The taxonomic status and nomenclature of the hermaphrodite forms of Fucus (other than the alga currently known as F. spiralis L. and certain hybrid forms) usually included under the name Fucus inflatus L. by European authors, but under several specific names by N. American and some other authors, is discussed. It is considered that the numerous forms described are best interpreted for the present as forms of a single, extremely plastic and widely distributed species.
