720101 Trientalis europaea L.
- L., Sp. Pl.: 344 (1753). Described from northern Europe. Type not designated (Jarvis 2007: 896).
2n=
>70 90-110+. - Far East (N). - Three reports.
Geography: European - Asian - amphi-Beringian.
Notes: Kelso: This complex has not been worked on, to my knowledge, with any more modern a look than Hultén gave it. I am pretty dubious about some of the distinctions being clear since I saw a lot of intergradation on this throughout Alaska. So, for what's worth: the Alaskan representatives that would be 'arctic' (e.g., coastal region along the Bering and Chukchi seas) would fall into subsp. arctica. Subspecies europaea may occur in interior Alaska as boreal.
Elven: Cholewa and Henderson revised the ALA material of Trientalis in 1993 in preparation for Flora of North America (Cholewa 2009). They divided it on subsp. arctica (frequent) and subsp. europaea (sparse). I have surveyed the material anew - with a 'European' background - and share their opinion that the vast majority of Alaskan specimens belong to subsp. arctica. This material differs from European subsp. europaea in at least three assumedly independent characters in leaf shape, leaf number, and pedicel glands. In addition, there are some less definite floral characters. Some specimens from the interior parts distinctly resemble subsp. europaea. Material (ALA) from East Chukotka also belongs in subsp. arctica. Some intermediates may occur on the Seward and Chukchi peninsulas. Cholewa (2009) discussed the matter but refrained from accepting races, mainly due to presence of intermediates. Intermediates do not prevent us from accepting races.
