PREFACE, 
THe seventh volume of the Flora of Tropical Africa was completed in 
1898. The circumstances under which the work was resumed are stated 
in the preface. 
The choice of the next instalment to be taken up was mainly 
determined by the assistance I was able to secure from contributors. 
Amongst these I am more especially indebted to my friend Mr. C. B, 
Clarke, F.R.S., who not merely undertook the difficult task of elabora- 
ting the Acanthacew, which occupy half the volume, but made a journey 
to Berlin to study the material preserved in the herbarium of the Royal 
Botanic Museum. 
For the amended definition of the regions into which the area of the 
flora is divided reference may be made to the preface to the seventh 
volume. 
In the prefaces to the first and seventh volumes will be found an 
enumeration of the materials employed up to 1868 and of the most 
important additions to them which have reached Kew since. The only 
further collections at Kew cited in the present volume are :— 
III. Nive Lanp. J. Theodore Bent. Collection from the coast 
region of Nubia in 1895-6. (Died 1897.) 
IV. Lower Guinea. Dr. Ch. Bommer, Brussels. A collection of 
Lindner’s Damaraland plants. 
VI. Mozampique. Professor C. Fritsch, Graz. A collection made 
in the Zambesi Valley at Boruma by Father L. Menyharth,S.J. (Died

The present volume was ready for the press at the beginning of
