THE NATURAL IIISTOEY EEYIEW. 



Tropical Africa, according to the data published twenty years 

 ago, in tne Niger Flora, differs little in its ten dominant Orders, 

 and their sequence fromr Ceylon ; and lastly, to show that this 

 uniformity is not accidental, we have taken the figures from Miquel's 

 riora of the Dutch East Indian Islands, which also includes a good 

 many Continental Asiatic plants. 



•Again, of the 110 Orders, common to Ceylon and the British 

 "West Indies, only 37 are so unequally represented as to contain in 

 one country double the number of species which the other contains. 

 They are the following : —
