2.13. Utricularia jamesoniana Oliv. , Journal of the Proceedings of the Linnean Society, Botany 4: 169 (1860). [ Figs. 1 and 6W ].

Epiphyte. Stolons with tubers. Aerial obovate leaves. Slender and flexible scape. Basifixed and basally connate bracts and bracteoles, entire margins. Ascending pedicels in fruits. Sepals with conspicuous but non-prominent nerves, plan and entire margins. White corolla, sometimes with lips and spur apex tinged in lilac, yellow non-gibbous palate, deeply trilobed lower lip, curved upwards and subulate spur, 3-5 times longer than and perpendicular to the lower lip. Longitudinally dehiscing capsule.

Selected material:— Arataca , PARNA Serra das Lontras, Serra do Peito de Moça, 17 December 2005, fl. and fr., J.G. Jardim 4908 ( CEPEC); Camacã, RPPN Serra Bonita, 26 July 2007, fl. and fr., A.M. Amorim 6980 ( CEPEC) .

Comments:— Utricularia jamesoniana can be readily distinguished from any congeners in Bahia state by its epiphytic life form, stolons with tubers and white corolla, sometimes with lips and spur apex tinged in lilac, and curved upwards spur, 3-5 times longer than the lower lip. This species is represented in the state by only two records in areas of Montane Dense Ombrophilous Forest .
