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.
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao, roselle and durian. There are also some genera containing familiar ornamentals, such as Alcea (hollyhock), Malva (mallow), and Tilia. The genera with the largest numbers of species include Hibiscus, Pavonia, Sida, Ayenia, Dombeya, and Sterculia.
An IUCN Red List Critically Endangered species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as Critically Endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild.

Ayenia loxensis is a species of flowering plant in the family Malvaceae. It is found only in Ecuador. Its natural habitat is subtropical or tropical dry shrubland.
Ayenia obtusata is a species of flowering plant in the family Malvaceae. It is found only in Ecuador. Its natural habitat is subtropical or tropical moist montane forests from 200 to 2,800 meters elevation.
Ayenia sparrei is a species of flowering plant in the family Malvaceae. It a shrub found only in Ecuador.
Hypericum scopulorum is a species of flowering plant in the family Hypericaceae. It is endemic to Socotra, an island archipelago that is part of Yemen. It is a common plant in shrubland habitat, and it is a dominant species in some areas along with Cephalocroton and another local endemic, Libinhania rosulata.
Helicia is a genus of 110 species of trees and shrubs, constituting part of the plant family Proteaceae. They grow naturally in rainforests throughout tropical South and Southeast Asia, including India, Sri Lanka, Indochina, Peninsular Malaysia to New Guinea and as far south as New South Wales.
The Guajira–Barranquilla xeric scrub is a xeric shrubland ecoregion in Colombia, Venezuela, and the ABC Islands, covering an estimated area of 150,000 km2 (58,000 sq mi). Rainfall varies from 125 to 600 mm, and the median temperature is 37 °C (99 °F).
Ayenia is a genus of flowering plants in the mallow family, Malvaceae. It includes 216 species of subshrubs, shrubs, small trees, and lianas. They are native to the tropical Americas and southwestern United States, tropical Africa, and tropical Asia.
Ayenia compacta is a species of shrub in the mallow family known by the common name California ayenia.

Ambrosia cheiranthifolia is a rare species of flowering plant known by the common names South Texas ambrosia and Rio Grande ragweed. It is native to the coast of South Texas and the Mexican states of Tamaulipas and Coahuila. It occurs in coastal prairie, grassland, and mesquite shrubland habitat. It has declined because its native habitat has been cleared for development, with remaining open savanna invaded by non-native grasses such as buffelgrass. Today there are perhaps 20 populations remaining, but some of these may have very few genetic individuals because the species is clonal, with many cloned plants attached by one rhizome. It is not certain that the plant still exists in Mexico. This is a federally listed endangered species of the United States.
Ayenia limitaris is a rare North American species of flowering plant in the mallow family known by the common names Rio Grande ayenia, Texas ayenia, and Tamaulipan kidneypetal. It is native to an area straddling the Rio Grande in Mexico and the United States. Today it is known from far southern Texas and far northern sections of the Mexican states of Coahuila and Tamaulipas. It has become rare because most of its habitat has been degraded or destroyed. There are perhaps four populations remaining in Texas and two in Mexico, for a total of 1000 individual plants at most. It is a federally listed endangered species of the United States.
Byttnerioideae is a subfamily of the flowering plant family Malvaceae.
Ayenia elegans is a species of flowering plant in the family Malvaceae. It is native to southeastern Asia, including Bangladesh, Myanmar, south-central China (Yunnan), eastern India, Laos, Thailand, Vietnam, and Peninsular Malaysia.
