Discussion

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.
