Although Düll cites the publication of this taxon (1973: 106) as well as the type collection (1973: 107) it appears that Engler never published this variety. Bot. Jahrb. Syst. 26(1): 361 only shows Peperomia steudtii Engl. and Peperomia laeteviridis Engl. Besides, this publication was released in 1899, 5 yaers before the cited 'type' was collected [pers. comm. 2009, Mathieu]
