Pollen was analyzed from two samples of honey from two places in the Valley of Mexico. After being acetolyzed, the samples were observed using light microscopy. Nineteen pollen types were found, belonging to 15 plant families, although the really important sources were: Brassica sp., Eucalyptus sp., Asteraceae and Lopezia sp. Some of the pollen grains found in the honey samples were from nectariferous plants: Eucalyptus, Salvia, Ipomoea, Lopezia, Pseudobombax, papilionoid legumes, Euphorbiaceae and Rubiaceae; one species that produces pollen only: Zea mays; and plants both nectariferous and polleniferous: Brassica, Schinus molle, Asteraceae and Cucurbitaceae. The family represented by the greatest number of species was Leguminosae. The foraging behavior of Apis mellifera L. can be classified as polylectic.
