This member of the Euphorbiaceae family was given this name by Ferdinand Albin Pax in 1894. It is found in Zimbabwe, Mozambique, Zambia, Malawi and Tanza, growing in a well drained sandy soil with some water and lots of sun. The caudex can grow to four centimetres in diameter, 20 or even 30 long, the entire plant to 35 centimetres in above ground. The flowers are green.
It is said this plant is very sensitive to water while it is dormant. Keep it dry!
