Synonym — Gilenia Trifoliata Moench.
Other Common Names — Gilenia, bowman's-root, false ipecac, western dropwort, Indian-hippo.
Habitat and Range — Indian-Physic is native in rich woods from New York to Michigan, south to Georgia and Missouri.
Description of Plant — The reddish stems of this slender, graceful perennial of the rose family (Rosaceae) are about 2 to 3 feet high, several erect and branched stems being produced from the same root. The leaves are almost stemless and trifoliate; that is, composed of three leaflets. They are ovate or lanceolate, 2 to 3 inches long, narrowed at the base, smooth and toothed. The nodding, white pinkish flowers are few, produced in loose terminal clusters from May to July. The five petals are long, narrowed or tapering toward the base, white or pinkish, and inserted in the tubular, somewhat bell shaped, red tinged calyx. The seed pods are slightly hairy.
At the base of the leaf stems are small leaflike parts, called stipules, which in this species are very small, linear and entire. In the following species, which is very similar to trifoliatus and collected with it, the stipules, however, are so much larger that they form a prominent character, which has given rise to its specific name, stipulatus.
Indian Physic (Porteranthus Trifoliatus).
Porteranthus stipulatus (Muhl.) Britton (Syn. Gillenia stipulacea Nutt.) is found in similar situations as P. trifoliatus, but generally farther west, its range extending from western New York to Indiana and Kansas, south to Alabama, Louisiana and Indian Territory. The general appearance of this plant is very similar to that of P. trifoliatus. It grows to about the same height, but is generally more hairy, the leaflets narrower and more deeply toothed, and the flowers perhaps a trifle smaller. The stipules, however, will generally serve to distinguish it. These are large, broad, ovate, acute at the apex, sharply and deeply notched and so much like leaves that but for their position at the base of the leaf stems they might easily be mistaken for them.
With the exception of the name American ipecac applied to this plant, the common names of Porteranthus trifoliatus are also used for P. stipulatus. The roots of both species are collected and used for the same purpose.
