The difficulty coilectors experience in obtaining flowering and 
fruiting specimens of the trees of the Tropical African Evergreen 
Forest is well seen in the fragmentary material by which most 
of the Anonaceae are known even at the present time. Where 
the flowers are unisexual and especially when the trees are 
dioecious, it is not advisable to consider material collected at 
different times and in different places as representing the corre- 
sponding sexes of the same species abet de when there are 
differences in the vegetative organs and indumentum. 
In the following case material with male aware collected by 
Mann in 1861 on the Gabon River (No. 960) and the material. 
with female flowers collected by him on Mount John, Kongui 
River, Cameroons (No. 1782) was treated by Oliver in the Flora 
of Tropical Africa Vol. I. p. 23 as being opposite sexes of the
