Magnolia bawangensis Y. W. Law & R. Z. Zhou (in Y. H. Liu, Magnolias China, 34. 2004) belongs here 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).
One of us (Xia) considers that Magnolia mulunica is a distinct species of Lirianthe.
