Flowering Plants and Ferns oj the Cape Peninsula. 225 



that of the latter have been mentioned in the foregoing pages. It 

 must suffice now to show both certain resemblances as well as 

 differences by a tabulated list of the chief constituents of each. 



For a comparison of mere richness of species in proportion to 

 area it must be remembered that the enumerations following afford 

 little aid. Natal has an area of 21,150 square miles, or very nearly 

 the size of the island of Tasmania ; while, as before stated, the Cape 

 Peninsula has but 197. We can therefore use them as an aid to 

 comparison of the constituent elements of the Flora of each of two 

 neighbouring Eegions only ; and from that point of view they possess, 

 incomplete as they are, considerable interest. Natal is very much 

 less fully explored than the Cape Peninsula, a large part being 

 mountainous and difficult of access, and large additions to the 

 records of the Flora may be expected for many years to come. 



Mr. Wood's Catalogue, after deduction of Cryptogams, varieties 

 and introduced species, shows a total of Orders, 123 ; genera, 756 ; 

 species, 2,360. Of these, there are 38 Orders and 460 genera 

 which have not been found on the Cape Peninsula ; while there 

 are 6 Orders and 195 genera belonging to the latter which are 

 not in Mr. Wood's list. 



The following is a list of the larger Orders of each Flora arranged 

 according to the number of species, to which have been added for 

 convenience' sake the chief twelve Orders of the Karoo Eegion 

 which will be mentioned presently : —
