==Description==
 +
The species of the genus ''Euphorbia'' are the spurges, an incredibly diverse group of plants with milky white sap found from Africa to the tropical Americas.  The most famous species include the cactus-like succulents, such as ''E. abyssinica'', and the poinsettia, ''E. pulcherrima'', a beloved Christmas houseplant.  The genus name commemorates the ancient Greek physician Euphorbus, who allegedly used a spurge, possibly the Resin Spurge, ''E. resinifera'', to cure a stomach ailment of his employer, King Juba II of Numidia.  Speaking of whom, another species was named in the king's honor, ''E. regisjubae''.  The common name refers to the purgative effects the milky sap has upon ingestion.
