The species of this genus (Capparidacez) are shrubs or small 
trees occurring in the tropical and sub-tropical regions of 
Northern, Central, and Southern Africa. The author recognises 
27 species, several of them being established by himself. The 
most important part of the work is devoted to the histology of 
the plants. The results are highly interesting, as the structure 
of the leaves of those species which grow in dry regions like the 
Kalihari, Griqualand West, and the Western Transvaal possess 
very elaborate means of protection against drought, the 
mechanical part of the tissues being specially well developed. 
This investigation also shows that the anatomical characters of 
plants are often very useful in determining the identity or non- 
identity of species.
