492 DR. OTTO STAPF ON 
To this species are to be referred with some reserve a specimen 
collected by G. Mann in the island of Fernando Po (no. 3), and 
one, colleeted by Dinklage, on the ground of moist shady forests 
near Gross-Batanga, Cameroons (no. 851). Both agree perfectly 
with Barter's specimens with the exception of the leaves, which 
are rather broader and have more numerous, closer, and more 
projecting transverse veins. One of the leaves of Mann 
specimens measures 22 by 17 em. and is cordate at the base. It 
is possible that these two specimens represent a distinct species.
