Utricularia multifida is a terrestrial bladderwort endemic to Western Australia. The species is particularly known for its en mass displays of purple flowers, which emerge at the the end of winter.
Like other members of the subgenus Polypompholyx (which was once regarded as a genus in its own right), the blooms of U. multifida have a lower corolla that is divided into three prominent lobes. These blooms are vivid pink with yellow ridges on the palate. The leaves are inconspicuous and the traps are subterranean.
The species can usually be found in seasonally wet habitats across south west Western Australia, especially depressions and channels atop granite outcrops, and the floodplains of swamps. This annual species races to mature within a single growing season, setting seed before the hot and dry summer desiccates its habitat.
Utricularia multifida is closely related to two other species in the subgenus Polypompholyx. It is distinguished from U. westonii by its pink blooms and lack of giant surface traps (U. westonii has white blooms and produces large traps above the substrate). The species is extremely similar to U. tenella but is larger in size with flower lobes that are generally divided or flattened at the end (U. tenella is diminutive, usually reaching no more than 1-2 cm in height).
