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.
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.
Cynanchum is a genus of about 300 species including some swallowworts, belonging to the family Apocynaceae. The taxon name comes from Greek kynos and anchein, hence the common name for several species is dog-strangling vine. Most species are non-succulent climbers or twiners. There is some evidence of toxicity.
Duvalia is a succulent plant genus in the subfamily Asclepiadoideae, in the family Apocynaceae (dogbane).
Tridentea is a genus of succulent plant in the family Apocynaceae, endemic to southern Africa.
Strychnos madagascariensis, the black monkey orange, is an African tropical and sub-tropical tree belonging to the Loganiaceae family. It is a tree with characteristically large fruit but can confused with some other species of the genus.
Syncolostemon (sagebushes) is a genus of plants in the family Lamiaceae, first described in 1838. It is native primarily to South Africa, with some species in other parts of sub-Saharan Africa, plus one species in India.
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.
Raphionacme is a plant genus in the family Apocynaceae, first described as a genus in 1842. The genus is found primarily in Africa, with one species on the Arabian Peninsula.
Rhytidocaulon is a plant genus in the family Apocynaceae, first described in 1962. It is native to northeastern Africa and the Arabian Peninsula
Huernia hystrix, the porcupine huernia, is a species of flowering plant in the family Apocynaceae, native to southeastern Africa. A succulent, it has gained the Royal Horticultural Society's Award of Garden Merit.
