“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 under- 
took. Amongst these are Mr. C. B. CLarxkn, F.R.S., who worked 
out Acanthacee, and Mr. R. A. Rouirg, A.L.S., Selaginee. 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. Paiures, 
one of their staff, to come to Kew to work out Proteacee, an order 
with which he had obtained a first-hand acquaintance in the field. 
The expiration of Mr. Puituips’s leave left his task in some 
respects incomplete, and I am indebted to Dr. Srapr, F.R.S. 
Keeper of the Herbarium, and to Mr. Joun Hutcuinson, Assistant 
for Tropical Africa, for supplementing what was needed to Mr. 
PHILLIPs’s work. The laborious task of elaborating Labiate was 
undertaken simultaneously by Messrs. Brown and SKAN, and by 
r. COOKE, 
“I continue to be indebted for invaluable aid to Mr. C. H. 
Wrient, A.L.S., and to Mr. N. E. Brown, A.L.S., Assistant 
Keepers of the Herbarium, the former in reading the proofs and | 
in other ways, the latter for working out the localities and dis- 
tribution. 
“For the limits of the regions under which the localities are 
cited in which the species have been found to occur, reference may 
be made to the Preface to Volume VI. 
“ Besides the maps already cited in the Prefaces to Volumes VI. 
and VII., the following have also been used :—

“'T'o many of the South African correspondents of Kew enume- 
rated in previously published volumes I have again to tender my 
acknowledgments for the contribution of specimens in aid of the 
work to the Herbarium of the Royal Botanic Gardens. 
“| must further record my obligations to some new contributors, 
and to those whose kind assistance in various ways has been of the 
greatest value in the preparation of this section of Volume V.
