Trees, shrubs and herbs. Lvs. opposite, somewhat verticillate, entire. Stipules between the petioles, sometimes resembling the leaves. Calyx tube more or less ad-herent to the ovary; limb 4 to 5-cleft. Corolla regular, inserted upon the calyx tube, and of the same number of divisions. Stamens inserted upon the tube of the corolla, equal in number and altornate with its segments. Ovaries 2 (rarely more)-<vl!ed. Style single or partly divided. Fr. various. Seeds one, few. or many in each cell. (Fig. 183.)

Genera 330, species 2800. It is generally divided into two suborders. viz.. Stellatea and Cin-choncie, to which a third, Logunien- (which has fow representatives :at the North) is appended by

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.
