|discussion=<p>Scabrous-leaved <i>Ulmus rubra</i> is often confused with <i>U. americana</i>. Where ranges coincide, <i>U. rubra</i> may freely intergrade with <i>Ulmus pumila</i> Linnaeus, a widely introduced species.</p><!--
--><p>The red-rust, mucilaginous inner bark of <i>Ulmus rubra</i> is distinctive; its sticky slime gives this tree its common name of slippery elm. Native American tribes used <i>Ulmus rubra</i> 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.</p>
