Euphorbia rogeri, N.E.Br.
This member of the
Euphorbiaceae family was described by William Aiton in 1789. It is found in
northern Africa and on the Canary Islands, growing in grit or an
other well drained soil with some water and lots of light. The stem can grow to
fifteen centimetres in diameter,
and up to 200 centimetres height. The flowers are pale green.
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 'with a fragrant wax, resin'.
