This study deals with the description and illustration of morphological types identified in honeys coming from the flooded islands that integrate the Superior Delta of the Paraná River. The pollen types treated, are those that have not been previously described in melissopalynologic works or whose descriptions and/or illustrations are insufficient for its diagnostic interpretation: Bidens laevis (L.) Britton, Sterns & Poggenb, Cleome hassleriana Chodat, Eichhornia azurea (Sw.) Kunth, E. crassipes (Martius) Solms-Laubach., Eryngium divaricatum Hooker & Arnott, Gymnocoronis spilanthoides (D. Don) DC., Holocheilus hieracioides (D. Don) Cabrera, Nymphoides indica (L.) Kuntze, Plagiocheilus tanacetoides Haenke ex DC, Pontederia cordata L., and Sapium haematospermum Müll. Arg. The material was acetolized and observed with light and scanning electronic microscope. This importance of each taxon in the produccion of honeys of these areas, is remarked
