Manglietia sapaensis N. H. Xia & Q. N. Vu sp. nov. (Magnoliaceae) from Vietnam

A new species of the family Magnoliaceae, Manglietia sapaensis N. H. Xia & Q. N. Vu from Lao Cai Province, northern Vietnam, is described and illustrated. The well marked species appears to be most closely related to M. garrettii Craib, but differs in being a smaller tree, with shorter petioles not pulvinate at base, leaf‐lamina oblong to oblong‐elliptic, white flowers, and pubescent gynoecium.
