Asclepiadoideae is a plant subfamily of Apocynaceae. It differs from others by having a very complex sexual apparatus and a complicated pollination procedure. They are easyly recognisable by five-lobed flowers. The lobes are joined together at the base of flower (corolla). There are about 2000 species of Asclepiadaceae split into some 300 genera, of which about half are succulent. Succulent plants are particularly interesting to me, especially the group named stapeliads.
Asclepiads grow worldwide, from jungles of Indonesia to deserts and steppes of Africa.
