Figure 2 - Topology from ML and BI analyses of Dryopteris species using six marker regions consisting of 3734 total bases (psbA-trnH, rbcL-accD, rbcL, trnL-trnF, trnP-petG, rps4-trnS and matK). The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. Bootstrap values are specified at the branch nodes (cut off >50%) / Bayesian РР. Dryopteris blanfordii subsp. nigrosquamosa and closely related species are marked with a blue rectangle.
