Utricularia chrysantha is a terrestrial bladderwort native to monsoonal northern Australia. The species is named in reference to its yellow blooms.
U. chrysantha is widely variable in both colour and flower morphology. The lower corolla lip generally has four distinct lobes, with a prominant two-domed bulbous protruberance at the centre of the bloom. These lobes vary widely in their size. The upper corolla lip is usually rounded or slightly notched at the centre. The spur is rather straight and pointed at an obtuse angle away from the lower corolla lip. The flowers are most commonly deep yellow, sometimes with orange coloured centers. The flower scape is thin and moderately tall.
The species is probably the most common Utricularia in the Northern Territory, growing wherever wet sandy substrates are available. As the waters receed, the plants within a population often bloom together at the same time and put on very pretty en mass flowering displays. The species will continue to bloom until the ground is bone dry, persisting as seed over the dry season.
U. chrysantha shares its colouration with many species across its range. In Australia, it can be distinguished by its terrestrial nature; thin, tall and non-twining flower stalks; and four-lobed lower corolla lip with two-domed bulbous centre.
