The objective of the present study was to survey the species of Calycorectes O. Berg, Hexachlamys O. Berg, Myrcianthes O. Berg, Myrciaria O. Berg and Plinia L. in the Upper Paraná River floodplain, located in Mato Grosso do Sul and Paraná states (22º40’ to 22º55’S and 53º10’ to 53º40’W), Brazil. The study area, under domain of the Submontane Semidecidual Seasonal Forest, include riparian formations of the Paraná River and its islands and tributaries. The species registered were Calycorectes psidiiflorus (O. Berg) Sobral, Hexachlamys edulis (O. Berg) Kausel & D. Legrand, Myrcianthes pungens (O. Berg) D. Legrand, Myrciaria delicatula (DC.) O. Berg, M. cuspidata O. Berg, Plinia rivularis (Cambess.) Rotman and P. trunciflora (O. Berg) Kausel. The months of major flowering and fructification were, respectively, September and November 2000 and 2001. Calycorectes psidiiflorus has the largest distribution in the study area, and Myrcianthes pungens the more limited, exclusively on the left banks of the Paraná River, and its tributary, the São Pedro Stream. For each species illustrations, descriptions, and identification keys are given.
