Saxifraga punctata Linnaeus subsp. cascadensis Calder & Savile, Canad. J. Bot. 38: 425. 1960; S. nelsoniana D. Don subsp. cascadensis (Calder & Savile) Hultén; S. punctata var. cascadensis (Calder & Savile) C. L. Hitchcock

Leaf blades thin, not fleshy, margins 12-18-toothed. Inflorescences somewhat lax, tangled-appressed hairy. Pistils connate most of their lengths. Capsules 3-8 mm.

Flowering late spring-summer. Wet areas, stream banks; 800-2500 m; B.C.; Oreg., Wash.

Variety cascadensis has sometimes been confused with Micranthes odontoloma, probably because the petal spots of var. cascadensis fade on herbarium specimens. The more deeply toothed leaves, the compactness of the inflorescence, and the tangled inflorescence hairs clearly distinguish it from M. odontoloma. This variety is present in the Coast and Cascade ranges.
