Acanthaceae is a family of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions. The four main centres of distribution are Indonesia and Malaysia, Africa, Brazil, and Central America. Representatives of the family can be found in nearly every habitat, including dense or open forests, scrublands, wet fields and valleys, sea coast and marine areas, swamps, and mangrove forests.
Justicia is a genus of flowering plants in the family Acanthaceae. It is the largest genus within the family, encompassing around 700 species with hundreds more as yet unresolved. They are native to tropical to warm temperate regions of the Americas, India, and Africa. The genus serves as host to many butterfly species, such as Anartia fatima. Common names include water-willow and shrimp plant, the latter from the inflorescences, which resemble a shrimp in some species. The generic name honours Scottish horticulturist James Justice (1698–1763). They are closely related to Pachystachys.
Aphelandra is a genus of over 200 species of flowering plants in the family Acanthaceae, native to tropical regions of the Americas.
Ruellia is a genus of flowering plants commonly known as ruellias or wild petunias. They are not closely related to petunias (Petunia) although both genera belong to the same euasterid clade. The genus was named in honor of Jean Ruelle (1474–1537), herbalist and physician to Francis I of France and translator of several works of Dioscorides.
Dicliptera is a genus of flowering plants in the bear's breeches family, Acanthaceae. It includes 223 species native to the tropics and subtropics worldwide. Well-known synonyms include Peristrophe and Dactylostegium.
Lepidagathis is a genus of flowering plants in the family Acanthaceae. It includes 151 species native to the tropics of the Americas, sub-Saharan Africa, south and southeast Asia, southern China, Malesia, and New Guinea.
Stenandrium is a genus of flowering plants in the family Acanthaceae native to the Americas, with 50 species of perennial herbs ranging from the southern United States to northern Argentina and central Chile.
Anisotes is a genus of Afrotropical plants in the family Acanthaceae. The genus is morphologically similar to Metarungia, from which it differs mainly in the dehiscence of the fruit capsule, and the nature of the placenta. Placentas remain attached to the inner surface of fruit capsules in Anisotes.
Carlowrightia is a genus of flowering plants in the bear's breeches family, Acanthaceae. Members of the genus, commonly known as wrightworts, are mainly small shrubs bearing inflorescences of lily-like flowers. They are native to the Americas, ranging from the southwestern United States through Mexico and Central America, and in Ecuador. Many species are native to western North America. The genus was named for the American botanist Charles Wright.

Stenostephanus is a genus of plants in the family Acanthaceae. It includes 94 species native to the tropical Americas, ranging from northeastern Mexico to Bolivia and southeastern Brazil.
Tetramerium is a genus of plants belonging to the family Acanthaceae. It is found in the Americas, ranging from the southwestern United States to Bolivia, especially in tropical dry forests. Christian Gottfried Daniel Nees von Esenbeck first described the genus in 1846 after collecting two species on the journey of HMS Sulphur.
Dyschoriste is a genus of flowering plants in the family Acanthaceae. It includes 98 species native to the tropics and subtropics of the Americas, sub-Saharan Africa, and southern Asia. Members of the genus are commonly known as snakeherb.
