This member of the Euphorbiaceae family was given this name by Pierre Edmond Boissier in 1860. It is found in Botswana, Eswatini, Lesotho and South Africa, growing in a well drained soil with some water and lots of sun. The centre can grow to 18 centimetres in diameter, forming a 30 centimetre high and even up to 130 centimetre wide cushion, which will get yellow flowers.
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 'resembling the genera Clavaria '.
