Discussion

Varieties 2 (2 in the flora).

Potentilla ovina 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. Potentilla ovina has priority at the species rank over P. pinnatisecta by one month.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

The center of distribution of Potentilla multisecta is northeastern Nevada and northwestern Utah; the best disposition of more northern populations, which tend to be hairier and more compact, is unresolved. Populations in eastern Idaho, southwestern Montana, and western Wyoming are components of an unresolved zone of apparent intergradation that also includes P. ovina var. ovina (sect. Multijugae), P. glaucophylla var. perdissecta (sect. Graciles), and members of sect. Subjugae. Significant variation also exists among populations in Nevada and Utah. Not included here are some subpalmate collections from Saskatchewan that would key to P. multisecta (for example, A. Breitung 4045, MO, RM), whose optimum disposition has yet to be resolved.
