Alisma is a genus of flowering plants in the family Alismataceae, members of which are commonly known as water-plantains. The genus consists of aquatic plants with leaves either floating or submerged, found in a variety of still water habitats around the world (nearly worldwide). [1] [2] The flowers are hermaphrodite, and are arranged in panicles, racemes, or umbels. Alisma flowers have six stamens, numerous free carpels in a single whorl, each with 1 ovule, and subventral styles. The fruit is an achene with a short beak.
The nineteenth century British art and social critic John Ruskin believed that the particular curve of the leaf-ribs of Alisma represented a model of 'divine proportion' and helped shape his theory of Gothic architecture. [3]
Copóg Phádraig ("Patrick's leaf") is the Irish name for the water-plantain. It is reputed to ward off fairies. [4]
Water plantains are perennial plants. These herbs are usually emergent plants 0.1–1 m (4–40 in) high. They have broad leaves that can be either tapered or rounded at the base. When submerged, the plant produces ribbon-like leaves. Inflorescences are highly branched. They produce whorls of perfect flowers either white or pinkish. The fruits are flat-sided nutlets 2.5–3 mm (0.098–0.118 in) in length. These herbs usually flower in late May to early September, but this can vary with conditions. [5]
Water-plantains are wetland plants and found in saturated soils and shallow water as well as marshes, wooded swamps, shrub swamps and flooded farmland. When introduced to an area, water plantain can rapidly reproduce.
The following taxa are recognized as of May 2014: [2]
Spearmint, a species of mint (mentha) scientifically classified as Mentha spicata (,) also known as garden mint, common mint, lamb mint and mackerel mint, is native to Europe and southern temperate Asia, extending from Ireland in the west to southern China in the east. It is naturalized in many other temperate parts of the world, including northern and southern Africa, North America, and South America. It is used as a flavouring in food and herbal teas. The aromatic oil, called oil of spearmint, is also used as a flavoring and sometimes as a scent.
Sorrel, also called common sorrel or garden sorrel, is a perennial herbaceous plant in the family Polygonaceae. Other names for sorrel include spinach dock and narrow-leaved dock.
Plantago is a genus of about 200 species of flowering plants in the family Plantaginaceae, commonly called plantains or fleaworts. The common name plantain is shared with the unrelated cooking plantain. Most are herbaceous plants, though a few are subshrubs growing to 60 centimetres tall.
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, and apparently spread elsewhere in both the Old and New World.
Solidago virgaurea, the European goldenrod or woundwort, is an herbaceous perennial plant of the family Asteraceae. It is widespread across most of Europe as well as North Africa and northern, central, and southwestern Asia. It is grown as a garden flower with many different cultivars. It flowers profusely in late summer.
Plantago major, the broadleaf plantain, white man's footprint, waybread, or greater plantain, is a species of flowering plant in the plantain family Plantaginaceae. The plant is native to Eurasia.
Luronium natans is a species of aquatic plant commonly known as the floating water-plantain. It is the only recognized species in the genus Luronium, native to western and central Europe, from Spain to Britain to Norway east to Ukraine.
Plantago maritima, the sea plantain, seaside plantain or goose tongue, is a species of flowering plant in the plantain family Plantaginaceae. It has a subcosmopolitan distribution in temperate and Arctic regions, native to most of Europe, northwest Africa, northern and central Asia, northern North America, and southern South America.
Anthyllis vulneraria, the common kidneyvetch, kidney vetch or woundwort is a medicinal plant native to Europe. The name vulneraria means "wound healer".
Alisma gramineum is a small aquatic plant in the water-plantain family. It has several common names including narrowleaf water-plantain, ribbonleaf water-plantain or ribbon-leaved water-plantain, and grass-leaved water-plantain. It grows in mud or submerged in shallow fresh or brackish water in marshy areas.
Alisma lanceolatum is a species of aquatic plant in the water plantain family known by the common names lanceleaf water plantain and narrow-leaved water plantain. It is widespread across Europe, North Africa and temperate Asia. It is naturalized in Australia, New Zealand, Oregon, California and British Columbia. It is considered a noxious weed in some places.
Sagittaria montevidensis is a species of flowering plant in the water-plantain family Alismataceae. Common names include giant arrowhead and California arrowhead.
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.
Najas marina is a species of aquatic plant known by the common names spiny water nymph, spiny naiad and holly-leaved naiad. It is an extremely widespread species, reported across Europe, Asia, Africa, Australia, the Americas and many oceanic islands. It can be found in many types of freshwater and brackish aquatic habitat, including bodies of alkaline water.
Alisma subcordatum, the American water plantain, is a perennial aquatic plant in the water-plantain family (Alismataceae). This plant grows to about 3 feet in height with lance to oval shaped leaves rising from bulbous corms with fibrous roots. Any leaves that form underwater are weak and quick to rot; they rarely remain on adult plants. A branched inflorescence with white to pink 3-petaled flowers blooms from June to September. The seeds are eaten by waterfowl and upland birds. Native Americans dried and ate the submerged rootlike structures. The species name subcordatum means "almost heart-shaped".
Railway Stell West is a Site of Special Scientific Interest in the Sedgefield district of County Durham, England. The site consists of a length of ditch alongside the East Coast Main Line railway, 3 km east of the town of Newton Aycliffe.
Alisma orientale, commonly known as Asian water plantain is a flowering plant species in the genus Alisma found in Asia.
Doronicum plantagineum, the plantain-leaved leopard's-bane or plantain false leopardbane, is a European plant species in the sunflower family. It is native to southeastern Europe from Greece and Italy to Ukraine and the Czech Republic. There are reports of the species being naturalized in the State of Oregon in the northwestern United States.
Plantago indica, commonly known as branched plantain, sand plantain, or black psyllium, is a flowering plant in the plantain family Plantaginaceae, and is one of a few species in the Plantago genus under the common name psyllium. The plant is native to parts of Africa, Europe, Russia, and Asia, and has been naturalized in many other areas such as Australia and North America. The plant can be found mostly in dry inland areas, such as those that are sandy, and has also naturalized on roadsides and in meadows. The plant is not used broadly as a food source, but has been cultivated for its seeds which serve a medicinal use as a laxative.
