英文摘要	Subsect. Hirculoideae Engl. & Irmsch., belonging to Saxifraga sect. Ciliatae Haw., has high species richness. It can be divided into S. diversifolia, S. pseudohirculus, and S. sinomontana complexes based on morphological characteristics. The species with prominent leaf veins on the posterior leaf edge were placed in the S. diversifolia complex, which is mainly distributed on the eastern and southern margins of the Qinghai-Tibetan Plateau. In this study, 53 samples, representing 15 of the 33 described species in the S. diversifolia complex, were sequenced using the Restriction-site Associated DNA Sequence (RAD-seq) technique. A total of 111,938 high-quality SNP loci were screened to investigate the phylogenetic relationships within the S. diversifolia complex. The result of the neighbor-joining (NJ) tree shows that the S. diversifolia complex is a paraphyletic group. Despite of some inconsistencies as revealed by genetic structural analysis, clustering results of representative species reconstructed by both NJ and principal component analysis analyses support previous biogeographic and morphological evidences. In addition, long-distance gene flow events for 11 taxa were detected in the S. diversifolia complex, respectively from S. implicans 1 to S. implicans 2, S. diversifolia and S. maxionggouensis, and from S. maxionggouensis to S. nigroglandulifera. These findings may improve our comprehension of the phylogeny, classification, and evolution of the S. diversifolia complex.
