Torrey and Gray. The species of the first suborder, Stellatese, are common in the northern parts of both continents; the other suborder prevails chiefly in warm or torrid regions.
Properties. - A very important family, furnishing many useful products. The madder, one of the most important of dyes, is furnished by the root of Rubia tinctoria. A similar coloring matter is possessed by several species of Galium. Peruvian bark, a powerful febrifuge, is the product of several species of Cinchona, viz., C. mieranthia, C. condaminea, C. Ianceolata, C. mag-nifolia, ifce, all natives of Peru. Their febrifugal properties depend upon the presence of two alkalies, Cinchonia and Quinia, both combined with Kinic ;acid. Ipecacuanha, the prince of emetics, is the product of the root of Cephaelis Ipecacuanha, a little shrubby plant with creeping roots, in the damp forests of Brazil. Several other species of Cincnonea; afford substitutes for the true Ipecac.
Coffee is the hard albumen of the seeds of Coffea Arabica, a tree of moderate size, with a light brown trunk, and a conical shaped head. Leaves shining, light green. Flowers white, fragrant. The berries are black when ripe. Coffee is said to have been used in Ethiopia from time immemorial. In Paris and London it seems not to have been in general use earlier than the year 1700.
