This member of the Euphorbiaceae family was given this name
by André Guillaumin in
1934. It is found in the south eastern Madagascar, growing in a well
drained soul with some water and lots of sun. The swollen roots can
grow to seven centimetres in diameter, and the vertical growing
stems up to 30 centimetres long. The flowers are from white over
pale yellow to red.
