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.
