Eastern Asiatic Region

The Eastern Asiatic Region (also known as Oriasiaticum, Sino-Japanese Region, East Asian Region, Temperate Eastern Region) is the richest floristic region within the Holarctic Kingdom and situated in temperate East Asia. It has been recognized as a natural floristic area since 1872 August Grisebach's volume Die Vegetation der Erde and later delineated by such geobotanists as Ludwig Diels, Adolf Engler (as Temperate Eastern region), Ronald Good (as Sino-Japanese Region) and Armen Takhtajan.
