|discussion=<p>Trees with shallow cups covering ca. one-fourth of the nut are treated as Quercus shumardii var. shumardii; those with more deeply rounded cups covering ca. one-third of the nut are treated as Q. shumardii var. schneckii (Britton) Sargent. Quercus shumardii var. stenocarpa Laughlin was described from several trees in Missouri and Illinois having ellipsoid acorns that were covered less than one-third their length by very small (5.5-7 mm high × 12.5-18 mm wide), shallow cups (K. Laughlin 1969).</p><!--
--><p>Quercus shumardii reportedly hybridizes with Q. buckleyi, Q. falcata (= Q. ×joori Trelease), Q. hemisphaerica, Q. imbricaria (= Q. ×egglestoni Trelease), Q. laevis, Q. laurifolia, Q. marilandica, Q. nigra, Q. palustris (= Q. ×mutabilis E. J. Palmer & Steyermark), Q. phellos (= Q. ×moultonensis Ashe), Q. rubra, and Q. velutina (= Q. × discreta Laughlin).</p>
