Asclepiads or Asclepiadoideae are a subfamily in the Apocynaceae, with about 2900 species. There are lots of leafless stem succulents but also perennial herbs, shrubs, lianas or rarely trees. They produce remarkable flowers, for the complex mechanisms they have developed for pollination. Many species produce an unusual fragrance, often called "carrion", and attracts flies for pollination.
This hoodia is different in its genus because of its thicker stems, less branched. It blooms with yellow-maroon flowers. It is native to an area Prince Albert, in South Africa. Some authors consider it a synonym of H. gordonii.
