Peperomia tubericordata (Piperaceae), a new geophytic species from Oaxaca, Mexico

Abstract

A new Peperomia species from the state of Oaxaca, Mexico is described and illustrated. It shows the typical morphological characters of subgenus Tildenia (presence of an underground tuber and leaves and inflorescences directly originating from that tuber), but differs from all other members of that subgenus by the orbicular to reniform, cordate, non-peltate leaves.
