|discussion=<p><i>Quercus geminata</i> occurs in Cuba as putative hybrids.</p><!--
--><p>Although some recent authors prefer to treat <i>Quercus geminata</i> as a variety of <i>Q. virginiana</i>, the two species are easily separable and rarely intergrade through most of the broad range in which they are sympatric. Apparently this is primarily because of habitat separation, but additionally <i>Q. geminata</i> flowers much later than <i>Q. virginiana</i> in any given geographic area. At the northern extreme of the range of <i>Q. geminata</i>, apparent intermediates with <i>Q. virginiana</i> are more common, possibly because flowering times of the two species overlap to a greater extent because of slower warming in the spring. Scattered intermediates also occur where the two species are sympatric on sands in coastal Mississippi.</p>
