Abstract
ABSTRACT Peperomia is the second most diverse genus of Piperaceae, with an estimated 1,600 species and a pantropical distribution. This work aims to present a taxonomic synopsis of the genus in the State of Roraima, in the extreme north of the Brazilian Amazon forest and belonging to the central-south portion of the Guayana Shield. Based on collecting expeditions and analysis of specimens in various herbaria, 23 taxa were recognized, with two new records for the State and one of them, a new record for Brazil. The taxa are differentiated mainly by phyllotaxis, shape and size of their leaves, in addition to habit and fruits. They have been found in areas of lowland, submontane, montane, tepui and floodplain (várzea) forests and mostly show a distribution restricted to the Neotropics. Some species in the state are presently known exclusively from Mount Roraima, and restricted to a few specimens.
