2.28. Utricularia resupinata B.D.Greene ex Bigelow , Florula Bostoniensis 3: 10 (1840). [ Figs. 1 and 7Q ].

Terrestrial or helophyte. Submerged/aerial cylindrical, circinate leaves. Slender and flexible scape. Basifixed tubular bracts, absent bracteoles. Ascending pedicels in fruits. Sepals with inconspicuous nerves, plan and entire margins. Lilac or white, yellow gibbous palate, reflexed trilobed lower lip (giving an aspect of resupinate flower), curved and emarginate spur, shorter than and perpendicular to the lower lip. Longitudinally dehiscing capsule.

Selected material:— Maraú, antes da entrada para Maraú, sentido Barra Grande–Maraú, 24 November 2013, fl. and fr., P.C. Baleeiro 366 ( SPF) .

Additional material:— BRAZIL. Sergipe: Estância, APA Sul , 09 March 2010, fl. and fr., I.R.N. Menezes 87 ( ASE) .

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.
