Figure 5 Maximum likelihood phylograms of Dryopteris sect. Diclisodon based on nine plastid regions (A) and nuclear gene AK1 (B). ML ultrafast bootstrap support values (UFBS) and the posterior probabilities of Bayesian inference (BIPP) are indicated near nodes (UFBS/BIPP). The stars (*) indicate UFBS=100% or BIPP=1.00, the minus (-) indicate UFBS<50% or BIPP<0.50. The name of the new species is in bold.
