During the research on the family Magnoliaceae from Vietnam, the authors found that Chen, B. L., H. P. Nooteboom (1993) in "Notes on Magnoliaceae III: The Magnoliaceae of China" indicated the spedes Magnolia championii Benth. for Flora of Vietnam, but its distribution as well as collections were not mentioned. Moreover, in other monograph on Magnoliaceae in Vietnam such as "Checklist of Plant Species of Vietnam" (Nguyen Tien Ban, 2003) and "An Illustrated Flora of Vietnam" (Pham Hoang Ho, 1999) also not recorded this species for Vietnam. By specimen examination on the herbaria of Vietnam and overseas, the authors officially record that Magnolia championii is distributed in provinces of Hai Phong, Quang Ninh, Nghe An, Ha Tinh and Thua Thien Hue. Its information on taxonomic treatment, description, etc. of Magnolia championii are given in this paper.
