Actaea, commonly called baneberry, bugbane and cohosh, is a genus of flowering plants belonging to the family Ranunculaceae, native to subtropical, temperate and subartic regions of the Europe, Asia and North America.
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater).
 They are also referred to as hydrophytes or macrophytes.
 These plants require special adaptations for living submerged in water, or at the water's surface.
 The most common adaptation is aerenchyma, but floating leaves and finely dissected leaves are also common.
 Aquatic plants can only grow in water or in soil that is permanently saturated with water.
 They are therefore a common component of wetlands.
Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, 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.

William Tricker (1852–1916) was an English-born estate gardener.
 He trained at Kew Gardens in London, before emigrating to the United States in the later 19th century.
 His interest was in aquatic plants, and he began a company, named William Tricker, that specialized in aquatic plants.
 The company sent out its first mail order catalog in 1892, and is still operating, as William Tricker, Inc. based in Independence, Ohio.
 The company currently displays Tricker's original catalog.
 Being a plantsman, he wrote many articles for the publication "Garden and Forest" in the 1890s dealing with aquatic plants.
 He is well known for producing many hybrid water lilies that are still known around the world.
 He introduced a water lily with 6-feet pads from South America, which he named "Victoria trickeri", although it is now known as "Victoria cruziana".
 He died in 1916, after which his son, Charles Tricker, took over the business.
Nymphoides indica is an aquatic plant in the Menyanthaceae, native to tropical areas around the world.
 It is sometimes cultivated, and has become a minor weed in Florida, where it resembles the native "Nymphoides aquatica".
 Common names include banana plant, robust marshwort, and water snowflake.
Nymphoides, or floatingheart, is a genus of aquatic flowering plants in the family Menyanthaceae.
 The genus name refers to their resemblance to the water lily "Nymphaea".
 "Nymphoides" are aquatic plants with submerged roots and floating leaves that hold the small flowers above the water surface.
 Flowers are sympetalous, most often divided into five lobes (petals).
 The petals are either yellow or white, and may be adorned with lateral wings or covered in small hairs.
 The inflorescence consists of either an umbellate cluster of flowers or a lax raceme, with internodes occurring between generally paired flowers.
Hygrophila, commonly known as swampweeds, is a genus of flowering plants in the acanthus family, Acanthaceae.
 There are about 80 to 100 species, of which many are aquatic plants.
 The genus is distributed across the tropical and subtropical world.
 It is one of only two genera in its family that contains aquatic plants, the other being "Justicia".
 The genus is treated in the tribe "Hygrophileae", which is noted as being in need of revision at the genus level, meaning the current taxonomic boundaries of "Hygrophila" are likely to change in the future.
Endothall or 3,6-endoxohexahydrophthalic acid is used as an herbicide for both terrestrial and aquatic plants.
 It is used as an aquatic herbicide for submerged aquatic plants and algae in lakes, ponds and irrigation canals.
 It is used as a desiccant on potatoes, hops, cotton, clover and alfalfa.
 It is used as a biocide to control mollusks and algae in cooling towers.

Question: Are Actaea and Nymphoides both aquatic plants?
