Very nearly allied to E. hispida , from which it differs in having the leaves rather 
densely tomentose beneath between the hispid nerves. The plant from Babadji, 
Cameroons, with male flowers, agrees well in this respect with Dewevre 947 from 
Nyangwe, Congo State, which is female. With Dewevre 947 in the original citation 
is associated another specimen, Dewevre 964 a, also from Nyangwe. This latter 
plant agrees as regards pubescence with E. hispida and not with E. Dewevrei , but 
it differs so markedly from both in the size and form of its leaves that it may be 
necessary, where fuller material is available, to treat it as a distinct species. Besides 
differing as regards foliage, it has a larger number of stamens than E. hispida has, or 
than the Cameroon plant which agrees as regards foliage with the female plant 
on which E. Dewevrei was based. In the meantime, it may be left in E. Dewevrei , 
where De Wildeman and Durand have placed it, but must be treated as a distinct 
variety, characterized as follows :— 
E. Dewevrei, var. inopinata. Folia secus nervos pilis patentibus hispida, 
subtus inter nervos glabra minute verrucosa, basi cuneata, 5 cm. longa. Stamina 40.

[V.] West Central Africa. Congo State; Eastern Province; 
Maniema, Nyangwe, Dewevre 964 a ! 
According to Dewevre the leaves of this variety are edible. 
An examination of this conspectus shows that in a certain number of 
instances species may be barely distinguishable as regards foliage, and 
may even closely resemble each other as regards male flowers, but may
