72a. E. Dompeyanum DC. Prod. v. 167 (1836). It seems by no 
means improbable that this species (discussed in some detail on page 
11) was originally collected in Peru. It reached DeCandolle devoid 
of data beyond the fact that it had been gathered in South America 
by Dombey (DC., phot. Gr.), whose explorations were chiefly in 
Peru. .

abundant on the inflorescence; leaves opposite, ovate, acute or slightly 
acuminate, mucronulate-serrate or -crenate (the teeth inconspicu-
