2.5. Utricularia costata P.Taylor, Kew Bulletin 41: 7 (1986). [ Figs. 1 and 6O ].

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 and prominent nerves, entire margins, lower sepal becomes navicular in fruits. Lilac corolla, white and yellow gibbous palate, shallowly trilobed lower lip, straight and obtuse spur, longer than and parallel to the lower lip. Longitudinally dehiscing capsule.

Selected material:— Serrinha , Próximo à Torre da Embratel, Povoado Barra do Vento, 18 August 2006, fl. and fr., L.P. de Queiroz 12292 ( HUEFS) .

Comments:— Utricularia costata can be confused with U. rostrata , but it differs by its sepals with prominent nerves, upper sepal with non-rostrate apex, lower sepal becomes navicular in fruits, shallowly trilobed lower lip, straight spur, twice as long as the lower lip (vs. sepals with non-prominent nerves, upper sepal with rostrate apex, lower sepal does not become navicular in fruits, trapezoid and crenate lower lip, curved spur, shorter than or as long as the lower lip). In Bahia state, this species is represented by only one record, in an area of Submontane Seasonal Deciduous Forest .
