the valleys, and rarely, if ever, occur within the bush, which 

 always grows on the slopes. 



The Midland Scattered Bush extends from 2000 up to 

 4000 feet, i.e. into the region whei-e the larger Yellow Wood 

 forest is found. It will be seen from the list that the Yellow 

 Wood (Podocarpus) occurs sometimes, but it is never a 

 dominant tree. It may generally be described as Comb re- 

 turn bush — C ombre tum kraussii being most abundant. 

 Most of the species extend into Tropical East Africa. Calo- 

 dendron cape use is an exception, however, and of the 

 others, Pyga?uni africanum, Celtis kraussiana and 

 Podocarpus thunbergii are mountain species in the 

 tropics. If we compare the midland with the coast type of 

 bush the latter is nearer the Tropical East African forest 

 than the former. Rhus 1 o n g i f o 1 i a, which is dominant in the 

 coast bush and associated in the midland bush, is a species 

 which is found everywhere abundantly in the tropics. 



We next come to the —
