Parsimony strict consensus tree of species in Lindsaea with dimidiate pinnules and anastomosing veins based on 22 morphological characters.
The bars in right indicate the systematic position (group) of each species inferred by molecular or morphological data. The asterisk indicates the position of the species is not confirmed by molecular data.

Fig 6.
Maximum likelihood phylogram of Lindsaea sect. Synaphlebium sensu lato obtained from combined trnL-trnF spacer and trnH-psbA spacer, associated on the right with the information of morphology, habit, and distribution center for the five clades.
Numbers at branches are Bayesian posterior probabilities, bootstrap values of maximum likelihood, and that of maximum parsimony, respectively. Only values over 50% for bootstrap and 0.95 for posterior probabilities are shown. Thick branches are highly supported (Bayesian PP > 0.95, MLBS > 70%, and MPBL > 70%). The two new species are in bold.
