Discussion

Of conservation concern.

Variety perdissecta is confined to the northern Rocky Mountains of extreme southwestern Alberta, south into eastern Idaho, western Montana, and western Wyoming. The variety is also reported from Okanogan County, Washington. Apparent intergradation occurs with pinnate-leaved Potentilla ovina var. decurrens (sect. Multijugae).
