The entries in the middle column, when there are any, are of 

 identical or representative species occurring in Oregon or California. 



Those in the right-hand column are of such species in Japan, or 

 other parts of northeastern Asia, including the Himalayas and Sibe- 

 ria as far west as the Altai Mountains. 



When these are not identical, or so closely related to the Ameri- 

 can species that the one may be said strictly to represent the other, 

 also when genera or parts of genera are adduced merely as repre- 

 senting the same type in these respective regions, the names are in- 

 cluded in parentheses. 



Species which extend through Europe into northeastern Asia, 

 and therefore nearly round the temperate zone, are also left out of 

 view, the object being to consider the peculiar relations of the floras 

 of eastern North America and eastern temperate Asia. The table 

 has been drawn up off-hand, from the means within reach. Prob- 

 ably the example might be considerably increased. 



Extra-European (Temperate) Genera and Species of the Atlantic 

 United States (i. e., east of the Mississippi) represented by iden- 

 tical or strictly representative Species, or else by less inti- 

 mately RELATED SPECIES (THE LATTER INCLUDED IN PaKENTHKSES).
