Alisma plantago-aquatica, also known as European water-plantain, common water-plantain or mad-dog weed, is a perennial flowering aquatic plant widespread across most of Europe and Asia from Portugal and Morocco to Japan, Kamchatka and Vietnam. It is also regarded as native in northern and central Africa as far south as Tanzania. It is reportedly naturalized in southern Africa, Australia, New Zealand, Alaska, British Columbia, Washington State and Connecticut. Some sources maintain that the species is widespread across North America, but these reports appear to have been based on misidentified specimens. It is found on mud or in fresh waters.
Ipomoea aquatica is a semi-aquatic, tropical plant grown as a vegetable for its tender shoots and it is not known where it originated. This plant is known in English as water spinach, river spinach, water morning glory, water convolvulus, or by the more ambiguous names Chinese spinach, Chinese watercress, Chinese convolvulus or swamp cabbage, or kangkong in Southeast Asia and ong choy in Cantonese.
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.
Stillingia is a plant genus of the family Euphorbiaceae, first described for modern science as a genus in 1767. The genus is native to Latin America, the southern United States, and various islands in the Pacific and Indian Oceans. Toothleaf is a common name for plants in this genus.
Ditrysinia is a plant genus of the family Euphorbiaceae first described as a genus in 1825. It contains only one recognized species, Ditrysinia fruticosa, the Gulf Sebastian-bush, native to the southeastern United States.
Corkwood is a common name of a number of plants:
Nyssa aquatica, commonly called the water tupelo, cottongum, wild olive, large tupelo, tupelo-gum, or water-gum, is a large, long-lived tree in the tupelo genus (Nyssa) that grows in swamps and floodplains in the Southeastern United States.
Ilex amelanchier, the swamp holly or sarvis holly, is a rare species of holly from the southeastern United States. It is a close relative of mountain holly which used to be placed in a monotypic genus Nemopanthus. Ilex amelanchier grows near water, for example on streambanks.
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.
Planera is a genus of flowering plants with a single species, Planera aquatica, the planertree or water elm. 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. The leaves are 3–7 cm long, with a serrated margin. 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.
Stillingia spinulosa is a species of flowering plant in the euphorb family known by the common name annual toothleaf. It is native to the Southwestern United States where it occurs in the creosote scrub of the deserts. It is an annual or perennial herb producing a clump of thick, leafy stems approaching a meter in maximum height. The alternately arranged leaves have shiny pointed oval blades 2 to 4 centimeters long and up to 1.2 centimeters wide which are lined with sharp teeth. The inflorescence is a stout spike of flowers 1 to 2 centimeters long. The plant is monoecious, and each spike has several male flowers at the tip and 1 or 2 fruit-bearing female flowers below these. Neither type of flower has petals. The ovary of the female flower develops into a three-lobed greenish capsule about half a centimeter wide. There is a tiny rough-surfaced seed in each of the three chambers of the fruit.
Veronica anagallis-aquatica is a species of flowering plant in the family Plantaginaceae known by the common names water speedwell, blue water-speedwell,,brook pimpernel, and sessile water-speedwell. It is also listed as Veronica catenata. Its true native range is not clear, but the plant is present on most continents, and in most places it is probably naturalized. It occurs in many types of moist and wet habitat, and it is semi-aquatic, often growing in shallow water along streambanks, in ponds, and in other wetland environments. It is a rhizomatous perennial herb with stems growing 10 centimeters to about a meter in maximum length. It may be decumbent, the stem spreading along the ground and rooting where it touches moist substrate, or erect in form. The oppositely arranged leaves are green, smooth-edged or toothed, and sometimes clasping the stem where the leaf pairs meet at the bases. The inflorescence is a raceme of many flowers arising from the leaf axils. Each flower is borne on a short, curving pedicel. The flower corolla is up to a centimeter wide with four lobes, the upper lobe being widest. It is blue, lavender, or violet with purple lines near the base of each lobe. At the center are two small protruding stamens.
Oxypolis canbyi is a rare species of flowering plant in the carrot family known by the common names Canby's dropwort and Canby's cowbane. It is native to the southeastern United States, where it occurs on the Atlantic coastal plain from North Carolina to Georgia, as well as the Chesapeake Bay area. It is threatened by the loss of the wetland habitat in which it grows. It is a federally listed endangered species of the United States.
Jacobaea aquatica or Senecio aquaticus, the water ragwort or marsh ragwort, is a plant of the family Asteraceae. It is a perennial or biennial plant: young plants form a rosette near the ground, eventually producing a taller flowering shoot with many bright yellow flower heads, each with prominent ray florets. It grows in damp, grazed grassland, especially where there has been some disturbance.
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.
Stillingia texana, the Texas toothleaf, is a species of flowering plant in the family Euphorbiaceae. It is native to the South Central United States and Mexico. In central Texas it is widespread in upland, calcareous prairies, spreading north to scattered locations in Oklahoma and south to Coahuila. Stillingia texana was described in 1923 by Ivan Murray Johnston.
Stillingia treculiana, Trecul's toothleaf, is a species of flowering plant in the family Euphorbiaceae. It was originally described as Gymnanthes treculianaMüll.Arg. in 1865. It is native to southern Texas in the United States and northeast Mexico, growing in sandy and gravelly soils in dry habitats.
Stillingia paucidentata, the Mojave toothleaf, is a species of flowering plant in the spurge family, Euphorbiaceae. The Mojave toothleaf is endemic to southeastern California in the United States. It may occur in nearby western Arizona, but no specimens from that state have been conclusively confirmed. It grows in sandy areas and dry slopes, flowering between March and May and fruiting in May and June.
