Plants called "Cercis gigantea Cheng et Keng f." (in Wei & He, Fl. Zhejiang. 3: 279. 1993) may represent a distinct species, but too little material was available to be certain. This needs further study. The name was not validly published because no Latin description or diagnosis was provided and no type was indicated (Vienna Code, Art. 36.1, 37.1).
