Platycaryeae Explained

Platycaryeae is a tribe of flowering plants in the family Juglandaceae, and comprising a single living genus Platycarya.^[1] The tribe is now native to eastern Asia in China, Korea, and Japan.^{[2] [3]}

A series of fossil genera have been described from the Northern Hemisphere dating between the Early Eocene,^[4] and gradually becoming confined to East Asia during the Pleistocene ice ages.^{[5] [6]} The fossil record is dominated by morphotaxa based on plant material, with isolated fruit, foliage, leaves, pollen, and woods in segregate mophogenera.
