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.
Strobilanthes is a genus of about 350 species of flowering plants in the family Acanthaceae, mostly native to tropical Asia and Madagascar, but with a few species extending north into temperate regions of Asia. Many species are cultivated for their two-lipped, hooded flowers in shades of blue, pink, white and purple. Most are frost-tender and require protection in frost-prone areas. The genus is most famed for its many species which bloom on long cycles of several years, such as Strobilanthes wightii which blooms every thirteen years.
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.
Dicliptera is a genus of flowering plants in the bear's breeches family, Acanthaceae. 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.
The genus Asystasia belongs to the family Acanthaceae and comprises 59 species found in the tropics of Africa, Asia, Australia, and New Guinea. It includes the weedy species Asystasia gangetica.
Acanthopale is a plant genus of shrubs or subshrubs in the Acanthaceae plant family. The genus name is based on the classic Greek words for thorn ákantha and stake palum. Some species in the genus are cultivated as ornamental plants.
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.
Blepharis is a genus of plant in family Acanthaceae. It contains around 128 species found in seasonally dry to arid habitats from Africa through Arabia to Southeast Asia. In section Acanthodium, there are 13–15 species that use the C4 carbon fixation pathway. Phylogenetic analysis suggests that this pathway evolved up to three times independently in the genus over the last five million years.
Brachystephanus is a genus of flowering plants in the family Acanthaceae. It includes 21 species native to tropical Africa and Madagascar.
Neuracanthus is a genus of plants in the family Acanthaceae.
Pseuderanthemum is a genus of plants in family Acanthaceae with a pantropical distribution.
Rhinacanthus is a genus of plants in the family Acanthaceae. It contains the following species :
Sclerochiton is a genus of plants in the family Acanthaceae.
Mimulopsis is a genus in the flowering plant family Acanthaceae with about 30 species native to tropical Africa and Madagascar.
Stenandriopsis is a genus of flowering plants belonging to the family Acanthaceae. It includes 20 species native to tropical Africa and Madagascar. Molecular phylogenies have placed the Old World Stenandriopsis apart from New World Stenandrium, and the genus is accepted in a classification of the family Acanthaceae published in 2022.
Mellera is a genus of flowering plants belonging to the family Acanthaceae.
Rungia is a genus of flowering plants belonging to the family Acanthaceae.
