It were analyzed 17 species subordinate to eight genera that occur in Rio de Janeiro "restingas", aiming to contribute to the pollinic characterization of this species and to the pollinic catalog of "restingas" of Rio de Janeiro. The pollen grains were acetolysed, measured, described and illustrated under light microscopy to observe details of surface, non acetolysed pollen grains were analysed under SEM. Only Byrsonima sericea has small, tricolporate and isopolar pollen grains. On other species were apolar pollen grains and presented characteristics that were used in the pollinic key. The main characteristics employed were size, number and dimension of the apertures, sexine and colpoid ornamentation. It conclude that analyzed species were palylonologically distinct and the pollinic characteristics were considered to be a good available resource to the researchers that will be able to use in the Taxonomy and in other related areas.
