2.22. Utricularia nervosa Weber ex Benj. in Mart., Flora Brasiliensis 10: 247 (1847). [ Figs. 1 and 7I ].

Terrestrial or helophyte. Aerial linear leaves. Slender and slightly stiff scape, pubescent base. Peltate bracts, entire margins, absent bracteoles. Ascending pedicels in fruits. Sepals with conspicuous and prominent nerves, plan and entire margins. Yellow corolla, gibbous palate, trilobed lower lip, straight and subulate/bifid/quadrifid spur, longer than and parallel to the lower lip. Capsule dehiscing by a ventral pore.

Selected material:— Cocos, Fazendas Trijunção, estrara para a Sede do Guará , 11 December 2001, fl. and fr., B.M.T. Walter 4900 ( CEN); Barreiras , s.d., fl., A. Cotrim 474 ( HUEFS); São Desidério, 150 km SW of Barreiras, Rio Piau, 13 April 1966, fl., H.S. Irwin 14758 ( US) .

Comments:— Utricularia nervosa can be confused with U. flaccida (see comments section in this species) and U. subulata , but it differs from U. subulata by its scape with pubescent base and corolla larger (≥ 1.2 cm long) (vs. scape with glabrous base and corolla smaller [≤ 1 cm long]). In Bahia state, this species is found only in areas of veredas.
