Hymenasplenium is one of three genera of ferns in the Aspleniaceae (spleenwort family), in the eupolypods II clade of the order Polypodiales.[1][2] The others are Hemidictyum and Asplenium. Hymenasplenium was segregated because it is a natural grouping with differing rhizome morphology – dorsiventral v. radial for the rest of Asplenium, differing chromosome count – x=39 v. x=36 for the rest of Asplenium, and a clear monophyletic grouping based on genetic analysis. It was confirmed as a sister group to Asplenium in a 2015 molecular study of the genera.[3]
