Notes

In the non-Guyanan Peperomia lancifolia Hook. subsp. erasmiiformis (Trel.) Steyerm., the inflorescence is paniculate.
The collection Maguire 46076A had been misidentified as P. pyramidata Sodiro, the specimen fits well within P. lancifolia having a once-branched panicle, not a compound one as in P. pyramidata from Ecuador.
In the Guianas only: subsp. lancifolia.
