Utricularia uliginosa

A small, usually annual bladderwort of seasonally flooded sandy pools, stream banks and rocky stream beds, growing on wet ground or partly submerged across tropical and subtropical Asia, the western Pacific and northern and eastern Australia. It traps tiny prey in bladders on its underground and underwater stems and sends up small spikes of lilac to purple flowers. In cultivation it is easy in a tray of wet sandy peat in bright light and seeds itself freely.
