1894. It is found
in Eswatini and South Africa, growing in a well drained soil with
some water and some to lots of sun. The caudex can grow to 50
centimetres in diameter (some claim), the entire plant to 30 or even
100 centimetres in
flowers are bright green and brownish.
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 Dr. Ernest E. Galpin, 1858-1941, a South African banker
and amateur botanist.
