|discussion=<p>The Alaskan populations of <i>Trientalis europaea</i> have been segregated as T. arctica or <i>T. europaea</i> var. aleutica, based primarily on the number and size of leaves. E. Hultén (1927–1930, vol. 4) reduced these to <i>T. europaea</i> <i></i>subsp.<i> arctica</i>; he indicated that they (along with populations from eastern Siberia) are merely “geographic races.” He later (1968) mapped them as discrete entities. Other taxonomists (e.g., S. L. Welsh 1974) found intermediates, which I corroborated by examination of herbarium specimens. I believe that a conservative approach is warranted until additional research is undertaken.</p>
