Euphorbiaceæ (Buxus sempervirens) Box.


Many species of this order are acrid and poisonous, and have been used for poisoning arrows. The Castor-oil plant (Ricinus palma-christi), and the plant that yields that most violent purgative, Croton-oil (Croton tiglium), are of this species; also the Box-tree, from which that useful wood, known as box-wood, is obtained.
