Wijkia carlottae, found in the Queen Charlotte Islands and Haida Gwaii, is closely related to W. tanytricha (Montagne) H. A. Crum of southeastern Asia, and the plants differ mainly in size and habit. Its exclusively vegetative reproduction indicates a clone that is slowly disseminated, because sporophytes and specialized vegetative reproduction are lacking.
