|discussion=<p>Recent collections of <i>Potentilla fragiformis</i> 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 <i>P. nana</i> but have the larger petals and longer styles of <i>P. fragiformis</i>.</p>
