The subtribe Saussureinae is a highly speciose group with more than 600 species distributed in the Northern Hemisphere and is particularly species‐rich at the high mountains of central and eastern Asia. Saussurea and Jurinea are the two main genera described within the subtribe. However, up to 15 satellite genera are recognized in some recent taxonomic treatments with an analytical viewpoint. For the first time, we carried out a complete sampling to clarify generic boundaries based on a well‐resolved phylogeny of Saussureinae. We employed a Hyb‐Seq technique that targets 1061 nuclear conserved ortholog loci designed for Compositae. After a filtering of potential paralogs, 588 loci were retained to infer phylogenetic trees under concatenation and coalescence approaches. High branch support resolution was recovered at the generic level, but a non‐monophyletic pattern was detected for most of the genera as they are currently circumscribed. Accordingly, we propose a new generic delimitation based on the three main clades recovered in the backbone tree, which are also in agreement with morphological evidence: Dolomiaea, Saussurea, and Jurinea. Following this classification into three genera, 18 new combinations are proposed. This new genus delineation will be used as a basis for future evolutionary studies in the Saussureinae.

Saussureinae群落的一般边界（菊科：Cardueae）：Hyb-Seq数据的见解

Saussureinae属是一个非常特殊的种群，在北半球分布有600多个物种，在中亚和东亚的高山地区物种特别丰富。雪莲和尤里娜是子部落中描述的两个主要属。然而，从分析的角度来看，在最近的一些分类学处理中，最多可以识别15个卫星属。我们首次进行了完整的采样，以基于良好解析的Saussureinae系统发育来阐明通用边界。我们采用了Hyb-Seq技术，该技术的目标是为菊科设计的1061个核保守直系同源基因座。在筛选可能的旁系同源物后，保留了588个基因座，以通过级联和合并方法推断系统发育树。在一般水平上已恢复了较高的分支支持分辨率，但由于目前已被限制，因此大多数属均检测到非单株模式。因此，我们基于在主干树中恢复的三个主要进化枝，提出了一种新的通用定界，多洛米亚，索苏拉和胡里纳。在将此分类分为三个属之后，提出了18种新组合。这种新的属将被用作雪莲科未来进化研究的基础。
