Flora of the Leribe Plateau and Environs. 31 



advisable to treat the subject in a separate paper, and for comparison 

 with our Region I will only use the " Kaffrarian " flora and the flora 

 of Natal under 4000 ft., above which it assumes a totally different 

 aspect.

The five predominant Orders are the same in each case, the Eastern 

 Mountain Region differs from the other two floral areas in the 

 important position taken by the grasses and the comparatively few 

 Leguminosae. The Compositae also form a far larger percentage of 

 the total flora than in either the Kaffrarian or Natal areas. It is oulv

when the floras are examined more critically that the marked differ- 

 ence between the Eastern Mountain and the South-Eastern Regions 

 becomes apparent, as the following table shows :
