This member of the Euphorbiaceae family was given this name by Rodolfo Amando Philippi in 1860. It is found in a small costal area of northern Chile, growing in a well drained soil with some winter rain and lots of sun. The caudex will disappear by time, and the plant will grow into a small bush, 120 centimetres in height with pale 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 from Latin; lacti; 'mix' and Latin flua 'impurities'. This is a winter grower
