1.7. Genlisea tuberosa Rivadavia, Gonella & A.Fleischm. , Systematic Botany 38: 464 (2013). [ Figs. 1 and 6G ].

Terrestrial or helophyte. Stolons with tubers. Scape, bracts, bracteoles and sepals covered with eglandular and long-stalked glandular trichomes. Slender and flexible scape. Ascending pedicels in fruits. Yellow corolla, gibbous palate, glabrous lips, shallowly trilobed lower lip, glandular and acute spur, longer than and parallel to the lower lip. Circumscissile capsule, covered with eglandular and glandular trichomes.

Selected material:— Rio de Contas, Lower NE slopes of the Pico das Almas, 17 February 1977, fl. and fr., R.M. Harley 19566 (K).

Comments:— Genlisea tuberosa can be readily distinguished from the other yellow flowered congeners in Bahia by its stolons with tubers, glandular and acute spur, and capsule covered with both eglandular and glandular trichomes. This species is endemic to Brazilian campos rupestres vegetation, and in Bahia is only found in Pico das Almas, municipality of Rio de Contas .
