Family- and genus-level circumscription of ferns in the suborder Aspleniineae (eupolypods II) has long been controversial, due in part to confusion about the relationship among the families Aspleniaceae and Athyriaceae. Recent studies have demonstrated that character states traditionally used to infer a close relationship between these two families are either symplesiomorphic or homoplastic, and re-examination of numerous taxa has led to the recircumscription of several clades, and the description of several new families and genera....
