Not to be considered as synonym of Peperomia marmorata Hook. f. as was published by Yuncker, 1974.
Although in general P. verschaffeltii has elliptic leaves with an obtuse to rounded apex and P. marmorata has ovate leaves with an acuminate apex, it might be difficult to distinguish both species solely by the leaf shape because there may be some variation in the apex. In addition both species show a similar variegation pattern of white zones between the main nerves. When it comes to the inflorescences however there is a distinct difference. Peperomia marmorata has slender spadices, up to 20 cm long and not more than 0.5 cm in diameter. Peperomia verschaffeltii has quite distinct cigar shaped spadices, up to 10 cm long and up to 2 cm in diameter. The mentioned differences are well illustrated by the iconotypes of both species [Mathieu & Callejas, 2006: 349]
