Differs from dwarfed Potentilla reptans in sterile state by basal leaflets arising directly from top of petiole, not from near base of sub-basal pair.

Hybrids
- ?Potentilla x beckii Murr (= Potentilla crantzii x Potentilla tabernaemontani) might be the identity of intermediate plants in Midwest Yorks, South Aberdeen and Cheviot, the last far from either species. Intermediacy is shown in stipule-shape, flower-size and growth-habit. Chromosome number: 2n=61-64.
