This type of bush extends up to tlie edge of the first- 

 terrace, i. e. to about 1500 feet. It grows on the south- 

 eastern slopes, facing the rain clouds, and sheltered from the 

 dry hot winds. Most of the species composing it extend 

 through Tropical East Africa. The trees possess a notably 

 tliick bark. Al])izzia fasti giata and Rhus Ion gi folia 

 are the two dominant trees. Albizzia has the umbrella- 

 form, a clear bole and a widely expanded flat crown, a form 

 which is characteristic of the trees composing the drier Thorn 

 Savannah. Sclerocarya is also often flat-topped, but Rhus 

 longif olia and the others, both sub-dominant and associated, 

 are more rovmded in form.
