NeighborNet split network inferred using the concatenated nuclear data, showing conflict among nuclear loci. The currently recognized sections are indicated by colored circles: orange = sect. Holochloa; blue = sect. Heuchera; green = sect. Bracteatae; pink = sect. Rhodoheuchera.基于串联核基因数据构建的邻网分裂网络（NeighborNet split network），呈现了核基因座间的演化冲突。当前公认的分类组以彩色圆圈标注：橙色代表全颖组（sect. Holochloa）；蓝色代表矾根组（sect. Heuchera）；绿色代表苞片组（sect. Bracteatae）；粉色代表红花矾根组（sect. Rhodoheuchera）。
