Three new species of Davilla Vandelli from Amazonas, Bahia, and Pará states, Brazil, are described and illustrated. Davilla bahiana Aymard resembles D. cuspidulata Martius but mostly differs by its leaves coriaceous, papillate on the upper surface, with lateral nerves 11 to 19, and carpels strigose at the apex. Davilla bilobata Aymard is related to D. grandifolia Moricand but can be distinguished by its tertiary nerves deeply areolate on the lower surface, inflorescence shorter (to ca. 5.5 cm), the shape and pubescence of the sepals, and the petals bilobed. Davilla neei Aymard was collected inside the study plots of the Biological Dynamics of Forest Fragments Project in central Amazonian lowland forest; it is similar to D. kunthii St. Hilaire but differs by its wider leaves (7–)15 cm long, the margins coarsely serrate, short inflorescences (only 10–11 cm long), and carpels densely hispid-incanous. Davilla bilobata is a distinctive species for its bilobed petals in a genus with otherwise predominantly entire petals.
