They include the smallest flowering plants on Earth. [2] Commonly called watermeal or rootless duckweed, [3] [4] these aquatic plants resemble specks of cornmeal floating on the water. They often float together in pairs or form floating mats with related plants, such as Lemna and Spirodela species.
Salvinia natans has two nickel-sized leaves lying flat against the surface of the water, and a third submerged leaf which functions as a root. Flotation is made possible by pouches of air within the leaves. Cuticular papillae on the leaves' surface keep water from interfering with the leaves' functioning, and serve to protect them from decay ...
Aquatic plants require special adaptations for prolonged inundation in water, and for floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma , but floating leaves and finely dissected leaves are also common.
These plants have a simple structure, lacking an obvious stem or leaves. The greater part of each plant is a small organized "thallus" or "frond" structure only a few cells thick, often with air pockets that allow it to float on or just under the water surface. Depending on the species, each plant may have no root or may have one or more simple ...
Azolla filiculoides (red azolla) is the only member of the family Azollaceae found in Tasmania, where it is a common native aquatic plant. It is often found behind farm dams and other still waterbodies. The plants are small (usually only a few cm across) and float, but they are fast growing, and can be abundant and form large mats.
Salvinia or watermosses [1] is a genus of free-floating aquatic ferns in the family Salviniaceae.The genus is named in honor of 17th-century Italian naturalist Anton Maria Salvini, and the generic name was first published in 1754 by French botanist Jean-François Séguier in Plantae Veronenses, a description of the plants found around Verona.

The leaves grow in joined sets of three, with two leaves floating on the surface and one leaf dissected, hanging underneath. [4] This species is rootless but the dissected leaves that hang down act as root-like structures and are longer than the floating leaves. [4] Fine white hairs grow uniformly on the leaf surface and serve to repel water.
