Ranunculus trichophyllus, the threadleaf crowfoot, [2] or thread-leaved water-crowfoot, [3] [4] is a plant species in the genus Ranunculus , native to Europe, Asia and North America.
It is a herbaceous annual or perennial plant generally found in slow flowing streams, ponds, or lakes. The daisy-like flowers are white with a yellow centre, with five petals. [5] It is similar in form to Ranunculus fluitans (river water-crowfoot), apart from flower petal number, thread-leaved has on 5 petals and shorter leaves, as thread-leaved prefers slower flowing waters. It also has rounded seed heads which become fruits covered with bristles. [5] The segmented leaves and the plants ability to photosynthesis underwater have been studied. [6]
It was first described and published by the French naturalist and botanist Dominique Villars in his book 'Histoire des plantes du Dauphiné' Vol.3 on page 335 in 1786. [1] [7]
The species epithet trichophyllus is Latin for 'hairy leaves'. [8]
In North America it is also commonly known as the 'white water crow foot'. [9] The Icelandic name of this species is Lónasóley. [10]
Subspecies:
The plant is found in most of the Northern Hemisphere, [4] from the United States, Europe and the Mediterranean, east through Siberia, the Caucasus, the Middle East, the Himalayas, Kazakhstan and Mongolia to Kamchatka in Russia, also in Japan, China and Korea. [12] It is even found in the lakes and ponds of Mount Everest. [13]
Phytoremediation is a plant-based approach, which involves the use of plants to extract and remove elemental pollutants or lower their bioavailability in soil. [14] Ranunculus trichophyllus, commonly known as the threadleaf crowfoot or Three-leaved Crowfoot, is a species of aquatic plant. It belongs to the buttercup family (Ranunculaceae). However, it's not a widely studied or economically significant plant, and information about its specific importance might be limited. Therefore, in terms of Phytoremediation, there is limited information other than the species participates in phytofiltration. Phytofiltration is a type of phytoremediation of heavy metal-polluted soil. Phytofiltration is the use of plant roots (rhizofiltratio)), shoots (caulofiltration), or seedlings (blastofiltration) to remove pollutants from contaminated surface waters or waste waters. During rhizofiltration, heavy metals are either adsorbed onto the root surface or absorbed by the roots. Root exudates can change rhizosphere pH, which leads to the precipitation of heavy metals on plant roots, further minimizing the movement of heavy metals to underground water. [14] Ranunculus trichophyllus is great in phytofiltration to deal with arsenic which is accumulated in aquatic plants and eliminated from water. [15]
It grows in freshwater, [16] found in dune slacks and drainage ditches to ponds, lakes, streams and slow-flowing rivers. It can be found up to 3,000 m (9,800 ft) above sea level. [12]
Ranunculaceae is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide.
Ranunculus is a large genus of about 1700 to more than 1800 species of flowering plants in the family Ranunculaceae. Members of the genus are known as buttercups, spearworts and water crowfoots.
Ranunculus repens, the creeping buttercup, is a flowering plant in the buttercup family Ranunculaceae, native to Europe, Asia and northwestern Africa. It is also called creeping crowfoot and sitfast.
The bronze-winged duck also known as the spectacled duck, is a dabbling duck and the sole member of its genus Speculanas. It is often placed in Anas with most other dabbling ducks, but its closest relative is either the crested duck or the Brazilian duck, which likewise form monotypic genera. Together they belong to a South American lineage which diverged early from the other dabbling ducks and may include the steamer ducks.
Bookham Commons are two commons, situated just to the north of the villages of Great Bookham and Little Bookham, in Surrey, England, 154.7 hectares in extent; the individual parts are named Great Bookham Common and Little Bookham Common. A group of dwellings known as the Isle of Wight is situated within the site, and a track, Common Road, leads to it from the northwest. Little Bookham Common lies south and west of this track, whereas Great Bookham Common lies to the east.
Ranunculus glacialis, the glacier buttercup or glacier crowfoot, is a plant of the family Ranunculaceae. It is a 5-10(-20) cm high perennial herb. Often with a single relatively large flower, with 5 petals first white later pink or reddish. The underside of the 5 sepals are densely brown-hairy. The leaves are fleshy, shiny, and deeply loped, forming 3 leaflets. Ranunculus glacialis is reported to have a diploid chromosome number of 2n = 16.
The North Somerset Levels is a coastal plain, an expanse of low-lying flat ground, which occupies an area between Weston-super-Mare and Bristol in North Somerset, England. The River Banwell, River Kenn, River Yeo and Land Yeo are the three principal rivers draining the area.
Ranunculus peltatus, the pond water-crowfoot, is a plant species in the genus Ranunculus, native to Europe, southwestern Asia and northern Africa.
Ranunculus aquatilis, the common water-crowfoot or white water-crowfoot, is a plant species of the genus Ranunculus, native throughout most of Europe and western North America, and also northwest Africa.
Ranunculus sceleratus known by the common names celery-leaved buttercup, celery-leaf buttercup, and cursed buttercup is a species of flowering plant in the buttercup family Ranunculaceae. It has a circumpolar distribution in the northern hemisphere, native to temperate and boreal North America and Eurasia, where it grows in wet and moist habitats, including ponds and streambanks.
Ranunculus fluitans is a species of buttercup. It is a perennial water plant, which when in favourable conditions can grow up to 6 m (20 ft) height.
Ranunculus gmelinii, Gmelin's buttercup or small yellow water-crowfoot, is a species of flowering plant in the buttercup family, Ranunculaceae. It is native to northern North America, where it occurs across Canada and the northern and higher-elevation regions of the United States. It is also present in Eurasia.
Ranunculus allenii, commonly known as Allen's buttercup, is a flowering plant in the crowfoot or buttercup family, Ranunculaceae. Generally found in wetlands in northern latitudes, it bears yellow flowers in summer, which are pollinated by insects.
Callitriche brutia, the pedunculate water-starwort, is a dwarf amphibious annual or perennial dicotyledon herb in the genus Callitriche. The common name of this species is water starwort. It colonizes aquatic environments, such as wetlands, lakes, rivers, streams, and pools, and it grows in oligotrophic conditions, meaning it grows in an environment that has little to sustain life. Pedunculate water-starwort was found in Ireland and England, but is now an invasive species due to its resistance to environmental stressors, and its ability to grow in still water.
Ranunculus lingua, the greater spearwort, great spearwort, tongue-leaved crowfoot, or water buttercup, is a plant species in the family Ranunculaceae native to temperate areas of Europe, Siberia and through to the western Himalayas. It is a semiaquatic plant that prefers to grow in about 40 cm (16 in) of water in a variety of wetland habitats. A cultivar called 'Grandiflorus', the large-flowered greater spearwort, has 6 cm flowers and is favored by gardeners.
Ranunculus allegheniensis is a species of flowering plant in the buttercup family, Ranunculaceae. Its common names include Allegheny Mountain buttercup and Allegheny crowfoot.
Ranunculus tripartitus is a species of flowering plant in the family Ranunculaceae, which grows in pools and muddy hollows in coastal parts of Europe, North Africa and West Asia. It is rare and endangered throughout its range, and is considered to be an indicator of favourable environmental conditions.
Ranunculus baudotii, brackish water-crowfoot, is a flowering plant in the Ranunculaceae. As the name suggests, it tends to grow near the sea, typically in pools and ditches in coastal marshes that are slightly salty due to sea spray. It can also be found inland where there is some saline influence. It is not edible and has economic uses, but it is generally valued as a plant of conservation interest and an indicator of less agriculturally improved habitat.
Ranunculus hederaceus is a flowering plant in the family Ranunculaceae.
