Abstract

Placing Peperomia berteroana of the Juan Fernandez Islands in the Pacific Ocean in synonymy with P. tristanensis of Tristan da Cunha in the Atlantic Ocean results in a species with a wide geographical disjunction of more than 5000 km. Morphological data indicate that these taxa are best treated as subspecies (P. berteroana subsp. berteroana and P. berteroana subsp. tristanensis).
