This member of the
Euphorbiaceae family was given this name by Rodolfo Amando Philippi
in 1857. It is found in the Atacama Desert of Chile, growing in grit
or other well drained soil with little to some water (10 mm/year!
but fog) and lots of sun. The caudex can grow to eight centimetres
in diameter, the annual branches up to 25 centimetres. The flowers
are from pale yellow to dark violet.
This is a winter grower, but is
will probably use any chance given.
