Molecular analyses
A total of 12 taxa were included in the molecular phylogenetic analysis (Fig. 3). The resulting concatenated matrix dataset contained 3895 bp. The 50% majority-rule consensus tree based on maximum likehood bootstraps (ML) and Bayesian posterior probability (PP) of three chloroplast regions (matK , psba-trnH , psaJ-rpl33 ) both showed that three accessions of the new species grouped together (PP=100, ML=99) and were sister to Saxifraga geifolia with well support (PP=87.77, ML=84).
