Subspecies 7 (1 in the flora). The status of Potentilla supina in North America is open to question, given the otherwise Eurasian and northern African distribution of the species and ease of transport by migratory waterfowl. Although North American material has commonly been treated as a distinct species (P. paradoxa), E. Hultén and M. Fries (1986) went so far as to consider P. supina introduced in North America. The use of subspecies within a broadly defined P. supina follows J. Soják (1987, 1993) and is also adopted by A. Kurtto et al. (in J. Jalas et al. 1972+, vol. 13).

Recent collections of Potentilla fragiformis in Alaska on the coast of the Bering and Chukchi seas have confirmed historical reports (P. A. Rydberg 1908d) of this Beringian species in North America. Dwarf plants from St. Lawrence Island are somewhat intermediate to P. nana but have the larger petals and longer styles of P. fragiformis.
