Geography: North American (W) & North American (NE): CAN GRL.
Notes: Yurtsev: Taxonomical status of the Greenland population is to be specified. According to Soják (in comment), the type of Potentilla ranunculus Lange corresponds to that of P. glaucophylla Lehm. from Cordilleran North America.
Elven: Soják's view is shared by Ertter and Reveal in Ertter et al. (2011). In spite of the large gap between the (non-arctic) Cordilleran and the northeastern Canadian and Greenland plants, no morphological difference has been found to support two taxa, not even at subspecific level. Soják (1996) typified P. diversifolia and P. glaucophylla in a way that assigns the latter name to this species. The previously applied name P. diversifolia Lehm., Nov. Stirp. Pug. 2: 9 (1830), was typified on one plant on a mixed sheet in the Lehmann herbarium (PR-378126, otherwise with four specimens of current P. saximontana Rydb.). He stated this specimen to belong to the hybrid P. glaucophylla x hippiana.
