Discussion

Anemone quinquefolia var. interior Fernald is an often used, although illegitimate, name for A. quinquefolia var. bifolia. This taxon, characterized by its villous flowering stems, is scarcely worthy of varietal recognition inasmuch as local populations may have plants referable to both var. bifolia and var. quinquefolia (C. S. Keener 1975b).

Intergradation of characteristics between Anemone quinquifolia var. minima and var. quinquefolia, and between var. quinquefolia and A. lancifolia frequently makes identification extremely difficult in the area where the taxa overlap.
