However, his conception and that of later workers, who often reduced it to a section, was closer to the modern section Cerris than the wider circumscription that has resulted from molecular phylogenetic studies, in which the subgenus is one of two divisions of the ...

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

Quercus subgenus Quercus is one of the two subgenera into which the genus Quercus was divided in a 2017 classification (the other being subgenus Cerris). It contains about 190 species divided among five sections .
Quercus gussonei is a species of oak native to northern Sicily. [1] It is a deciduous tree growing up to 25 meters tall. It is native to the mountains of northern Sicily from 700 to 1000 meters elevation. [2] The plant was first described as Quercus cerris var. gussonei in 1911 by Antonino Borzì. In 1984 Salvatore Brullo described it as a ...
