CASTOR-BEAN. Ricinus comraunis, Linn. Euphor- hiaccm. Figs. 325-330. By E. Mead Wilcox. Castor-oil is derived from the seeds or beans of ricinus, a coarse perennial plant (treated as annual in temperate climates), bear- ing large alternate palmately lobed leaves, flowers in large terminal clusters, and vari- colored seeds in prickly thrt' membered pods or burs. Tli flowers are unisexual and aiL gathered on a frequently much elongated axis, the staminate flowers generally being along the lower, the pistillate along the upper part of the inflores- cence; flowers without petals; stamens many; pistils three, two-parted, red. The castor-oil plant belongs m£p, to a family that has over four 'W/k. thousand species and is developed most highly in the tropics. It furnishes a great variety of useful products, among which may be named cassava or tapioca, caoutchouc and shellac. In the tropics, the castor-bean grows to a tree thirty to forty feet high, but in temperate regions it is a large annual. The original home of the castor-oil plant was in Africa or India, but it is now cultivated in all the warmer parts of the world, either for its oil or as an ornamental plant. The highest yield of oil is secured in the tropics, and it is grown only for ornamental purposes in the northern part of the corn-belt, where it would be a failure if grown for oil. It is said, however, that the oil secured from beans grown in the temperate climate of the United States is superior for medicinal purpo
