Ranunculus Baudotii
''Ranunculus baudotii'', brackish water-crowfoot, is a flowering plant in the Ranunculaceae (buttercup family). 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. Description Brackish water-crowfoot is an annual or perennial aquatic plant with stems up to 3 m long, becoming terrestrial as its habitat dries out in summer. The submerged capillary leaves are usually about 5 cm long, but exceptionally as much as 15 cm, and are characteristically shorter than the adjacent stem internode. The floating and terrestrial laminar leaves are typically deeply 3-lobed (divided more than halfway to the base) with and up to 1 cm long by 2.5 cm wide. All the leaves are arranged alte ...

Dominique Alexandre Godron
Dominique Alexandre Godron (25 March 1807 - 16 August 1880) was a French physician, botanist, geologist and speleologist born in the town of Hayange, in the ''département'' Moselle. Godron studied medicine at the University of Strasbourg, and during his career distinguished himself in natural sciences as well as in the field of medicine. In 1854 he became dean and professor of natural history to the Faculty of Sciences at Nancy. Here he established a natural history museum and reorganized its botanical garden (now the '' Jardin Dominique Alexandre Godron'', renamed in his honor). Among his numerous writings were a publication on the flora of the Lorraine region of France called "''Flore de Lorraine''" (1843), and the three-volume "''Flore de France''", a work on flora native to France and Corsica that was co-written with botanist Jean Charles Marie Grenier (1808-1875). In addition to his botanical works, he published a number of studies in the field of ethnology. Before Men ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ranunculus Aquatilis
''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. This is an aquatic plant Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that ..., growing in mats on the surface of water. It has branching thread-like underwater leaves and toothed floater leaves. In fast flowing water the floaters may not be grown. The flowers are white petaled with yellow centres and are held a centimetre or two above the water. The floater leaves are used as props for the flowers and are grown at the same time.Blamey, M. & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''.

Aquatic Plants
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecologi ...

Ranunculus
''Ranunculus'' is a large genus of about almost 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. The genus is distributed in Europe, North America and South America. The familiar and widespread buttercup of gardens throughout Northern Europe (and introduced elsewhere) is the creeping buttercup ''Ranunculus repens'', which has extremely tough and tenacious roots. Two other species are also widespread, the bulbous buttercup ''Ranunculus bulbosus'' and the much taller meadow buttercup ''Ranunculus acris''. In ornamental gardens, all three are often regarded as weeds. Buttercups usually flower in the spring, but flowers may be found throughout the summer, especially where the plants are growing as opportunistic colonizers, as in the case of garden weeds. The water crowfoots (''Ranunculus'' subgenus ''Batrachium''), which grow in still or running water, are sometimes tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axiophyte
An axiophyte (Greek: "worthy plant") is a plant that is of particular interest to botanists, conservationists and ecologists. The significance of axiophytes is from their strong association with habitats considered to be of high merit for conservation. Axiophytes are a relatively recent concept which has its roots in such ideas as "ancient woodland indicator species". According to the BSBI around 40% of plant species can be considered axiophytes. Very rare species are not considered axiophytes; for a species to be a useful indicator of quality habitat it must be relatively frequent in those habitats, but scarce elsewhere. A typical example would be dog's mercury (''Mercurialis perennis''), a plant slow to colonise new sites, but common in ancient woodland and old hedgerows. The number of axiophytes on a site provides a crude, but convenient, measure of its nature conservation importance. It is a particularly useful approach when comparing otherwise similar sites. Over time axio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bolboschoenus Maritimus
''Bolboschoenus maritimus'' is a species of flowering plant from family Cyperaceae.

Ranunculus Trichophyllus
''Ranunculus trichophyllus'', the threadleaf crowfoot, or thread-leaved water-crowfoot, 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. 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. The segmented leaves and the plants ability to photosynthesis underwater have been studied. Taxonomy 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. The species epithet ''trichophyllus'' is Latin for 'hairy leaves'. In North America it is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
