A. Camus : n° 401;
-- Sub-genus Quercus, section Lobatae, Series Erythromexicanae, Group Acutifoliae;
-- Hybridizes with Q.salicifolia in Costa-Rica, and with Q.benthamii in Honduras;
-- Closely related to Q.sartorii Liebm., species considered as a synonym of Q.xalapensis by S.Romero Rangel 2006, though xalapensis has acorns maturing in 2 years;
-- Q. brenesii is often considered as a true species, although closely related (See the Taxonomical revision of Acutifoliae by S. Romero Rangel), differing from Q.cortesii in having fewer secondary veins (7 to 11, showing a "s" shape before entering the teeth) and divergent teeth; also Q. brenesii has a yellowish green colour of the upper side of the blade, with possible amber glandular trichomes.
