From: Using a multilocus phylogeny to test morphology-based classifications of Polystichum (Dryopteridaceae), one of the largest fern genera

Fig. 1

Simultaneous-analysis maximum likelihood tree of Polystichum based on five chloroplast markers (psbA-trnH intergenic spacer, rbcL gene, rps4-trnS intergenic spacer, trnL intron, and trnL-F intergenic spacer) of 177 accessions representing ca. 140 species of Polystichum and 13 species of the closely related four genera as outgroups. Maximum parsimony jackknife (MPJK) values/maximum likelihood bootstrap (MLBS) values/Bayesian inference posterior probability (BIPP) values are along the branches. Dashed branches indicate the disproportional branch lengths
