--><p><i>Potentilla ovina</i> is here accepted as an implicit new name by J. M. Macoun for P. diversifolia var. pinnatisecta, in agreement with N. H. Holmgren (1997b). In contrast, B. C. Johnston (1980) considered the names heterotypic. <i>Potentilla ovina</i> has priority at the species rank over P. pinnatisecta by one month.</p>
