|discussion=<p>Quercus hemisphaerica flowers about two weeks later than sympatric Q. laurifolia (W. H. Duncan and M. B. Duncan 1988).</p><!--
--><p>Most authors have treated Quercus hemisphaerica as synonymous with Q. laurifolia. M. L. Fernald (1946) carefully examined the situation and concluded that Q. hemisphaerica is a distinct entity, but C. H. Muller (1951) argued that these two taxa "...are now certainly not separable even as varieties of the same species." Later (1970), Muller recanted by recognizing Q. hemisphaerica as a common component of stream terraces along the Gulf Coast.</p><!--
--><p>Quercus hemisphaerica reportedly hybridizes with Q. falcata (C. H. Muller 1970); with Q. arkansana, Q. inopina, Q. marilandica, Q. myrtifolia, Q. nigra, Q. phellos, Q. pumila, and Q. shumardii (D. M. Hunt 1989); and with Q. incana (producing Q. ×sublaurifolia Trelease), and Q. laevis (producing Q. ×mellichampi Trelease).</p>
