The former genus is endemic to China, including two species, has been under consideration for incorporation into the expanded genus s.l. in Gesneriaceae. The phylogenetic tree inferred from two DNA sequences (L-F and ITS) showed that this genus is deeply nested into s.l. However, the new tree from seven ones (B-L, H-, 132, C-D, L-F, T-L of chloroplast DNA and ITS regions) revealed that is the sister group of other of s.l. Furthermore, is morphologically different from other based on existing data. We suggest keeping as an independent genus in Gesneriaceae.
前一个属为中国特有，包含两个物种，一直在考虑将其并入广义的苦苣苔科属中。根据两个DNA序列（L-F和ITS）推断的系统发育树表明，该属深深地嵌套在广义的属中。然而，来自七个序列（叶绿体DNA和ITS区域的B-L、H-、132、C-D、L-F、T-L）构建的新树显示，该属是广义的其他属的姐妹群。此外，根据现有数据，该属在形态上与其他属不同。我们建议在苦苣苔科中保留该属作为一个独立的属。
