Obs. Since I first described this tree, and only from plants — 
that were completely hermaphrodite I have found some plants

_From the sensible qualities of the green parts of this plant, 
being somewhat foetid, and simply, though intensely bitter, it 
‘promises to be as good an antedystenerical medicine as 
Bruce’s Abyssinian Wooginos itself. As soon as the plants 
arrive at greater maturity the bark shall be tried, and com- 
pared with Angustura bark which has by some been thought 
that of Brucea antedysenterica of Bruce’s Travels, &c. vol. v.
