The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
Cynometra is genus of tropical forest trees with a pantropical distribution. It is particularly important as a forest component in west Africa and the neotropics. Cynometra alexandri (muhimbi) is a familiar timber tree of central and east Africa. The genus is a member of the subfamily Detarioideae. It has been suggested that Cynometra is polyphyletic and is in need of revision. In 2019, beside description of 4 new species, Aleksandar Radosavljevic suggested that the species formerly recognized as Maniltoa should be included in this genus and some of the mainland tropical African species excluded from this genus because of their jointed pedicels and dehiscent fruits.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss.

Madhuca diplostemon is a species of flowering plant in the family Sapotaceae, endemic to India. It is a threatened tree species of the Western Ghats whose original specimens were collected in 1835, and it was considered extinct for 184 years until a single living specimen was discovered in a sacred grove in Kollam district, when scientists at the Jawaharlal Nehru Tropical Botanic Garden and Research Institute (JNTBGRI) identified the tree as Madhuca diplostemon rather than the common attilippa.
Psychotria beddomei is a species of plant in the family Rubiaceae. It is endemic to Kerala in India.
Syzygium beddomei is a species of plant in the family Myrtaceae. It is endemic to Tamil Nadu in India.
A tree in the family Fabaceae, Cynometra ramiflora is found in mangroves and flooded forests from New Caledonia in the western Pacific west to Queensland in Australia, New Guinea, Island Southeast Asia, and Tropical Asia as far west as India. Its wood is used for construction and fuel, and parts of plant are ascribed medicinal use.
