This pollen catalogue aims at helping the study of paleoenvironmental reconstructions by palynology of sediments in southern Brazil Plateau. It presents gymnosperms and angiosperms pollen found in a sedimentary profile from a bog of Rio Grande do Sul Eastern Plateau. The profile has 286 cm long, corresponding approximately to the last 25,000 years. The 22 samples were collected in regular intervals in the profile, chemically treated following the standard method and analyzed by light microscopy. Pollen grains from two gymnosperms and 43 angiosperms (one Magnoliidae, five Hamamelidae, six Caryophyllidae, six Dillenidae and 25 Rosidae) are presented. The pollen material is described and illustrated. The descriptions are accompanied, whenever possible, by ecological data of the original sporophyte.
