Gymnosporia is an Old World genus of plants, that comprise suffrutices, shrubs and trees. It was formerly considered congeneric with Maytenus, but more recent investigations separated it based on the presence of achyblasts and spines, alternate leaves or fascicles of leaves, an inflorescence that forms a dichasium, mostly unisexual flowers, and fruit forming a dehiscent capsule, with an aril on the seed. It is dioecious, with male and female flowers on separate plants.

Maytenus is a genus of flowering plants in the family Celastraceae. Members of the genus are distributed throughout Central and South America, Southeast Asia, Micronesia, and Australasia, the Indian Ocean and Africa. They grow in a very wide variety of climates, from tropical to subpolar. The traditional circumscription of Maytenus was paraphyletic, so many species have been transferred to Denhamia and Gymnosporia.
