Africa were class^ified by the writer in 29 sections.* The South 

 African species have been arranged in a similar way in the forth- 

 coming part of Dyer, Flora Capensis, vol. v. sect. 2, but owing 

 to the relatively ■ small number of species concerned, it seemed 

 inadvisable to introduce the names of the sections into the key. 

 In order to facilitate comparison with the classification adopted 

 in The Flora of Tropical Africa, a key and 

 South African sections are now given.
