The purpose of this research was to characterize the flowering phenological phases and to determine the flower visitors in a natural population of Drimys granadensis (common name: canelo; Winteraceae) in Altos de Yerbabuena, eastern mountains of Sabana de Bogotá ( Colombia ). Floral phenology development lasted 9.5 days when flowering occurred under sunny conditions, 12.5 days under rainy conditions and 16 days when flower visitors were excluded using cloth bags. It was done observations related with the resources used, the phenological phases of visited flowers and the pollen load on the flower visitors. Visitors corresponded with 29 morphospecies, 6 orders y 21 families of insects. Four species of coleoptera and two species of diptera were considered as possible pollinators taking in account abundance and pollen load. The results are analyzed in relation with those reported for other species in the genus Drimys and in the family Winteraceae.

Palabras clave : Flora phenology; flower visitors; pollinators; pollen load; Drimys granadensis.
