Wolffia are free-floating aquatic plants with fronds that are nearly spherical to cylindrical in shape and lack airspaces or veins. [1] [3] They do not have roots. [1]Their rarely seen flowers originate from a cavity on the upper surface of the frond, and each flower has one stamen and one pistil.
Pistia is a genus of aquatic plants in the arum family, Araceae.It is the sole genus in the tribe Pistieae which reflects its systematic isolation within the family. [5] The single species it comprises, Pistia stratiotes, is often called water cabbage, water lettuce, Nile cabbage, or shellflower.
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.
The plants use nitrogen and phosphorus produced from fish waste as fertilizer, while simultaneously cleaning the water as it grows. The water can then be reused by the aquaculture farmers, and the duckweed, which has a 35-42% protein content, can be harvested as a source of sustainable plant-based protein. [38]
Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, absorb ammonia, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.
Delivering the water slower and in smaller doses directly at the plant’s root can save as much as 50% to 70% of misting. Runoff, wind drift and evaporation are also minimized this way.
