- Magnolia champacifolia J. E. Dandy ex F. Gagnepain, sp. nov., originally described, but invalidly published in 1938, is validated here by designating the flowering sheet as the holotype. Otherwise, a new species of Magnolia L., M. lamdongensis V.T. Tran, N.V. Duy & N.H. Xia, sp. nov. from southern Vietnam is described and illustrated. It is distinguished from the closely related M. champacifolia J. E. Dandy ex F. Gagnepain, sp. nov., and M. albosericea Chun & Tsoong by its leaf blades narrowly ovate, glabrous, apex long acuminate, petiole c. 3 cm long, tepals short and glabrous, peduncle c. 3 cm long and densely papillate when young, and gynoecium glabrous.
