Dr. Cuatrecasas writes: ‘‘Paraprotium amazonicum is 
closely related to P. vestitum Cuatr., from the Pacific 
Coast of Colombia. It differs from it by its leaves having 
more numerous oblong, narrower leaflets which are mi- 
nutely puberulent and more prominently reticulate 
beneath. Furthermore, Paraprotium amazonicum has 
smaller and more zygomorphous fruits and more acute 
pyrenes. ”’
