FLORA OF EAST AND MIDDLE AFRICA 53 



alpine regions show the species to have been of quite recent 

 immigration into the region. 



The affinities of the forest flora are with West Africa 

 and to a lesser degree with Abyssinia and South Africa. 

 The flora of the nyika is distinctly East African with 

 scarcely any West or South African types, and forms a part 

 of a wide-spread association from the Red Sea to the Zam- 

 besi. The tropical coast belt is similar in affinities to the 

 nyika.
