The other group has more extensive modifications to the flowers. Recent studies have placed a lot what of used to be Stapleideae under the Genus Ceropegia. There are other Genera remaining separate as well.
A trailing succulent vine and a hanging plant-what is considered "original" Ceropegia
Species of what used to be Stapelia, Orbea, Edithcolea and Stapelianthus , cactoid stem succulents(prostrate or erect) with (as the photos suggest) carrion flowers.Mainly from Africa. Genera like Hoodia, Huernia, Brachystelma ,Quaqua, Caralluma as well as the aforementioned can still be found under their old name in cultivation despite their recent reclassification.
Other aclepiad succulents are
the vine/trailing Hoya
And Fockea. Which would be the massive grey blob of a caudiciform plant.
These ones need some work...
