FIGURE 1 in Lepisorus youxingii (Polypodiaceae), a new fern species from Guangxi, China
FIGURE 1. Majority consensus tree of Lepisorus obtained in Bayesian inference based on the combined molecular dataset including sequences of rbcL, rbcL−atpB, rps4−trnS, trnL−F, matK, psbZ, rpl32−trnP, and trnT. Numbers above each branch are support values in the order of SH−aLRT/UFBoot/PP. Stars indicate SH−aLRT, UFBoot =100% or PP=1.0. The dash (–) indicates a node with SH−aLRT<50%, UFBoot<80% or PP <0.5.
