Circaea canadensis B. S. Walters

C. lutetiana of Michigan Flora.

Dry (e.g., oak-hickory) or more often rich moist deciduous forests or edges of forests, frequently in ravines and wet spots; sometimes in swamps, even with tamarack, or along streams; often somewhat weedy in disturbed settings.

Recognition of C. canadensis follows Boufford (2005); American populations are subsp. canadensis and Eurasian plants are subsp. quadrisulcata (Maxim.) Boufford.
