Some plants of the family are most virulent poisons ; as,for example, the Manchineal-tree of the West Indies (HippomaneManicella), which is said even to destroy persons who sleep under itsshade ; and a drop of the juice blisters the hand. The hairs of somesj>ecies (such as our Cnidoscolus stimulosus) sting like Nettles. Box-wood is invaluable to the wood-engraver. The purple dye calledTurnsole is from Crozophora tinctoria. Another most importantproduct of this order is Caoutchouc, which is yielded by various plantsof different families; but the principal supply of the article (that ofPara, Demarara, and Surinam) is furnished by species of Ord. EmpetracCBB {Crowberry Family). Low, shrubby ever-greens, with the aspect of Heaths; the leaves crowded and acerose,. with small (dioecious or polygamous) flowers produced in the consisting of regular imbricated sepals, or represented by im-bricated bracts. Stamens few : pollen of four grains coherent inone, as in Heath. Ovaiy three- to nine-celled, with a single erectovule in each cell: style short or none : stigmas lobed and oftenlaciniated. Fruit a drupe, with from three to nine bony albuminous; the radicle inferior. — Ex. Empetrum, Ceratiola,Corema; unimportant plants. Probably no more than apetalousEricaceae ; but the stigmas are peculiar. 911. Ord.
