Resumo: To study the palynomorphs distribution in superficial sediments and to establish the relationship between palynological data on plant taxonomy and botanical data on actual vegetationon the margin of the Patos lagoon estuary, five samples from a recent sandy silt sediments were examinated. Pollen and spores of terrestrial and aquatic plants, zygospores, colonies and coenobies of green algae (Chlorophyta), and fungal spores were identified. The pollen-and-spore assemblages recognized generally coincide with the composition of the actual vegetation in the wetland of the southern Coastal Plain of Rio Grande do Sul. The discrepancies between palynological and botanical data are probably due to different pollen productivity of plants, inequality in pollen and spores transportation capacity, and polen and spores morphological features, which are affected by the conservation in sediments.

Foram identificados pólen e esporos de plantas terrestres e aquáticas, zigósporos, colônias e cenóbios de algas verdes (Chlorophyta) e esporos de fungos. As associações de pólen e esporos reconhecidas, em geral, coincidem com composição da vegetação na Planície Costeira da parte sul do Rio Grande do Sul. Discrepâncias entre dados palinológicos e botânicos podem ser causadas por diferenças na produção polínica das plantas, pela desigualdade na capacidade de transporte de pólen e esporos e pelas características morfológicas de pólen e esporos que são influenciadas pela sua conservação nossedimentos.Iheringia.
