Abstract;On the basis of three species in three genera (Menyanthes, Nephrophyllidium and Nymphoides) of Menyanthaceae we found that the family has a thick, 10- to 25-cell-layered integument as in Asteraceae and Goodeniaceae, and not a thin, 3- to 6-cell-layered integument as in Pentaphragmataceae and Campanulaceae sensu lato. In the light of a molecular phylogenetic tree of Campanulales sensu lato published elsewhere, the result suggests that the evolution from the thin to the thick integument occurred in a common ancestor with Asteraceae, Goodeniaceae, and Calyceraceae although the last family is not known yet with respect to integumentary thickness.
