. Bulletin. Agriculture. 84 AMERICAN ROOT DRUGS. GOLDTHREAD. Coptis trifotia (L.) Salisb. Other common ««»tcs.—Coptis, cankerroot. mouthroot, yellowroot. Habitat and range.—Thi^i pretty little perennial is native in damp, mossy woods and bogs from Canada and Alaska south to Maryland and Minnesota. It is most common in the New England States, northern New York and Michigan. in Canada, where it frequents the dark sphagnum swamps, cold bogs, and the shade of dense forests of cedars, pines, and other evergreens. Description of plant.—Anyone familiar with this attractive little plant will j!gree that it is well named. The roots of goldthread, running not far beneath the surface of the ground, are indeed like so many tangled threads of gold. The plant in the general appearance of its leaves and flowers very closely re- t^embles the strawberry plant. It is of low growth, only 3 to 6 inches in height, and belongs to the crowfoot family (Ranunculacete). The leaves are all basal, and are borne on long, slender stems; they are evergreen, dark green and shining on the lipper surface and lighter green beneath, divided into three parts, which are prominently veined and toothed. A single small, white, star-shaped flower is borne at the ends of the flowering stalks, ap- pearing froin May to Au- gust. (Fig. 11.) The 5 to 7 sepals or lobes of the calyx are white and like petals, and the petals of the corolla, 5 to 7 in number, are smaller, club shaped, a n d yellow at the base. The seed pods are stalked, oblong, compressed, spreading, tipped with the persist- ent style, and containing small black seeds. Description of root.— Goldthread has a long, slender, creeping root, which is much branched and fre- quently matted. (Fig. 11.) The color of these roots is a bright golden yellow,. As found in the stores, goldthread consists usually of tangled masses of these golden-yellow roots, mixed with the leaves and stems of the plant,, but the root is the part prescribed for use
