Comments:— Utricularia resupinata can be readily distinguished from all the other congeners in Bahia state by its tubular bracts and lilac or white corolla with reflexed trilobed lower lip, which gives an aspect of resupinate flower. This species is represented by only one record in the state, which is the southernmost known population of the species.
