Asclepiadoideae

According to APG II, the Asclepiadaceae, commonly known as milkweed family,[2] is a former plant family now treated as a subfamily (subfamily Asclepiadoideae) in the Apocynaceae (Bruyns 2000).

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, 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.

gollark: Median might not actually be the right term either, but it's probably close enough.
gollark: There are two *medians*. There are not two *means*. This is why I said "mean" and not "average" a lot.
gollark: Sure. What is that modelling?
gollark: But in most cases they are motivated by real world examples of some kind.
gollark: Probability distributions are just functions, and you can define functions with all kinds of fun properties even if they aren't actually things you would likely encounter in real life.
