extent, but apparently not so strongly as the small variety (B. Swinnyr 
E.P.P.). The latter always has it and usually very strong. 
The results of my investigation may be summarized as follows :— 
1. Foresters had hitherto only recognized two species, viz., B. lucens and B. tysoniana. 
2. Under the name of B. tysoniana, three species have been included— 
(a) B. tysoniana, found in both the mountain and coast forests. 
(b) B. Swinnyi, found only in the coast forests. 
(c) B. Stayneri, only recorded from Natal. 
3. The bark of B. tysoniana, B. Swinnyi, and B. Stayneri is used medicinally by | 
the natives. 
4. The bark of B. Swinnyi has a bitter burning taste and differs in this respect 
from that of B. tysoniana and B. Stayneri, in which the bark, while bitter, has 
not the burning taste. 
. There appear to be two forms of B. Swinnyi in the forest of Port St. Johns, 
known to the foresters as the large and small varieties. The natives are said 
also to distinguish these, but have the same name for both. 
I have been unable to furnish any additional information with regard to the other 
species recorded. 
In conclusion I should like to refer again to Mr. C. C. Robertson’s share of this work. 
Since 1914 he has been slowly accumulating evidence from foresters about the species, 
and my remarks are only a digest of the information he collected. 
With the assistance of the Forest Department, the Division of Botany is undertaking 
an examination of the barks of the various species as regards their medicinal value.
