Nakai (Apioideae, Apiaceae), originally found in the Wuling Mountain of China, was initially described as a species but later treated as a variety of Vest ex Spreng. However, researchers have recently found that it is more closely related to DC. In this study, we conducted morphological and phylogenetic analyses as well as chromosome counting to determine the taxonomic status of B.sibiricumvar.jeholense (Nakai) Chu. Our results showed that B.sibiricumvar.jeholense and share common features (i.e., bracteoles 5 and stem solid) that distinguish both from B.sibiricumvar.sibiricum. The chromosome number of B.sibiricumvar.jeholense was found to be the same as in (i.e., 2n = 12), whereas the chromosome number of B.sibiricumvar.sibiricum was 64. A phylogenetic tree based on complete chloroplast genome data revealed a close relationship between B.sibiricumvar.jeholense and . Finally, B.sibiricumvar.jeholense and were mainly found to differ in plant height, number of stems, and middle stem leaves. Based on this evidence, we propose a new combination: Bupleurumchinensevar.jeholense (Nakai) Q.R.Liu & L.H.Wang.
北柴胡(伞形科,芹亚科)最初发现于中国的武陵山,最初被描述为一个物种,但后来被视为Vest ex Spreng.的一个变种。然而,研究人员最近发现它与DC.的关系更为密切。在本研究中,我们进行了形态学和系统发育分析以及染色体计数,以确定柴胡北柴胡变种(Nakai)Chu的分类地位。我们的结果表明,柴胡北柴胡变种和[此处原文缺失相关名称]具有共同特征(即小苞片5片且茎实心),这使其与柴胡原变种区分开来。发现柴胡北柴胡变种的染色体数与[此处原文缺失相关名称]相同(即2n = 12),而柴胡原变种的染色体数为64。基于完整叶绿体基因组数据构建的系统发育树显示柴胡北柴胡变种与[此处原文缺失相关名称]关系密切。最后,主要发现柴胡北柴胡变种和[此处原文缺失相关名称]在株高、茎数和中部茎生叶方面存在差异。基于这些证据,我们提出一个新组合:柴胡北柴胡变种(Nakai)Q.R.Liu & L.H.Wang。
