Question: Are Vernonia and Pistia both aquatic plants?
Context: 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. Mansonia mosquitoes are big, black or brown mosquitoes with sparkling on their wings and legs.  They breed in ponds and lakes containing certain aquatic plants, especially the floating type like "Pistia stratiotes" and water hyacinth.  The eggs are laid in star-shaped clusters on the undersurface of leaves of these plants.  The larvae and pupae are found attached to the rootlets of these plants by their siphon tubes.  They obtain their air supply from these rootlets.  When about to become adult, these pupae come to the surface of water and the fully formed adults emerge and escape.  The control of "Mansonoia" mosquitoes is easy by removal or destruction of the aquatic host plants by herbicides. 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. Aquatic plants are used to give the 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.  Hobby aquarists use aquatic plants for aquascaping. 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. Aquatic plants are used to give the 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.  Hobby aquarists use aquatic plants for aquascaping. Vernonia is a genus of about 1000 species of forbs and shrubs in the family Asteraceae.  Some species are known as ironweed.  Some species are edible and of economic value.  They are known for having intense purple flowers.  The genus is named for the English botanist William Vernon.  There are numerous distinct subgenera and subsections in this genus.  This has led some botanists to divide this large genus into several distinct genera.  For instance, the "Flora of North America" only recognizes about 20 species in "Vernonia" sensu stricto, 17 of which are in North America north of Mexico, with the others being found in South America. Pistia is a genus of aquatic plant in the arum family, Araceae.  The single species it comprises, Pistia stratiotes, is often called water cabbage, water lettuce, Nile cabbage, or shellflower.  Its native distribution is uncertain, but probably pantropical; it was first discovered from the Nile near Lake Victoria in Africa.  It is now present, either naturally or through human introduction, in nearly all tropical and subtropical fresh waterways.  The genus name is derived from the Greek word πιστός ("pistos"), meaning "water," and refers to the aquatic nature of the plants. 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. 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.
