Portugués. Knowledge of the flora that bees visit is important for characterization of their products and conservation of flora and fauna. Thus, this study identified the flora used by Apis mellifera L. (Hymenoptera: Apidae) during the honey production period through the pollen spectrum. Honey samples were collected at apiaries in the municipality of Cruz das Almas, Bahia, Brazil. International methods for samples preparation were used. ETOH was use for honey dilution and subsequently subjected to acidic treatment by the standard method of acetolysis. The pollen content resulting from the analysis was examined under an optical microscope, with separation and counting of pollen grains. Pollen types were identified by consultation and comparison to reference pollen collections and specialized literature. Twenty-seven pollen types distributed among 19 botanical families were identified in the sample set, and Fabaceae, Rubiaceae, Asteraceae and Sapindaceae were the families with a greater number of pollen types. The most frequent pollen types were Mimosa tenuiflora, Vernonia condensata, Bidens, Hyptis, Amaranthus spinosus, Schefflera morototoni and Serjania pernambucensis, all with relative frequency in samples equal to or greater than 70%. The honey evaluated showed a diverse pollen spectrum, evidencing multifloral characteristic.
