• A recent phylogenenetic study of Aspleniaceae ( Murukami et al . 1999 ) shows that species segregated as " Camptosorus " and " Neottopteris " are nested within " Asplenium " and recommends that they be included in that genus, but suggests that " Hymenasplenium " ( including " Boniniella " ) and " Phyllitis " are distantly related to other " Asplenium " species and should be recognized at the generic level.
