Comments:— Utricularia blanchetii can be confused with U. parthenopipes and U. purpureocaerulea , but it differs from U. parthenopipes by its purple to lilac corolla, subreniform upper lip, slightly curved and subulate spur, longer than and parallel to the lower lip (vs. white corolla with purple streaks on the upper lip, cuneate and trilobed upper lip, straight to slightly curved and acute/bifid spur, constricted above the middle, shorter than and perpendicular to the lower lip); and from U. purpureocaerulea by its sepals with conspicuous but non-prominent nerves and denticulate margins (vs. sepals with conspicuous and prominent nerves and entire margins).This species was previously considered endemic to the campos rupestres of the Chapada Diamantina highlands until it was also reported for Pernambuco state ( Guedes et al. 2018).
