The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.

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.
Knema stylosa is a species of plant in the family Myristicaceae. It is a tree endemic to Borneo.

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.

Maytenus oleosa is a rare, willow-like, small tree in the family Celastraceae which is limited in habitat to lowland forests along the KwaZulu-Natal and Eastern Cape coasts of South Africa, particularly where there are streams or rivers. It is commonly associated with Gymnosporia bachmannii. The species is threatened by habitat loss and agricultural activities.
Nothofagus stylosa is a species of plant in the family Nothofagaceae. It is endemic to West Papua (Indonesia). It is a Critically Endangered species threatened by habitat loss.
