Discussion

Artemisia carruthii is closely related to members of the A. ludoviciana complex, with which it may intergrade.

As circumscribed here, Artemisia alaskana is known from northwestern North America. The type specimen of A. alaskana is atypical, with longer peduncles and narrower leaf lobes than are found in most populations.
