Utricularia brennanii

A small terrestrial bladderwort of northern Australia, described in 2022 by Jobson and Baleeiro. It grows in wet-season seepages, swampy grassland and wet savannah in the Top End and Queensland, flowering from about January to July. The sites are hot, with a very wet summer and a bone-dry winter, so in cultivation it is best treated as a wet-season annual.
