|discussion=<p>Individual trees with leaves softly pubescent abaxially may be classified as <i>Quercus phellos</i> forma intonsa Fernald; however, such leaves are known to occur on second-flush shoots from twigs bearing typical leaves.</p><!--
--><p><i>Quercus phellos</i> reportedly hybridizes with <i>Q. coccinea</i> (W. W. Ashe 1894); with <i>Q. ilicifolia</i> (= Q. ×giffordi Trelease) and <i>Q. incana</i> (E. J. Palmer 1948); and with <i>Q. marilandica</i>, <i>Q. nigra</i>, <i>Q. pagoda</i> (= Q. ×ludoviciana Sargent), <i>Q. palustris</i>, <i>Q. rubra</i>, <i>Q. shumardii</i>, and <i>Q. velutina</i>. D. M. Hunt (1989) cited evidence of hybridization also with <i>Q. hemisphaerica</i>, <i>Q. imbricaria</i>, <i>Q. laurifolia</i>, and <i>Q. pumila</i>.</p>
