The genus Hibiscus has been determined to be paraphyletic, due, in part, to reliance on shared ancestral characters (i.e., symplesiomorphies) for defining the genus (Pfeil et al. 2002). It may be necessary to utilize many splinter genera to create a monophyletic Hibiscus. If this option is followed, it means that both H. moscheutos and H. trionum would be transferred to other genera.
