This member of the Asclepiadaceae* family was described by Friedrich Richard Rudolf Schlechter in 1895. It is found in Eswatini, Mozambique, South Africa and Zimbabwe, growing in a well-drained soil with some water and lots of sun. The caudex can reach 20 centimetres or more in diameter, the vines will reach for 75 centimetres. The deciduous flowers are a pale green star with a purple centre. It can be reproduced both by seeds and cuttings.
The genera name from Greek rhaphis; 'beet-root' and akme; 'sharpness' possibly referring to the taste of the roots - haven't tried yet. The species name means 'lying' or 'outstretched' for the growth form. *)Accordantly to the latest taxonomic system; APG IV 2016, Asclepiadaceae is now part of the Apocynaceae. A plant I found at Kakteen Haage.
