The Quercus Rubra is commonly known as the Common Red Oak, Eastern Red Oak, Gray Oak, Mountain Red Oak, Northern Red Oak as well as Red Oak.
Northern red oak is a member of the red oak-black oak subgenus (Erythrobalanus) within the order Fagales . The currently accepted scientific name of northern red oak is Quercus rubra L. . The epithet Q. rubra was formerly applied to several species of oak including the southern red oak (Q. falcata) . Some later taxonomists rejected the appellation Q. rubra because of past ambiguity and in 1915 identified northern red oak as Q. borealis . In 1950, the name Q. rubra was restored . Most current authorities prefer the epithet Q. rubra, although Q. borealis is still occasionally encountered in the literature. The following varieties are commonly recognized : Quercus rubra var. borealis (Michx. f.) Farw.
