The story of the word
Pliny reports that King Juba II of Mauretania named the plant after his personal physician Euphorbus, whose own name meant well-nourished. Linnaeus kept the tribute when he formalised the genus, making it one of the oldest surviving personal dedications in botany. The sap is genuinely dangerous to eyes, which is a reasonable thing to know before pruning one.
