At the present date there are 173 species of Ficus known 

 from Tropical Africa, almost all of them being endemic. A key 

 to these, with full descriptions of each species, will appear in 

 the forthcoming parts of the Flora of Tropical Africa. The fol- 



notes are intended to show the general treatment of the 

 species in that work as compared with the German revision. In 

 the latter the species were arranged under 5 subgenera, as fol-

6 species, and the remaining 73 species, under a new subgenus 

 termed the Bibracteatae, the members of w^hich were included 



in Urostigma by M 



The present paper deals chiefly with 



the last subgenus, as Mildbraed and Burret's arrangement of the 

 other four subgenera has been mainly followed, with the addi- 

 tion of a few new species (here described) and the revival of 

 such as appeared to me to have been erroneously reduced. For 

 these alterations the reader is referred to the forthcoming parts 

 of the Flora already mentioned. 



Mildbraed and Burret applied the name Uihracteatae to a large 

 group of plants which were described as having two bracts at 

 the base of the receptacle. But in the majority of the species 



of this group the basal bracts are very early caducous, and leave
