|discussion=<p>B. P. G. Hochreutiner (1900) inexplicably merged <i>Hibiscus laevis</i> with the very different <i>H. coccineus</i>.</p><!--
--><p><i>Hibiscus laevis</i> has been recorded from Pelee Island in southernmost Ontario, but the 1904 collection is thought to have represented a short-lived population, as the species apparently has not since been found there (R. L. Stuckey 1968b). A report from the Bronx, New York (R. DeCandido 1991), well northeast of its closest previously known occurrence, is likely of an introduction or an escape.</p><!--
--><p>There are reports of recent northward spread of <i>Hibiscus laevis</i> along larger streams (C. C. Deam 1940; M. L. Roberts and R. L. Stuckey 1992; Stuckey 1968b; F. H. Utech 1970). R. B. Kaul (pers. comm.) reported similar upriver increases in Nebraska on the Elkhorn, Missouri, and Platt rivers. <i>Hibiscus laevis</i> sometimes forms natural hybrids with <i>H. moscheutos </i>subsp.<i> moscheutos</i>, usually in man-made habitats (O. J. Blanchard 1976).</p>
