might have included the degradation of lofty mountains. 



It Avould also be accompanied by a lowering of some of the 

 existing area. This would modify the climate in various 

 ways, leading probably to a higher temperature and more 

 moisture, thus giving more favourable conditions generally 

 for a great variety of plants. 



For easy reference it may be well to give here a table 

 showing the main facts as to these warm-temperate floras.

Temperate Floras of Smaller Areas compared 



We will now deal with a series of smaller areas (com- 

 parable to our counties) which I have been able to collect 

 from various parts of the world ; and I propose to arrange 

 them in order of latitude, from north to south, so as to show 

 still more distinctly the influence of climate. Each main
