A revision of three endemic Chinese species of Pternopetalum (P. cardiocarpum, P. delavayi and P. sinense), based on herbarium material and field observations, is presented. Examination of critical diagnostic characters showed that there is a single morphologically well-delimited species here treated as P. delavayi. Pternopetalum cardiocarpum and P. sinense are its taxonomic synonyms.
