Resumen

Examination of several entire thalli of Eisenia from Isla Guadalupe, Baja California, Mexico, shows that E. desmarestioides and E. masonii, two species previously described from that island by Setchell and Gardner, represent growth forms of a single species, for which the name E. desmarestioides is retained. Desmarestioides-type blades develop from outgrowths initiated basally from pseudostipes. They subtend masonii-type blades, which develop from outgrowths initiated from pseudostipes distal to the desmarestioides initials. The significance of this dimorphism is not known.
