A small tree on the Bagroo River (G. Mann). 
I have some hesitation in giving a name and diagnosis to this plant, the specimen 
being insufficient to enable me to examine the internal structure of the carpels. It 
is, however, so very similar in many respects to O. gracilipes that I cannot but feel 
convinced that it is a congener, although the form of the petals does not admit of 
uniting it in the same species.

Forests at Eppah on the Niger (Barter). On the banks of the Bagroo River (G. Mann). 
The vertical septum separating the ovules and seeds is an anomaly we have not 
observed in other Anonaceae, but which both Mr. Pitch and myself have found at the 
time of flowering as well as when the fruit is further advanced.
