Notes

I agree with Trelease and Yuncker (1950: 410) that Piper warakabacoura and P. bartlingianum are conspecific. The differences used to separate the two, for instance by De Candolle, are on leaf size and shape and a few hairs on the fruits. With the large amount of collections studied, it can be concluded that the variation is such that it is not possible to maintain two species.
