|discussion=<p>Putative hybrids between <i>Quercus bicolor</i> and <i>Q. macrocarpa</i> are common in areas of contact. The hybrids tend to have more deeply lobed leaves and varying degrees of development of awns as a fringe along the margin of the acorn cup. Such characteristics occur sporadically throughout many populations of <i>Q. bicolor</i>; in some cases they may occur because of subtle introgression.</p><!--
--><p>The Iroquois used <i>Quercus bicolor</i> in the treatment of cholera, broken bones, consumption, and as a witchcraft medicine (D. E. Moerman 1986).</p>
