Euphorbia milii (crown of thorns, Christ plant, Christ thorn) is a species of flowering plant in the spurge family Euphorbiaciae, native to Madagascar. The species name commemorates Baron Milius, once Governor of Réunion, who introduced the species to France in 1821.[1] It is suspected that the species was introduced to the Middle East in ancient times, and legend associates it with the crown of thorns worn by Christ.[1]
