Pink corolla, yellow gibbous palate, bilobed lower lip, straight and obtuse spur, shorter than and parallel to the lower lip. Circumscissile capsule.

Selected material:— s.l., 1830, fl. and fr., P. Salzmann 449 (G original material of U. salzmanii ); Conde , Ilha das Ostras, 03 November 2001, fl. and fr., D.L. Santana 648 ( ALCB) ; Cruz das Almas, Açude do Instituto Agronômico do Leste , 20 February 1956, fl. and fr., G. Pinto 56-25 ( ALCB) ; Maraú , Lago em propriedade particular, 12 January 2008, fl. and fr., C.S.D. Souza 230 ( CEPEC) ; Valença , 08 October 2005, fl. and fr., F. Rivadavia 2107 ( SPF) .

Comments:— Utricularia hydrocarpa can be confused with U. foliosa (see comments section in this species) and U. poconensis , but it differs from U. poconensis by its pink corolla and presence of a cleistogamous flower at the base of the scape (vs. white to pale pink corolla and absence of cleistogamous flowers). In the state, this species is found only in areas of restinga.
