Holotype (DAO): Canada: the Yukon Territory, the British Mountains, the Mount Sedgwick area, 19. July 1962, leg. J.A. Calder 34478. |
| Notes | Zhmylev: Micranthes razshivinii is a Yukon Territory and northeastern Alaskan hypoarctic species, similar to M. calycina but differs from it in glabrous inflorescence, spathulate leaves with fewer than 7 teeth, and long rhizome. Murray and Elven: An inspection of material from Alaska and the Yukon Territory (ALA) gave support to two parapatric taxa: Micranthes razshivinii in the Yukon Territory and the eastern and northeastern parts of Alaska west to 152 W in both the Alaska and Brooks ranges, overlapping with M. calycina which occurs westwards from 149 W in both ranges and farther south in Alaska, but perhaps not in the Yukon Territory. |
