FIG. S3. Phylogenetic placement of Stenodraba within tribe Eudemeae. A. Maximum clade credibility species tree (MCCT) estimated from nuclear ribosomal ITS and two chloroplast DNA regions (trnL-F, trnH-psbA) using the multispecies coalescent method implemented in *BEAST. Bayesian posterior probability values >50 % are given at each node. B. Filtered supernetwork generated in SplitsTree using 1000 Bayesian posterior trees per each nuclear ITS and plastid (trnL-F/trnH-psbA) dataset, and filtering the splits to show only those present in a minimum of 35% input trees. The start indicate the crown node of tribe Eudemeae.

补充图S3　狭果荠属（Stenodraba）在Eudemeae族（Eudemeae）内的系统发育定位。A. 采用*BEAST软件中实现的多物种溯祖法，基于核糖体核内转录间隔区（ITS）与两个叶绿体DNA区域（trnL-F、trnH-psbA）构建最大分支可信物种树（Maximum clade credibility species tree, MCCT），各节点标注了大于50%的贝叶斯后验概率值。B. 针对核ITS与质体（trnL-F/trnH-psbA）的两套数据集，各使用1000棵贝叶斯后验树，在SplitsTree软件中生成并经筛选的超网络：仅保留至少出现在35%输入树中的拆分分支。图中的星号指示Eudemeae族的冠节点。
