Explanation of the Table, Appendix, No. II. 



The two first columns, succeeding the names of plants, 

 are intended to exhibit the general range of each species 

 through certain imaginary zones of climate or latitude in 

 the N. E. of America and in Europe. These zones are the 

 Polar, Arctic, and Boreal, common to America and Europe; 

 succeeded in the former by the United States, and in the latter 

 by the Temperate and Mediterranean Zones. 



1. The Polar Zone will be understood as including all the 

 polar lands beyond 72° lat.
