Camus : n° 385; – Sub-genus Quercus, section Lobatae, Series Erythromexicanae, Group Acutifoliae; – For today’s Mexican Authors (Silvia Romero Rangel 2006), as for Govaerts 2013 (The Plant List), this species is a synonym of Q.xalapensis; actually it is a different species, xalapensis having wider leaves, larger bristle-tipped teeth, and an acorn maturing in 2 years; – Very similar to Q. furfuracea , if not identical ?? – Possible confusion with Q. paxtalensis , which has leaves more shiny, longer aristate teeth, and a cup turbinate. – Q. sartorii Botteri ex A.DC is a synonym of Q. grahamii
