Subspecies cuneifolia is generally taller and more robust than subsp. saxifragifolia. It is known in Alaska from the outermost Aleutian Islands of Attu and Agattu; in Asia it occurs south through the Pacific Rim to the northern Japanese Islands. This subspecies predominates in Asia; the homostylous one occurs there only as rare outliers. The situation is reversed in Alaska, where the homostylous taxon is geographically widespread as far south as Vancouver Island.
