|discussion=<p>For many years the name <i>Quercus texana</i> was erroneously used for <i>Q. buckleyi</i> (L. J. Dorr and K. C. Nixon 1985). A few authors have also used the name for <i>Q. gravesii</i>.</p><!--
--><p><i>Quercus</i> nuttallii E. J. Palmer var. cachensis E. J. Palmer was described as a small-fruited form (nuts 16-18 × 12-16 mm) from specimens collected in east-central Arkansas (E. J. Palmer 1937). Noting the similarity between Q. nuttallii var. cachensis and <i>Q. palustris</i>, Palmer discounted the possibility of the former being of hybrid origin because (1) he had not observed <i>Q. palustris</i> in the type locality, and (2) the leaves and buds of the former were essentially the same as in Q. nuttallii <i></i>var.<i> nuttallii</i>.</p><!--
--><p>C. H. Muller (1942), on the other hand, argued that <i>Quercus</i> nuttallii was nothing more than a form [forma nuttallii (E. J. Palmer) C. H. Muller] of <i>Q. palustris</i>. This is a puzzling conclusion because it was based largely on the premise that Q. nuttallii occurred "...with the parent species throughout a large part of the latter's southern range (Mississippi to eastern Texas and southeastern Missouri)." The range of <i>Q. palustris</i> does not extend into Mississippi or eastern Texas, although its range does overlap that of <i>Q. texana</i> in eastern Arkansas and southeastern Missouri. E. J. Palmer (1948) and D. M. Hunt (1989) have suggested hybridization with <i>Q. shumardii</i> and <i>Q. nigra</i>, respectively. See L. J. Dorr and K. C. Nixon (1985) for an explanation of the nomenclatural confusion regarding this taxon.</p>
