It is a liana, with a three-stage lifecycle, each with a different shaped leaf, as indicated by its Greek name. In the first stage, T. peltatum has simple lance-like leaves, and looks nondescript. It then develops long, glandular leaves, like those of the related Drosophyllum. These sticky leaves capture insects. The plant then enters its adult liana form, with short non-carnivorous leaves on a long twining stem.
