Discussion
Potentilla sterilis was collected from the coast of Newfoundland in 1928 (A. M. Ayre s.n., GH); no recent documentation of occurrence is known (J. Maunder, pers. comm. to L. Brouillet). Although previously treated as native (M. L. Fernald 1950; E. Hultén and M. Fries 1986), this status has been challenged (for example, A. Kurtto et al. in J. Jalas et al. 1972+, vol. 13). According to H. A. Gleason and A. Cronquist (1991), the species is also rarely introduced in the eastern United States; no vouchers have been seen.
Potentilla sterilis is superficially similar to strawberry (Fragaria) but lacks the fleshy fruit; other differences include stolon structure, anther morphology, and style length and attachment.
