VII. Korea (33°-43°N.Lat., 124°-131°E.Long.) 



As may be inferred from the geographical relation existing be- 

 tween the continent and the peninsula on the one hand and between 

 the latter and Japan on the other, the flora of the northern part 

 (38"'-43°N.Lat.) of the peninsula bears a great resemblance to that 

 of the eastern Asiatic continent, while the flora of the southern part 

 has a close connection with that of the western part of the Main 

 Island of Japan.
