake in 1993. Even assuming collection is correctly assigned, it is not clear whether this species is established in the region, as Southeast Alaska would appear to be near the northwestern-most limits of the regular range (though there are a handful of collections from further west in Alaska). However, other collections from northwestern British Columbia suggest the possibility that this species could occur at the northern margins of the region.
