When Hultén described Chrysanthemum arcticum subsp. polare, he mapped the two subspecies. Along the Bering Strait in Alaska, all the material appears to belong to subsp. polare, except at Norton Bay, where a specimen (ALA) could be attributed to subsp. arcticum. That population would be very disjunct from the range of the subspecies along the south coast of Alaska. The two subspecies do not overlap widely in North America.
