It has been found necessary to revise the generic limits of 
Cleistopholis, Unona and Uvaria as extended by Engler and 
Diels, and to transfer several species from them to Oxymitra 
and Uvariastrum.. These transferences are discussed under the 
genera in question. A few new species are also described. In 
order to facilitate reference, the genera dealt with are arranged 
aipkabedidalty.
