CLUTIA, in botany: A genus of the gynandria order, belonging to the dicæia class of plants; and in the natural method ranking under the 38th order, Tricœce. The male calyx is pentaphyllous, the corolla pentapetalous: the calyx and corolla of the female as in the male; the styles are three, and the capsule is trilocular with a single seed. There are three species, all of them natives of warm climates. They are evergreen shrubby plants, rising six or eight feet high, garnished with simple leaves, and greenish-white quinquepetalous flowers. They are propagated by cuttings in spring or summer, planting them in pots of light earth, plunged in a hot-bed. The plants must always be kept in a stove.
Dr Wright, in his account of the medicinal plants of Jamaica, says that the clusia elutheria is the same as the cascarilla and cleatheria of the shops. Other medical writers have supposed them to be distinct barks, and they are sold in the shops as different pro-
ductions. Linæus's croton cascarilla, Dr Wright observes, is the wild rosemary shrub of Jamaica, the bark of which has none of the sensible qualities of the cascarilla.
