This species is closely related to the species of eastern America and of Europe, and 

 it needs further investigation to decide whether these three trees are to be treated 

 as subspecies or as distinct species. So far as I can see without having carefully 

 studied all the specimens from America and Europe, the Asiatic species seems to be 

 somewhat intermediate between them.
