--><p><i>Quercus acerifolia</i> is known only from four localities in Arkansas: Magazine Mountain, Logan County; Porter Mountain, Polk County; Pryor Mountain, Montgomery County; and Sugarloaf Mountain, Sebastian County (N. Stoynoff and W. J. Hess 1990; G. P. Johnson 1992, 1994). Some specimens suggest hybridization with <i>Q. marilandica</i> and/or <i>Q. velutina</i>, but no hybrids have been reported.</p>
