Platycarya

Platycarya is a genus of flowering plants in the family Juglandaceae native to eastern Asia in China, Korea, and Japan.

The genus was formerly treated as comprising a single species Platycarya strobilacea, though the second living species Platycarya longzhouensis is now recognized.

A number of fossil species have been discovered across the Northern Hemisphere dating from the Early Eocene, although they became confined to eastern Asia during the Pleistocene ice ages.
