Annuaire Conserv. & Jard. Bot. Genève 21: 269 (1920) is sometimes cited as the publication reference for this name. That publication however is the protologue of the variety Peperomia caudulilimba var. longependula C.DC. The name Peperomia caudulilimba itself has never been published by de Candolle [Guido Mathieu, 2006, pers. comm.]
