- Safford has 1ecently pointed out that Unona discreta is a 
Xylopia, and that the Asiatic species hitherto included in Unona 
should be referred to Desmos.* Other authors consider that the 
section Dasymaschalon should be treated as a distinct genus.t 
As stated under Orymitra, four of the five African species of 
Unona recognised by Engler and Dielst should be referred to 
Oxymitra. The remaining one, U. Stuhlmannii, Engl., seems 
to approach some of the species referred to Popowia by Engler, 
and Diels. We have not seen a specimen. 
which Engler and Diels seem to attach no importance, the charac- 
ters of the gynoecium are sufficient to distinguish Asimina from 
Uvaria, as may be seen by comparison of the figures of Asimina 
given by Sargent|| and He 7 y 
King** and Engler and Diels.t+ As to Porcelia and Sapranthus, 
the investigations of R. E. Fries have shown that these two
