2.19. Utricularia nelumbifolia Gardner in Hook., Icones Plantarum 6: 504 (1843). [ Figs. 1 and 7E–F ].

Terrestrial, lithophyte or epiphyte. Aerial circular, peltate leaves. Slender and slightly stiff scape. Basifixed and free bracts and bracteoles, entire margins. Ascending pedicels in fruits. Sepals with conspicuous but non-prominent nerves, plan and entire margins. Purple to pale lilac corolla, gibbous palate with two yellow crests, trilobed lower lip, circular well-developed lateral lobes and obsolete middle lobe, curved and acute spur, longer than and parallel to the lower lip. Longitudinally dehiscing capsule.

Selected material:— Itamaraju , Morro do Pescoço, 11 February 2007, bud., A.M. Amorim 6905 ( CEPEC) .

Additional material:— BRAZIL. Espírito Santo: Castelo, Parque Estadual do Forno Grande , 21 January 2009, fl.and fr., C.N. Fraga 2372 ( CEPEC) .

Comments:— Utricularia nelumbifolia can be confused with U. nephrophylla , but it differs from its circular and peltate leaves, and purple to pale lilac corolla (vs. reniform leaves, and white corolla). This species is endemic to Brazil and here we report a new record for Bahia state, located on an inselberg, and representing the northernmost known population of the species.
