Gymnosperms include vascular plants with seeds not enclosed within fruits. Recent molecular studies support the monophyly of extant Gymnosperms. It comprises a group of species widely used for economic and ornamental purposes. Nevertheless, there are a few studies on this group in Brazil. In the present study we carried out a survey of the species and counted specimens occurring in Ibirapuera Park, São Paulo, São Paulo State, Brazil. An identification key to the species of the Park and descriptions for each species were prepared. We recorded 20 species of Gymnosperms in the park, belonging to 13 genera in five families and registered 352 individuals spread over 35 sectors of the park. Ibirapuera Park showed the highest number of species of Gymnosperms, in comparison with other surveys in the municipality, in addition to presenting six species as the first recorded occurrence, demonstrating the importance of this site for conservation.
