The genus Quercus contains about 500 known species, plus about 180 hybrids between them. [1] The genus, as is the case with many large genera , is divided into subgenera and sections . Traditionally, the genus Quercus was divided into the two subgenera Cyclobalanopsis , the ring-cupped oaks, and Quercus , which included all the other sections.

Like all species of Quercus, those of subgenus Cerris are trees or shrubs with acorn-like fruit in which a cup covers at least the base of the nut.Members of subgenus Cerris are distinguished from members of subgenus Quercus by few morphological features, their separation being largely determined by molecular phylogenetic evidence.
