Apocynaceae is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here.
The Asclepiadoideae are a subfamily of plants in the family Apocynaceae. Formerly, they were treated as a separate family under the name Asclepiadaceae, e.g. by APG II, and known as the milkweed family.
Hoodia is a genus of flowering plants in the family Apocynaceae, under the subfamily Asclepiadoideae, native to Southern Africa.
Stapeliinae is a subtribe of flowering plants within the tribe Ceropegieae of the subfamily Asclepiadoideae of the family Apocynaceae. The subtribe comprises about 35 genera, including both the stem-succulent "stapeliads" and the horticulturally popular genera Brachystelma and Ceropegia. The largest number of genera are native to Africa, but a more limited number of genera are widespread in Arabia and Asia. Historically, a similarly circumscribed taxon was treated as a separate tribe, Stapelieae.
Stapelia is a genus of low-growing, spineless, stem succulent plants, predominantly from South Africa with a few from other parts of Africa. Several Asian and Latin American species were formerly included but they have all now been transferred to other genera. The flowers of certain species, most notably Stapelia gigantea, can reach 41 cm (16 inches) in diameter when fully open. Most Stapelia flowers are visibly hairy and generate the odor of rotten flesh when they bloom.
The genus Huernia consists of perennial, stem succulents from Eastern and Southern Africa and Arabia, first described as a genus in 1810.
Duvalia is a succulent plant genus in the subfamily Asclepiadoideae, in the family Apocynaceae (dogbane).
Larryleachia is a genus of stapeliad succulent flowering plants in the family Apocynaceae.
The genus Quaqua falls within the tribe of plants known collectively as stapeliads. All stapeliads, including Quaqua, are Old World stem succulents.
Microloma is a small genus of Ceropegia-like twiners and twiggy bushes occurring in mainly arid or fynbos regions in South Africa. They are generally nondescript when not in bloom, but the flowers of most species are incongruously decorative.
Fockea is a genus of succulent scrubs native to Africa south of the equator. They are members of the Asclepiadoideae (milkweeds), a subfamily of the dogbane family Apocynaceae. Of the six recognized species, only the two most widely distributed extend north of southern Africa, with F. multiflora reaching as far north as Tanzania and F. angustifolia reaching to southern Kenya. Fockea are known as water roots, a reference to the bulbous caudex characteristic of most species, which is also edible in at least some species.
Pseudolithos is a genus of succulent flowering plants of the family Apocynaceae, indigenous to arid areas of Somalia, Yemen and Oman.
Tromotriche is a genus of plant in family Apocynaceae. It is native to southern Africa.
Stapeliopsis is a genus of succulent plants in the family Apocynaceae, native to southern Africa.
Echidnopsis is a genus of succulent, cactus-like plants in the family Apocynaceae, first described as a genus in 1871. They are native to eastern Africa and the Arabian Peninsula.
Notechidnopsis is a group of plants in the family Apocynaceae first described as a genus in 1985. It contains only one recognized species, Notechidnopsis tessellata, native to Cape Province in South Africa.
Duvalia elegans is a small succulent plant species, in the family Apocynaceae. It is the type species of the genus Duvalia, and it is endemic to the Western Cape Province, South Africa.
Duvalia vestita is a small succulent plant species, in the family Apocynaceae, indigenous to the southernmost part of the Western Cape Province, South Africa.
