Pachira aquatica is a tropical wetland tree in the mallow family Malvaceae, native to Central and South America where it grows in swamps. It is known by its common names Malabar chestnut, French peanut, Guiana chestnut, Provision tree, Saba nut, Monguba (Brazil), Pumpo (Guatemala) and is commercially sold under the names Money tree and Money plant. This tree is sometimes sold with a braided trunk and is commonly grown as a houseplant, although more commonly what is sold as a "Pachira aquatica" houseplant is in fact a similar species, P. glabra.
Crassula aquatica is a succulent plant known by the common names water pygmyweed, common pygmyweed and just pigmyweed. It is an annual plant of salt marshes, vernal pools, wetlands, and other fresh to brackish water bodies. It is at least partially aquatic, living in areas which are submersed much of the time. It also lives along muddy banks and in tidally-active areas of estuaries.
Limnophila is a genus of flowering plants in the family Plantaginaceae. It is distributed in tropical and subtropical regions of Africa, Asia, Australia, and the Pacific Islands. Species are known commonly as marshweeds.
Planera aquatica, the planertree or water elm, is a species of flowering plant. Found in the southeastern United States, it is a small deciduous tree 10–15 m tall, closely related to the elms but with a softly, prickly nut 10–15 mm diameter, instead of a winged seed. It grows, as the name suggests, on wet sites. Despite its common English name, this species is not a true elm, although it is a close relative of the elms. It is also subject to Dutch elm disease, a disease which affects only members of the Ulmaceae. It is native to most of the southeast United States. It is hardy down to Zone 7.

Hellenia is a genus of plants in the Costaceae described as a genus with this name in 1791. It is native to Southeast Asia, southern China, the Indian Subcontinent, New Guinea, and Queensland. The type species was "H. grandiflora" Retz., which is a synonym of Hellenia speciosa.
Stylisma is a genus of flowering plants in the morning glory family, commonly known as dawnflowers. This genus is native to the eastern United States.
Oenanthe aquatica, fine-leaved water-dropwort, is an aquatic flowering plant in the carrot family. It is widely distributed from the Atlantic coast of Europe to central Asia.
Catabrosa aquatica, called brookgrass, water whorl-grass, water whirlgrass and water hairgrass, is a widespread species of semi-aquatic grass in the genus Catabrosa, native to the most of the non-tropical northern hemisphere, and to southern Chile and Argentina. As its scientific and common names suggest, it prefers to grow in wet areas, such as meadows, stream banks and lake shores.
Conobea is a genus of flowering plants belonging to the family Plantaginaceae.
Nepsera is a monotypic genus of flowering plants belonging to the family Melastomataceae. The only species is Nepsera aquatica.
Eragrostis aquatica is a species of grass, native to west Honshu island, Japan. It grows on the edges of wet areas, and has also been recorded from South Korea.
Rorippa aquatica, the lakecress or lake cress, is a species of freshwater aquatic flowering plant in the family Brassicaceae. It is found in eastern and central North America, generally in the Great Lakes and Mississippi watersheds. A submerged perennial, it has emergent flowering branches. It is typically found in slow-moving water, such as oxbow lakes. It is used as a foreground aquarium plant, as it is undemanding and very slow-growing.
