﻿PREFACE. 



On the completion of Volume VII., it was intended to take 

 up the work with Volume IV. at the point at which it had 

 been left by Professor Harvey and Dr. Sonder. It was 

 found, however, that owing to the large increase of material, 

 it would be necessary to divide the volume into two sections. 

 Unforeseen but unavoidable difficulties arose in dealing with 

 the first section, the preparation of which, however, is now 

 far advanced. In the meantime it seemed unadvisable to 

 delay the publication of the second section, which is now 

 completed. 



The smaller orders have been worked out by members of 

 the Kew staff past and present. 



For the Scrnpliulariacese, so extensively represented in South 

 Africa, I am indebted to W. P. Hiern, Esq., F.E.S. 



For the limits of the regions under which the localities in 

 which the species have been found to occur are cited, reference 

 may be made to the preface to Volume VI. 



I have again to acknowledge the assistance I have received 

 from Mr. C. H. "Wright, A.L.S., and Mr. N. E. Brown, 

 A.L.S., Assistants in the Herbarium of the Royal Botanic 

 Gardens — the former in reading the proofs, and the latter in 

 working out the geographical distribution. 



Besides the maps already cited in the prefaces to Volumes 

 VI. and VII., the following have also been used : — 



Map of the Colony of the Cape of Good Hope and neigh- 

 bouring territories. Compiled from the best available infor- 

 mation. By John Templer Horne, Surveyor-General, 1895. 

 Stanford's new map of the Orange Free State and the 

 southern part of the South African Republic, &c. 1899.
