This member of the
Asclepiadaceae* family was described by Friedrich Richard
Rudolf Schlechter in 1894. It is found in KwaZulu-Natal, South
growing in a well drained soil with some water and some
sun. The caudex might grow to twelve centimetres or more, the vines to
two meters or more. The flowers are green.
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 after Henry G. Flanagan, 1861-1919, a South African citrus
farmer, interested in botany.
*)Accordantly to the latest taxonomic system; APG IV 2016, Asclepiadaceae is now part of the Apocynaceae.
