This member of the Asclepiadaceae* family was given this name by Stephan Friedrich Ladislaus Endlicher in 1839. It is found in south-western South Africa, growing in a well drained soil with some water and some sun. The caudex develops in the ground, and only in the ground. If it is raised, it will almost only develop downwards, in the ground. Given prime conditions for a 100 years or two, you will end up with a 60 centimetre caudex with five meter vines and white flowers.
The genera name after Charles Focke, 1802-1856, a Dutch botanist, collecting especially in Surinam. The species name means 'from the Cape' - of South Africa. As the synonym crispa implies, it has crisped margined leaves.
