Comments:— Utricularia flaccida can be confused with U. nervosa , but it differs by its lithophytic life form, sepals with non-prominent nerves and corolla with truncate spur, shorter than the lower lip (vs. terrestrial or helophytic life form, sepals with prominent nerves and corolla with subulate/bifid/quadrifid spur, longer than the lower lip). This species is endemic to northeastern Brazil; besides the campos rupestres of Bahia, it is also found in Montane Dense Ombrophilous Forest in Ceará state and ecotones between Dense Ombrophilous Forest and Submontane Seasonal Decidual Forest in Sergipe state ( Guedes & Alves 2020) .
