Notes

In 1866, C. de Candolle had already described Peperomia sylvestris from Ecuador (J. Bot. 4: 142).
In , P. ouabianae is given as being conspecific with P. pilicaulis C. DC. The species are rather similar but differ in indument, leaf shape and size of fruit. It seems better to keep the two species apart.
