Comparing this list with that given by Bolus for the South- 

 West Region generally, it is found that the first three orders, 

 Compositae, Ericaccce, and Leguminosae, occupy the same relative 

 positions in importance ; the grasses are better represented, while 

 the Liliaceae are but poorly represented. Too much stress must 

 not be laid on this comparison, as the area under consideration is 

 but a small portion of that dealt with by Bolus. We will only be 

 able to tell whether the mountain flora differs in com])Osition from 

 the flora of lower levels when the highland and lowland floras of 

 several localities have been thoroughly explored and worked up. 



The most important results obtained, ])erhaps, are those 

 relating to the character of the vegetation existing under mountain 

 conditions, and in this I have followed the classification of 

 Raunkiaer, as outlined by Bews, in his paper on " The Vegeta- 

 tion of Natal." The results are as follows : —
