Simultaneous-analysis maximum likelihood tree with parsimony jackknife values above each branch, and maximum likelihood bootstrap values below each branch. If a clade was resolved in one analysis but not the other, “/” is used to indicate which analysis that clade was not resolved in. Dashed branches indicate the disproportional branch lengths. The species in red color indicate those that are currently not in the genus Dryopteris but resolved as members of Dryopteris in this study. Major morphological and/or palynological synapomorphies are indicated in blue. Geographical provenances are indicated in green.
