Utricularia sandersonii
Sanderson's bladderwort
A terrestrial bladderwort that can be recognised by its spurred white flower that typically bears two distinct lobes above or "bunny ears" and is marked with pale blue on the lower lobes. Like other species, its carnivorous nature stems from the capture of micro-organisms by minute bladders on underground stems
