|discussion=<p>Putative hybrids between <i>Quercus mohriana</i> Buckley and <i>Q. grisea</i> Liebmann are problematic and highly polymorphic. They are restricted to zones of contact between limestone, the preferred habitat of <i>Q. mohriana</i>, and igneous substrates, the preferred habitat of <i>Q. grisea</i>, or sometimes on dolomite, in western Texas.</p>
