Utricularia australis is a medium-sized, perennial species of aquatic bladderwort.[1] This species has a vast geographic range, being found throughout Europe, in tropical and temperate Asia including China and Japan in the east, Central and Southern Africa, Australia and the North Island of New Zealand. The specific epithet "australis" is Latin for "southern" and reflects the fact that the discovery of this species was made in Australia in 1810.[1]
