|discussion=<p>This widespread species of Mexico and Central America has only recently been discovered in the United States as a small grove of trees about 30 km from the international border in Texas (B. J. Simpson et al. 1992). Quercus polymorpha is becoming available in the nursery trade in Texas and the southeastern United States. It is distinct from the superficially similar Q. splendens Née (= Q. sororia Liebmann) of western Mexico, with which it is sometimes placed in synonymy, in that Q. splendens has connate cotyledons instead of distinct cotyledons, as in Q. polymorpha.</p>
