Magnolia menlunica Q. W. Zeng & Y. W. Law (in Y. H. Liu, Magnolias China, 76. 2004) is of uncertain identity. It belongs to Lirianthe and is probably the same as an already published species but was not validly published because no Latin description or diagnosis was provided and no type was indicated (Vienna Code, Art. 36.1 and 37.1).
