Baldellia Ranunculoides
''Baldellia ranunculoides'', the lesser water-plantain, is a species of flowering plant in the family Alismataceae. Synonyms Alisma ranunculoides, Echinodorus ranunculoides, Sagittaria ranunculodes Description ''Baldellia ranunculoides'' is an aquatic plant which produced erect flowering stems that rise up to above the water surface. Each flower stalk bears one or two umbels of up to five flowers each, and often only a single flower. Each flower is in diameter, and has three petals. When not in flower, ''B. ranunculoides'' can be mistaken for lesser spearwort, ''Ranunculus flammula'', which grows in similar locations. Distribution ''Baldellia ranunculoides'' is found along the Atlantic and Baltic coast of western and northern Europe, and along the Mediterranean coasts of southern Europe, Turkey and North Africa. Recently found in eastern Newfoundland, Bristol's Hope barachois, Avalon Peninsula, the only location in North America. May have been introduced by a float (Sarr ...

Pteridium Aquilinum
''Pteridium aquilinum'' (bracken, brake or common bracken), also known as eagle fern, is a species of fern occurring in temperate and subtropical regions in both hemispheres. Originally native to Eurasia and North America, the extreme lightness of its spores has led to it achieving a cosmopolitan distribution. Etymology Common bracken was first described as ''Pteris aquilina'' by Carl Linnaeus, in Volume 2 of his ''Species Plantarum'' in 1753. The origin of the specific epithet derived from the Latin ''aquila'' "eagle". In the reprint of the ''Flora Suecica'' in 1755, Linnaeus explains that the name refers to the image of an eagle seen in the transverse section of the root. In spite of this, the opinion has been forwarded that the name pertains to the shape of the mature fronds appearing akin to an eagle's wing. However, medieval scholars, including Erasmus, thought the pattern of the fibres seen in a transverse section of the stipe resembled a double-headed eagle or oak tree. Ta ...

Rubus Fruticosus
''Rubus fruticosus'' L. is the ambiguous name of a European blackberry species in the genus ''Rubus'' in the rose family. The name has been interpreted in several ways: *The species represented by the type specimen of ''Rubus fruticosus'' L., which is also the type specimen of the genus ''Rubus''. This specimen is considered to match the species '' R. plicatus'', in ''Rubus'' subgenus ''Rubus'', section ''Rubus''. * Various species consistent with Linnaeus' original description of the species, which was based on a mixture of specimens now considered to match ''Rubus ulmifolius'' and ''R. plicatus'' *a species aggregate (group of similar species) ''Rubus fruticosus'' agg. (a ''nomen ambiguum'') that includes most (or rarely all) of a group called ''Rubus'' subgenus ''Rubus'' (or less often: ''Rubus'' section ''Rubus'' ensu latissimo): ** in a narrow sense, sometimes separated as the section ''Glandulosus'' (alternative name: subsection ''Hiemales''), with about 289 microspeci ...

Lotus Pedunculatus
''Lotus pedunculatus'' (formerly ''Lotus uliginosus''), the big trefoil, greater bird's-foot-trefoil or marsh bird's-foot trefoil, is a member of the pea family (Fabaceae). It is a herbaceous perennial growing throughout Europe in damp, open locations. As one common name suggests, it is a larger plant than related '' Lotus'' species, growing tall, with leaflets long and broad. Five to twelve golden-yellow flowers long are borne in an umbel at the tip of the upright stem. Unlike related species, the stem is always hollow, and the sepals turn back at their tips – these sepal tips form a characteristic "green star" at the end of the flower bud. The peak flowering period in the United Kingdom is June and July. ''Lotus pedunculatus'' occurs in a wide range of neutral, damp, open habitats, including certain fen-meadow plant associations such as ''Juncus subnodulosus''-''Cirsium palustre'' fen-meadow habitat. ''Lotus pedunculatus'' is also a host plant for ovipositioning of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lychnis Flos-cuculi
''Silene flos-cuculi'' (syn. ''Lychnis flos-cuculi''), commonly called ragged-robin, is a perennial herbaceous plant in the family Caryophyllaceae. This species is native to Europe and Asia, where it is found along roads and in wet meadows and pastures. In Britain it has declined in numbers because of modern farming techniques and draining of wet-lands and is no longer common. However, it has become naturalized in parts of the northern United States and eastern Canada. Description ''Silene flos-cuculi'' forms a rosette of low growing foliage with numerous flower stems 20 to 90 cm tall. The stems rise above the foliage and branch near the top of the stem and end with the pink flowers which are 3–4 cm across. The flowers have five narrow petals deeply divided into four lobes giving the flower an untidy, ragged appearance, hence its common name. The calyx tube is five-toothed with ten stamens. The leaves are paired, with the lower leaves spoon-shaped and stalked. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juncus Effusus
''Juncus effusus'', with the common names common rush or soft rush, is a perennial herbaceous flowering plant species in the rush family Juncaceae. In North America, the common name soft rush also refers to '' Juncus interior''. Distribution ''Juncus effusus'' is nearly cosmopolitan, considered native in Europe, Asia, Africa, North America, and South America. It has naturalized in Australia, Madagascar, and various oceanic islands. It is found growing in wet areas, such as wetlands, riparian areas, and marshes. In the United Kingdom it is found in purple moor-grass and rush pastures and fen-meadow plant associations. Description ''Juncus effusus'' grows in large clumps about tall at the water's edge along streams and ditches, but can be invasive anywhere with moist soil. It is commonly found growing in humus-rich areas like marshes, ditches, fens, and beaver dams. The stems are smooth cylinders with light pith filling. The yellowish inflorescence appears to emerg ...

Salix Cinerea
''Salix cinerea'' (common sallow, grey sallow, grey willow, grey-leaved sallow, large grey willow, pussy willow, rusty sallow) is a species of willow native to Europe and western Asia.Meikle, R. D. (1984). ''Willows and Poplars of Great Britain and Ireland''. BSBI Handbook No. 4. .Christensen, K. I., & Nielsen, H. (1992). Rust-pil (''Salix cinerea'' subsp. ''oleifolia'') - en overset pil i Danmark og Skandinavien. ''Dansk Dendrologisk Årsskrift'' 10: 5-17. The plant provides a great deal of nectar for pollinators. It was rated in the top 10, with a ranking of second place, for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. Plant It is a deciduous shrub or small tree growing 4–15 metres (13–50 ft) tall. The leaves are spirally arranged, 2–9 cm (1– in) long and 1–3 cm (– in) broad (exceptionally up to 16 cm ...

Juncus
''Juncus'' is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species. Description Rushes of the genus ''Juncus'' are herbaceous plants that superficially resemble grasses or sedges. They have historically received little attention from botanists; in his 1819 monograph, James Ebenezer Bicheno described the genus as "obscure and uninviting". The form of the flower differentiates rushes from grasses or sedges. The flowers of ''Juncus'' comprise five whorls of floral parts: three sepals, three petals (or, taken together, six tepals), two to six stamens (in two whorls) and a stigma with three lobes. The stems are round in cross-section, unlike those of sedges, which are typically somewhat triangular in cross-section. In ''Juncus'' section ''Juncotypus'' (formerly called ''Juncus'' subg. ''Genuini''), which contains some of the most widespread and familiar species, the leaves are reduced t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phragmites Australis
''Phragmites australis'', known as the common reed, is a species of plant. It is a broadly distributed wetland grass that can grow up to tall. Description ''Phragmites australis'' commonly forms extensive stands (known as reed beds), which may be as much as or more in extent. Where conditions are suitable it can also spread at or more per year by horizontal runners, which put down roots at regular intervals. It can grow in damp ground, in standing water up to or so deep, or even as a floating mat. The erect stems grow to tall, with the tallest plants growing in areas with hot summers and fertile growing conditions. The leaves are long and broad. The flowers are produced in late summer in a dense, dark purple panicle, about long. Later the numerous long, narrow, sharp pointed spikelets appear greyer due to the growth of long, silky hairs. These eventually help disperse the minute seeds. Taxonomy Recent studies have characterized morphological distinctions between the int ...

Variscan Orogeny
The Variscan or Hercynian orogeny was a geologic mountain-building event caused by Late Paleozoic continental collision between Euramerica (Laurussia) and Gondwana to form the supercontinent of Pangaea. Nomenclature The name ''Variscan'', comes from the Medieval Latin name for the district '' Variscia'', the home of a Germanic tribe, the Varisci; Eduard Suess, professor of geology at the University of Vienna, coined the term in 1880. (Variscite, a rare green mineral first discovered in the Vogtland district of Saxony in Germany, which is in the Variscan belt, has the same etymology.) ''Hercynian'', on the other hand, derives from the Hercynian Forest. Both words were descriptive terms of strike directions observed by geologists in the field, ''variscan'' for southwest to northeast, ''hercynian'' for northwest to southeast. The ''variscan'' direction reflected the direction of ancient fold belts cropping out throughout Germany and adjacent countries and the meaning shifted from d ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
