July 1935, leg. J.P. Anderson 2516. - Dryas sylvatica (Hultén) A.E. Porsild, Canad. Field-Naturalist 61: 191 (1947). |
| Notes | Elven and Murray: Yurtsev (PAF proposal) did not accept this northwestern North American race. It differs from subsp. integrifolia in several characters, occurs in different (drier and often more base-rich) sites but sometimes locally co-occurs, and occupies a range of its own, mainly in non-glaciated and now forested parts of Alaska and the Yukon Territory. Intermediates towards subsp. integrifolia are frequent but not to a degree that obscures the distinctness of the subspecies. |
