Scientific NameUtricularia gibba
No distinct leaves occur. However, the stem-like segments of this species are actually the leaves. Many distinctive bladders are attached to these segments. When removed from the water, the bladders are almost clear and have a pinkish-red color.Stems: Stems may be creeping, floating, or submersed, depending on the species. Stems are typically branching with bladders attached throughout. Roots: No true roots are present on the aquatic bladderwort species.
Submersed aquatic plants that float freely throughout the water and have no true roots. Bladderworts can be found in ponds, lakes, ditches, and bogs. Most bladderworts are free-floating aquatics, however some species may occur in marshes or along the edges of ponds, lakes, or bogs. The bladderworts are carnivorous plants that capture aquatic invertebrates in their bladders and then break these organisms down to nitrogen and other nutrients. The bladders that occur on the stems and leaves of all the Utricularia species helps to distinguish these weeds from any other floating or submerged aquatic weeds.
