From efloras.org Floras of North America The four species of the chestnut oak group in eastern North America (Quercus montana , Q. michauxii , Q. muhlenbergii, and Q. prinoides) are somewhat difficult to distinguish unless careful attention is paid to features of leaf vestiture and fruit and cup morphology. Attempts to identify these species mostly or solely on basis of leaf shape and dentition (as in many other oak species complexes) have resulted in a plethora of misidentified material in herbaria and erroneous reports in the literature. The closely appressed, asymmetric trichomes on the abaxial surface of the mature leaf, in combination with longer simple hairs along the midvein, are unique to Q. montana among North American species of Quercus. Immature leaves and densely shaded leaves sometimes exhibit a more erect trichome that could be confused with the longer, felty hairs of Q. michauxii, so it is important to evaluate mature sun leaves when possible.

History: 

Native to southeast Canada and the eastern US.

Cultivated since 1688.

Published in Sp. Pl., ed. 4 4(1): 440 in 1805.

From Linnaean Plant Name Typification Project (referring to Q. prinus: This name has been applied to the two species more recently known as Q. montana Willd. and Q. michauxii Nutt., and Whittemore & Nixon (in Taxon 54: 213. 2005) therefore proposed Q. prinus for rejection. This was recommended by the Committee for Vascular Plants (in Taxon 56: 591. 2007).

Some sources still show Q. montana as a synonym of Q. prinus.
