Abstract
This study presents the floristic treatment for the species of Vitaceae occurring in the Reserva Florestal Adolpho Ducke, Amazonas, Brazil. Collections from the Reserva Ducke were analyzed from specimens deposited at the INPA herbarium. Two species of the genus Cissus were recorded, Cissus erosa and C. verticillata subsp. verticillata. We present species descriptions, taxonomic comments, illustrations, habitat information, geographic distribution, and an identification key for the species.
