PREFACE, vii 
Cape Colony and Liideritzbucht in Great Namaqualand in the 
summer of 1908-9, and a second expedition under the same 
auspices, between Eendekuil in Cape Colony and Sendling’s 
(or Bethany) Drift in the Orange River in the summer of 
1910-11. The summer flora of the greater part of these 
regions was previously little known, and the material collected 
in Bushmanland and the eastern part of Great Namaqualand 
in the former journey and in the Richtersveld (between 
Ookiep and the Orange River) in 1910-11, furnishes many 
new records of distribution and contains a considerable number 
of new species. 
The Natal Government has made no contribution to the 
work since 1907. On the other hand that of the Transvaal 
has given spontaneously a liberal grant, and this has been 
followed by a still more substantial one which it is hoped 
will provide sufficiently for the completion of the work. 
In the present section I have been again fortunate in securing 
the aid of contributors who in many cases were able to bring 
to bear the advantage of previous study on the groups they 
undertook. Amongst these are Mr. C. B. CharkE, F.R.S., who 
worked out Acanthacex, and Mr. R. A. Ror, A.L.S., Selaginex, 
I have had the further advantage of the continued co-operation 
of South African botanists. Professor PEARSON has contributed 
Verbenacee, and I am indebted to the Trustees of the South 
African Museum for granting leave of absence to Mr. E. P, 
Pures, one of their staff, to come to Kew to work out 
Proteacex, an order with which he had obtained a first-hand 
acquaintance in the field. The expiration of Mr. PHILLIPs’s 
leave left his task in some respects incomplete, and I am 
indebted to Dr. Starr, F.R.S., Keeper of the Herbarium, and 
to Mr. Jonn HvTcHINSoN, Assistant for Tropical Africa, for 
supplementing what was needed to Mr. PHILuips’s work, 
The laborious task of elaborating Labiate was undertaken 
simultaneously by Messrs. BRowN and SKay, and by Dr, 
COOKE. pill 4 [ . 
I continue to be indebted for invaluable aid to Mr. C. H. 
Wnricut, A.LS., and to! Mr, N. E. Brown, ALLS., Assistant
