A botanical characterization of the Figueira pond (Upper Paraná River floodplain, in Porto Rico, State of Paraná, Brazil, at 22o45’36’’ S and 53ol5’56’’ W) has been carried out using floristic surveys and phytophysiognomic profiles, in different water periods, together with a bathymetric chart and a soil analysis. The floristic survey resulted in 36 families, 75 genera and 89 species. The families with more specific richness were Poaceae (14 species), followed by Cyperaceae and Euphorbiaceae (eight each). The highest habit incidence belonged to the herbaceous (79,78% of the species) and, concerning the biological form, there was predominance of the terrestrial (50,56%) and amphibious ones (37,08%). The phytophysiognomy, with predominance of herbaceous, shows differentiation between the banks and along the pond, with a considerable decrease of the vegetal covering in the high water periods. This pond was considered a shallow body of water, with loamy soil
