Dietrich's new combination is illegitimate because of the earlier Peperomia reflexa Kunth (Nov. Gen. Sp. ed. qu. 70. 1816) which is a different species.
Peperomia tetraphylla is easily recognizable by the hairy rachis of the spikes and the fruits being sunken in the rachis.
The collection of Im Thurn mentioned above, although sterile, belongs to the species. This Im Thurn collection has been mounted on one sheet with three Brazilian Glaziou collections, two of which also belong to P. tetraphylla, the third, however, to a different species.
