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.[2][3]
They form a group of perennial herbs, twining shrubs, lianas or rarely trees but notably also contain a significant number of leafless stem succulents. The name comes from the type genus Asclepias (milkweeds).
There are 348 genera, with about 2,900 species. They are mainly located in the tropics to subtropics,[4] especially in Africa and South America.
The florally advanced tribe Stapelieae within this family contains the relatively familiar stem succulent genera such as Huernia, Stapelia and Hoodia. They are remarkable for the complex mechanisms they have developed for pollination, which independently parallel the unrelated Orchidaceae, especially in the grouping of their pollen into pollinia. The fragrance from the flowers, often called "carrion", attracts flies. The flies pollinate the flowers.
Many new hybrids have been formed due to the unique fertilization method of the flowers.
Taxonomy
Gilbert Thomas Burnett in 1835 is considered to be the first botanist to recognize a primary division of the family Apocynaceae using the name Asclepiadeae,[5] an ending now used for tribes rather than subfamilies. In 2014, Endress, Liede-Schumann and Meve recognised five tribes within the subfamily.[6] A molecular phylogenetic study in 2019 confirmed the distinctness of the five tribes, which were related as shown in the following cladogram:[7]
