It is native to south-central and southeast China,[1] in particular the provinces of Anhui, Fujian, Guangxi, Hubei, Hunan, Jiangxi, Shaanxi, and Sichuan.[2] It has incorrectly been known as Quercus multinervis, which is properly the name of a fossil species.[1] It is placed in subgenus Cerris, section Cyclobalanopsis.[3]

Taxonomy

Quercus hypargyrea was first described as Quercus glauca var. hypargyrea in 1900 by Ludwig Diels, who attributed the name to Karl Otto von Seemen. It was raised to a full species in 1992.[4] Independently, the species was described as Cyclobalanopsis multinervis in 1963. In 1998, this was transferred to Quercus as "Quercus multinervis". However, this name had already been published in 1859 for a fossil species, so is illegitimate.[5][1]

It is placed in subgenus Cerris, section Cyclobalanopsis.[6]
