This member of the Euphorbiaceae family was described by Pierre L. Boiteau in 1941. It is found in northern Madagascar, growing in a well drained soil with little to some water and lots of sun. The stems can grow to four centimetres in diameter, and up to 70 centimetres height. The flowers are greenish-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 from André Louis Joseph Edmond Armand Guillaumin, 1885-1974, a French botanist.
