Spurges (genus Euphorbia) are a very large and diverse worldwide group of plants, belonging to the spurge family, or Euphorbiaceae.
The botanical name Euphorbia derives from the Greek Euphorbus, physician of king Juba II of Numidia (52-50 BC - 23 AD), in whose honour – or in allusion to his swollen belly – a certain plant he might have used, possibly Euphorbia resinifera, was named.
The genus Euphorbia is one of the largest and most complex genera of flowering plants and several botanists have made unsuccessfully attempts to subdivide the genus into numerous smaller genera.
