2.1. Utricularia adpressa Salzm. ex A.St.-Hil. & Girard , Comptes Rendus Hebdomadaires des Séances de l’Académie des Sciences 7: 870 (1838). [ Figs. 1 and 6I ].

Terrestrial or helophyte.Aerial linear leaves. Slender and flexible scape. Basifixed and free bracts and bracteoles, entire margins. Ascending pedicels in fruits. Sepals with conspicuous but non-prominent nerves, plan and entire margins. Yellow corolla, non-gibbous palate, orbicular upper lip and longer than the upper sepal, galeate lower lip, straight and acute spur, longer than and perpendicular to the lower lip. Longitudinally dehiscing capsule.

Selected material:— s.l., s.d., fl. and fr., P. Salzmann s.n. (G, K, L, MO, R original material); Belmonte , 7 km SE de Belmonte, 05 January 1981, fl. and fr., A.M. de Carvalho & J. Gatti 407 ( CEPEC, K, R); Cairu , Baixo Sul, Garapuá, 12 August 2006, fl. and fr., M.L. Guedes 13593 and 13594 ( ALCB) ; Camaçari , 30 November 2002, fl., F. Rivadavia 1455 ( SPF) ; Maraú , BR-030 entre Itacaré e Maraú, 05 November 2017, fl. and fr., F.M. Guedes 94 and 97 ( UFP) ; Salvador, Itapuã, 1951, fl. and fr., A.L. Costa s.n. ( ALCB) .

Comments:— Utricularia adpressa can be confused with U. erectiflora , U. laxa and U. nana , but it differs from U. erectiflora by its slender and flexible scape, sepals with plan margins and orbicular upper corolla lip (vs. thick and stiff scape, sepals with involute margins and oblong upper corolla lip); from U. laxa by its orbicular upper corolla lip and spur longer than the lower lip (vs. oblong upper corolla lip and spur as long as the lower lip); and from U. nana by its sepals with inconspicuous nerves, orbicular upper lip and longer than the upper sepal (vs. sepals with conspicuous nerves, oblong upper lip and shorter than the upper sepal). In the state, Utricularia adpressa has records only from areas of restinga.
