This member of the Euphorbiaceae family was described by John Gilbert Baker in 1880. It is found in western and central Madagascar, growing in a well drained soil with some water and lots of sun. The caudex can grow to eight centimetres in diameter, the plant will grow to fifteen centimetres height - 25 if the caudex is exposed. The flowers are white.
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 'having flowers like a Primula (primrose)'. Unfortunately, I also have a page with the synonym: Euphorbia subapoda, Henri Ernest Baillion 1887.
