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. †Platycarya americana Hickey †Platycarya bognorensis (Chandler) Wing & Hickey †Platycarya castaneopsis (Lesquereux) Wing & Hickey †Platycarya manchesterii Wing & Hickey †Platycarya miocenica Hu & Chaney †Platycarya pseudobrauni (Hollick) Wolfe †Platycarya richardsoni (sic P. richardsonii) (Bowerbank) Chandler...read more on Wikipedia.
