Bower (1890) defined antithetic alternation as an alternation "of two generations phylogenetically distinct, i.e., where a new stage (sporophyte) has been interpolated between pre-existing generations (gametophytes)." By contrast, he defined homologous alternation as an alternation "of two or more generations phylogenetically similar to one another, but differing in the presence or absence of sexual organs." Antithetic alternation, he believed, had probably arisen independently in several distinct phyla, including the Archegoniatae, the green Confervoideae (a taxon that included Coleochaete), the Florideae (red algae), and the Ascomycetous Fungi.
