The aim of this work was to study the pollen profile of clover and eucalyptus honeys from the Phytogeographic Pampean Province of Argentina, in order to contribute to its palynological characterization. Qualitative pollen analysis was performed. Descriptive and multivariate statistical techniques were applied to determine the frequency distribution of pollen and characterize each floral origin by pollen and year of harvest. 81 samples of honey from four different harvests were analyzed. 41 morphological types of pollen were found, which variation per sample ranged from two to eight. Eucalyptus sp. was the taxon present in over 80% of the honeys. There were pollen of Helianthus annuus and Carduus sp. in clover and eucalyptus honeys but pollen of Brassicaceae was only present in clover honeys. Pollen spectra showed differences between the studied years. [ABSTRACT FROM AUTHOR]
