Horse Balm. Rich-Weed. Stone-Root

Collinsonia Canadensis. Mint Family.

One to three feet high. Leaves.--Opposite; large; ovate; toothed; pointed. Flowers.--Yellowish; lemon-scented; clustered loosely. Calyx.--Two-lipped; the upper lip three-toothed, the lower two-cleft. Corolla.--Elongated; somewhat two-lipped; the four upper lobes nearly equal, the lower large and long, toothed or fringed. Stamens.--Two (sometimes four, the upper pair shorter), protruding diverging. Pistil.--One, with a two-lobed style. In the damp rich woods of midsummer these strong-scented herbs, with their loose terminal clusters of lemon-colored, lemonscented flowers, are abundant. The plant was introduced into England by the amateur botanist and flower-lover, Collinson, after whom the species is named. The Indians formerly employed it as an application to wounds.
