Species B. integrifolia Rich, affinis. 



Hab. Lower Guinea. Angola, Malange N'Bango thickets

 externally, not as in /i. Tysoniana Oliver. 



" A very elegant tree, 15 ft. or more high, erectly branched 

 leaflets coriaceous, glossy on both surfaces, capsule 4-valved dusl* ' 

 violet, seeds scarlet with cup-shaped aril." — J. G. ' ^ 



The position of this plant must remain somewhat doubtful imt'l 

 flowering specimens have been obtained.
