IVIozaxKXb. Distr. German East Africa: Unyika in Miwaira, 5500 ft., Ooetze, 

 1377 ! 



According to Engler's description tlie perianth-segments arc hairy on the margins, 

 but this was not found to he the case in the specimens examined. 



A specimen collected by the Rev. F. A. Rogers (8504) at Chilanga, N.W. Rhodesia, 

 is closely allied to, and may be identical with, T. unyikense, but it shows some 

 difference in its globose fruits. It is also similar to T. triste from Angola, but differs 

 particularly in the ciliate leaf-margins.
