“…Therefore, it is demonstrated that none of S. diversifolia , S. pseudohirculus , and S. sinomontana complexes are monophyletic in view of the conclusion of this work and Yuan et al. ( 2023 ). Meanwhile, S. pseudohirculus and many members of the S. diversifolia complex were also highly accepted as being clustered in a clade in her results.…”

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.

Micranthes octopetala (Nakai) Y.I.Kim & Y.D. Kim et al. 2015, which belongs to the family Saxifragaceae, is a perennial herb endemic to Korea. M. octopetala was originally treated as a synonym of M. manchuriensis . However, in 2015, molecular phylogenetic analysis confirmed that M. octopetala is an independent species. In this study, the plastid genome of M. octopetala was sequenced for the first time, and the taxonomic position of this species was identified. The complete plastid genome of M. octopetala has a total length of 149 751 bp (large single copy: 83 083 bp; small single copy: 17 196 bp; inverted repeat: 24 736 bp), containing 130 genes, including 79 CDS, 30 tRNAs, and 4 rRNAs. Moreover, the absence of intron in the rpl 2 gene, which is a common feature of Saxifragaceae, was confirmed. Phylogenetic analysis based on 79 protein-coding genes from 21 species revealed that M. octopetala belongs to the genus Micranthes, being a sister to other Micranthes species. The plastid genome of M. octopetala obtained in this study provides fundamental information for future studies on the genus Micranthes .
