Comments:— Utricularia rostrata can be confused with U. costata (see comments in U. costata ). This species is endemic to the campos rupestres of Bahia, and as aforementioned, it was previously considered restricted to the central portions of the Chapada Diamantina highlands ( Fleischmann & Rivadavia 2009), and now its known distribution extends to Serra do Orobó (municipality of Ruy Barbosa) and near a mining area (municipality of Caetité), which are the northernmost and southernmost known populations of the species, respectively.
