Steyermark (1984: 367-373) discerned several varieties and formas within Piper cernuum. With the small amount of Guianan specimens available it is impossible to distinguish different entities here.
Piper cernuum and P. obliquum are very similar morphologically. Distinguishing characters are mentioned in the note to P. obliquum.
