Also in Tropical Africa. 
I have not seen the type of var. angustifolia, but have reduced it, as there is a 
series of forms connecting a Natal plant (Sanderson), which corresponds closely 
with Meyer’s description, with the typical form. For a similar reason I have 
not kept up Hiern’s var. vaga which is also represented by a Natal specimen 
(Hewitson). 
Native names (Zulu) ‘f um-Quaquane,”’ ‘‘ um-Quaqongo”; some parts of the 
tree are used as a purgative for calves (Wood, 1.c.).
