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.
The docks and sorrels, genus Rumex, are a genus of about 200 species of annual, biennial, and perennial herbs in the buckwheat family, Polygonaceae. Members of this genus are very common perennial herbs with a native almost worldwide distribution, and introduced species growing in the few places where the genus is not native.
Anthriscus (chervils) is a common plant genus of the family Apiaceae, growing in Europe and temperate parts of Asia. It comprises 15 species. The genus grows in meadows and verges on slightly wet porous soils. One species, Anthriscus cerefolium is cultivated and used in the kitchen to flavor foods.
Justicia is a genus of flowering plants in the family Acanthaceae. It is the largest genus within the family, with over 900 accepted species. 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.
Acanthus mollis, commonly known as bear's breeches, sea dock, bear's foot plant, sea holly, gator plant or oyster plant, is a species of plant in the family Acanthaceae and is native to the Mediterranean region. It is a leafy, clump-forming perennial herb, with a rosette of relatively large, lobed or toothed leaves, and purplish and white flowers on an erect spike.
Plumbago is a genus of 23 species of flowering plants in the family Plumbaginaceae, native to warm temperate to tropical regions of the world. Common names include plumbago and leadwort.
Mendoncia mollis is a plant species in the family Acanthaceae. It is a liana native to west-central and southeastern Brazil.
Hygrophila, commonly known as swampweeds, is a genus of flowering plants in the acanthus family, Acanthaceae. There are about 80 to 100 species, of which many are aquatic plants. The genus is distributed across the tropical and subtropical world. It is one of only two genera in its family that contains aquatic plants, the other being Justicia. The genus is treated in the tribe Hygrophileae, which is noted as being in need of revision at the genus level, meaning the current taxonomic boundaries of Hygrophila are likely to change in the future.
Dinteracanthus is a genus of flowering plants belonging to the family Acanthaceae.
Blepharis dhofarensis is a species of plant in the family Acanthaceae. It is a shrub that grows to around 5m tall and is found in Oman and Yemen. Blepharis dhofarensis grows on wet escarpment woodlands and it prefers dense thickets on steep slopes. It is threatened by habitat loss. Recent molecular work has placed it in the genus Acanthus instead of Blepharis.
Brachystephanus is a genus of flowering plants in the family Acanthaceae. It includes 21 species native to tropical Africa and Madagascar.
Brillantaisia is a genus of plants in the family Acanthaceae. They are native to the African tropics and subtropics, including Madagascar. They may grow from 20 cm to 2 m in height. Their hirsute stems are square in cross-section and their heart-shaped leaves have an opposite arrangement. Their purple or white pea-like flowers produce long, cigar-shaped seed pods. They reproduce easily from seeds or vegetatively. One species, B. lamium, is invasive in Queensland.
Sclerochiton is a genus of flowering plants in the family Acanthaceae. It includes 18 species native to tropical and southern Africa.
Acanthus ebracteatus is a species of shrubby herb that grows in the undergrowth of mangroves of south-east Asia. Common names include sea holly and holly mangrove.
Acanthus spinosus, the spiny bear's breech, is a species of flowering plant in the family Acanthaceae, native to southern Europe, from Italy to western Turkey. It is an herbaceous perennial growing to 150 cm (59 in) tall by 60–90 cm (24–35 in) wide. The deeply cut leaves have spiny margins, and in early summer it bears erect, 1 m (3 ft) long racemes of white flowers with maroon bracts.
Acanthus ilicifolius, commonly known as holly-leaved acanthus, sea holly, and holy mangrove, is a species of shrubs or herbs, of the plant family Acanthaceae, native to Australia, Australasia, and Southeast Asia. It is used as medicine in asthma and rheumatism.
Rhizophora mucronata is a species of mangrove found on coasts and river banks in East Africa and the Indo-Pacific region.
Ruspolia is a genus of flowering plants belonging to the family Acanthaceae.
Acanthus austromontanus is a species of flowering plant in the genus of Acanthus. It is native to southwestern Tanzania and typically exists as a shrub.
