|discussion=<p>The bark of this species (quercitron) is rich in tannins and was once an important source of these chemicals used for tanning leather. (The yellow dye obtained from the bark is also called quercitron.)</p><!--
--><p>Native Americans used <i>Quercus velutina</i> medicinally for indigestion, chronic dysentery, mouth sores, chills and fevers, chapped skin, hoarseness, milky urine, lung trouble, sore eyes, and as a tonic, an antiseptic, and an emetic (D. E. Moerman 1986).</p><!--
--><p><i>Quercus velutina</i> reportedly hybridizes with <i>Q. coccinea</i>, <i>Q. ellipsoidalis</i> (= Q. ×paleolithicola Trelease), <i>Q. falcata</i> [= Q. ×willdenowiana (Dippel) Zabel] (= Q. ×pinetorum Moldenke)], <i>Q. ilicifolia</i> (= Q. ×rehderi Trelease), <i>Q. imbricaria</i> (= Q. ×leana Nuttall), <i>Q. incana</i>, <i>Q. laevis</i>, and <i>Q. laurifolia</i> (= Q. ×cocksii Sargent, although E. J. Palmer [1948] challenged the validity of this claim), <i>Q. marilandica</i>, <i>Q. nigra</i>, <i>Q. palustris</i> (= Q. ×vaga E. J. Palmer & Steyermark), <i>Q. phellos</i> (= Q. ×filialis Little), <i>Q. rubra</i>, <i>Q. shumardii</i>, and possibly <i>Q. arkansana</i> (D. M. Hunt 1989).</p>
