在日本已报道了11种本地天竺葵属植物，其中一些包括种下类群。尽管已经使用常规方法进行了系统发育分析（即，叶绿体片段和核糖体DNA测序），由于缺乏遗传多态性，种下水平的关系尚未阐明。本研究从日本及周边地区（如日本东北部、东北部、东北部）采集了22种天竺葵属植物的标本，中国大陆、韩国、俄罗斯和台湾），并使用叶绿体基因组测序和全基因组单核苷酸多态性进行了详细的系统发育分析。目前的分类和系统发育关系之间的一些差异，在我们的分析中阐明。结果表明，Geralgesium tripartum complex是并系的，Geralgesium onoeif.yezoense是Geralgesium reinii的异名，与Geralgesium erianthan与Geralgesium reinii的亲缘关系较近。reinii。特别是G.在网络分析中，三分种（tripartitumvar.hastatum）位于黄毛菊和黄毛菊之间。因此，我们建议G. tripartitumvar. hastatum应作为一个独立种处理，G.只有一个野线虫应转移到G.毛蕊花
Eleven nativeGeraniumspecies have been reported in Japan, several of which include infraspecific taxa. Although phylogenetic analyses have been conducted using conventional methods (i.e., chloroplast fragment and ribosomal DNA sequencing), relationships at the infraspecific level have not been elucidated due to a lack of genetic polymorphisms. We collected specimens of 22Geraniumtaxa from Japan and peripheral areas (e.g., mainland China, South Korea, Russia, and Taiwan), and performed detailed phylogenetic analyses using chloroplast genome sequencing and genome-wide single-nucleotide polymorphisms. Some discrepancies were observed between the current taxonomy and the phylogenetic relationships elucidated in our analyses. TheGeranium tripartitumcomplex was found to be paraphyletic, andGeranium onoeif.yezoense, which is synonym ofGeranium reinii, was found to be more closely related toGeranium erianthumthan toG. reinii. In particular,G. tripartitumvar.hastatumlocated at intermediate position betweenGeranium thunbergiiandGeranium wilfordiiin the network analysis. Therefore, we suggest thatG. tripartitumvar.hastatumshould be treated as an independent species, and thatG. onoeif.yezoenseshould be transferred toG. erianthum.
