The Yucatan Peninsula, located in southern Mexico, is a central honey-producing region with extraordinary biodiversity of melliferous plants. Approximately 900 plant species have been described as being a source of nectar and pollen for bees and other pollinators. They provide ecosystem services that help to keep plant biodiversity high and mitigate the effects of climate change. This study aimed to reveal the diversity of the pollen content in honey through a melissopalynological analysis of 22 honey samples collected in February–August 2021 from the north-central area of Campeche, Mexico. The extraction of pollen from the honey was carried out using standard methods for melissopalynological analysis. The honeys were classified by botanical origin to determine their floral sources and a diverse spectrum of 19 pollen types from 13 families was identified. Only eight were predominant: Milleria quinqueflora, Gymnopodium floribundum, Terminalia buceras, Amaranthus spinosus, Zea mays, Talisia floresii, Guazuma ulmifolia, and Croton icche. Our research shows the high quality of the honey analyzed and highlights the diversity and critical role of local melliferous flora and crops in beekeeping development in southern Mexico. The results in this study are useful for confirming the botanical origins of honey, generating information for designing nature conservation and agroecosystem management strategies, and increasing the knowledge of beekeepers in Campeche, Mexico.
