Needs some water and lots of sun. The swollen stems can grow up to nine centimetres in diameter, and reach a length of 30 centimetres. The flowers are yellow.
The genera name; Euphorbia dates back to the first century BC, where King Juba II of Mauritania used it in a reference to his doctor, Euphorbos, and that name was kept as a generic name by Carl von Linnaeus. The species name means 'living on quarts'. A wild plant by H. van der Werff, MoBot.com.
