Utricularia volubilis is an unusual affixed aquatic Utricularia from Western Australia. The image shows a rosette of this species attached to a green runner stolon. The large traps can be seen on short stalks attached to the rosette. Traps are often held on the tips of some of the grass like leaves. Both of these types of traps are suspended in the water. The largest traps of all are attached to the underground stolons and presumably trap prey which lives in this substrate. I have not yet studied these three trap types microscopically to determine differences between them.
