Discussion
Scabrous-leaved Ulmus rubra is often confused with U. americana. Where ranges coincide, U. rubra may freely intergrade with Ulmus pumila Linnaeus, a widely introduced species.
The red-rust, mucilaginous inner bark of Ulmus rubra is distinctive; its sticky slime gives this tree its common name of slippery elm. Native American tribes used Ulmus rubra for a wide variety of medicinal purposes, including inducing labor, soothing stomach and bowels, treating dysentary, coughs, colds, and catarrhs, dressing burns and sores, and as a laxative (D. E. Moerman 1986). Various preparations utilizing it are still marketed.
