Plants 8-15 cm, (elongating in fruit). Leaf blades 3-6 × 0.8-1 cm. Inflorescences 3-9-flowered. Flowers heterostylous; corolla lobes 12-25 mm. 2n = 22. Flowering summer. Moist meadows on acidic bedrock; 0-100 m; Alaska; Asia. 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.
