Y. Zou & X.W. Xu, a new species from Inner Mongolia, China, is described and illustrated. The phylogenetic position of the new species within the genus was analyzed based on eight chloroplast DNA fragments and an ingroup sampling of all Eurasian species of . The results showed that formed a separate branch between and the clade of , , , and . Based on molecular and geographical evidence, our study reveals that is closely related to and but differs from the former in the length and shape of the peduncle and seed size, and from the latter in the length of the peduncle, number of carpels per flower, and seed size. In addition, the karyotype analysis revealed that is octoploid, which is first reported within , further supporting as a new species.
邹Y.和徐X.W.描述并图示了来自中国内蒙古的一个新物种。基于八个叶绿体DNA片段以及该属所有欧亚物种的一个类群抽样，分析了新物种在该属内的系统发育位置。结果表明，该新物种在[具体物种A]和由[具体物种B]、[具体物种C]、[具体物种D]和[具体物种E]组成的分支之间形成了一个单独的分支。基于分子和地理证据，我们的研究表明，该新物种与[具体物种F]和[具体物种G]密切相关，但在花梗长度和形状以及种子大小方面与前者不同，在花梗长度、每朵花的心皮数和种子大小方面与后者不同。此外，核型分析表明该新物种是八倍体，这在[该属名称]内是首次报道，进一步支持了该新物种的地位。
