James Bruce, 1936
Benin, Burkina, Cameroon,
Central African Republic, Ghana, Guinea, Ivory Coast, Mali (Togo, Nigeria,
Liberia, Sierra Leone?)
Sand - Mix - Grit
This member of the Asclepiadaceae* family
was given this name by James Bruce in 1936. It is found in Benin, Burkina,
Cameroon, Central African Republic, Ghana, Guinea, Ivory Coast and Mali.
I guess it is in Togo, Nigeria, Liberia and Sierre Leone, unless they
have eaten them all. It is growing in a well drained soil from sand over
a mix to gravel with some water and lots of sun. The caudex can grow to
five centimetres in diameter and ten centimetres long, the entire plant
to ten centimetres in height. The flowers are pale green..
The genera name from Greek
rhaphis; 'beet-root' and akme; 'sharpness' possibly
referring to the taste of the roots - haven't tried yet. I could do
with some help on the species
name! Could be named after some Vigne, but I fail to figure who.
*)Accordantly to the latest taxonomic system; APG IV 2016, Asclepiadaceae is now part of the Apocynaceae.
