This member of the
Asclepiadaceae* family was described by Spencer Le
Marchant Moore in 1908. It is found in Congo, Uganda,
Kenya, Tanzania and Zimbabwe, growing in woodlands in a well drained
soil with some water and some sun. The caudex can grow to 16
centimetres in diameter, the stem will grow to 20 centimetres. The
flowers are green and purple.
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 for the occurrence in a region inhabited by the ethnic group of
the Madi in Uganda.
