R.J. Wang, a new monotypic genus for (Wall. ex Kurz) M.D.Yuan & R.J.Wang, new combination, is segregated from the - complex, based on morphological and molecular evidence. Phylogenetically, the new genus is sister to , from which it differs by a combination of morphological characters: herbaceous habit, terminal inflorescence with subtended leaves, heterostylous flowers, indehiscent fruits and pollen with double microreticulate tectum. A key to the genera of the complex in China is provided for further identification.
R.J. Wang是（Wall. ex Kurz）M.D.Yuan & R.J.Wang的一个新单型属，为新组合，基于形态学和分子证据从 - 复合体中分离出来。在系统发育上，这个新属是 的姐妹属，二者在形态特征组合上存在差异：草本习性、具苞叶的顶生花序、花柱异长的花、不裂的果实以及具双重微网状覆盖层的花粉。提供了中国 复合体各属的检索表以供进一步鉴定。
