Buttercup
''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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ranunculus Acris
''Ranunculus acris'' is a species of flowering plant in the family Ranunculaceae, and is one of the more common buttercups across Europe and temperate Eurasia. Common names include meadow buttercup, tall buttercup, common buttercup and giant buttercup. Description ''Ranunculus acris'' is a herbaceous perennial plant that grows to a height of 30 to 70 cm, with ungrooved flowing stems bearing glossy yellow flowers about 25 mm across. There are five overlapping petals borne above five green sepals that soon turn yellow as the flower matures. It has numerous stamens inserted below the ovary. The leaves are compound, with three-lobed leaflets. Unlike '' Ranunculus repens'', the terminal leaflet is sessile. As with other members of the genus, the numerous seeds are borne as achenes. The rare autumn buttercup (''R. aestivalis'') is sometimes treated as a variety of this species. The juice of the plant is semi-poisonous to livestock, causing blistering. Distribution The pl ...

Ranunculus Repens
''Ranunculus repens'', the creeping buttercup, is a flowering plant in the buttercup family Ranunculaceae, native to Europe, Asia and northwestern Africa. Habitat It is a very common weed of agricultural land and gardens, spreading quickly by its rooting stolons and resisting removal with a deeply anchored filamentous root ball. In Ireland: very common in damp places, ditches and flooded areas.Hackney, P. (1992). ''Stewart and Corry's Flora of the North-east of Ireland.'' Third Edition. Institute of Irish Studies and The Queen's University of Belfast . Cultivation and uses Creeping buttercup was sold in many parts of the world as an ornamental plant, and has now become an invasive species in many parts of the world. Like most buttercups, ''Ranunculus repens'' is poisonous, although when dried with hay these poisons are lost. The taste of buttercups is acrid, so cattle Cattle (''Bos taurus'') are large, domesticated, cloven-hooved, herbivores. They are a prominent mod ...

Ranunculus Bulbosus
''Ranunculus bulbosus'', commonly known as bulbous buttercup or St. Anthony's turnip, is a perennial flowering plant in the buttercup family Ranunculaceae. It has bright yellow flowers, and deeply divided, three-lobed long-petioled basal leaves. Description The stems are 20–40 cm tall, erect, branching, and slightly hairy, with a swollen corm-like base.RH Uva, JC Neal and JM Ditomaso (1997) ''Weeds of The Northeast'', Cornell University Press, Ithaca, NY. pp. 294-295 There are alternate and sessile leaves on the stem. The flower forms at the apex of the stems, with 5–7 petals, the sepals strongly reflexed. The flowers are glossy yellow and 1.5–3 cm wide. The plant blooms from April to July. Distribution The native range of ''Ranunculus bulbosus'' is Western Europe between about 60°N and the Northern Mediterranean coast. It grows in both the eastern and western parts of North America as an introduced weed. Bulbous buttercup grows in lawns, pastures and fiel ...

Ranunculus Eschscholtzii
''Ranunculus eschscholtzii'' is a species of buttercup flower known by the common name Eschscholtz's buttercup. The species name honors Johann Friedrich von Eschscholtz, an Imperial Russian botanist and entomologist active on the West Coast in the 1820s and 1830s. Distribution and habitat The plant is native to much of western North America from the Arctic northwestern Canada and Alaska to California and New Mexico. It grows in meadows and talus on high mountain slopes and other open rocky habitat. Description ''Ranunculus eschscholtzii'' is a perennial herb producing one or more erect stems up to 20 or 25 centimeters tall. The lower leaves have somewhat rounded blades each divided into a few lobes and borne on long petioles. Any upper leaves are smaller and not borne on petioles. The herbage is hairless and sometimes waxy in texture. The inflorescence is made up of one to three flowers on narrow pedicels. The flower has five to eight oval or rounded shiny yellow petals up to ... [...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 are in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petal
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and '' Tulipa''. Conversely, genera such as ''Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Since they include Liliales, an alte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hebrew Character
The Hebrew character (''Orthosia gothica'') is a moth in the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae''. It is found throughout Europe. Both the common and binomial names of this moth refer to distinctive black markings, one on each wing. These markings resemble the Hebrew letter nun (), and also a gothic arch. Technical description and variation The wingspan is 30–40 mm. Forewing sandy rufous, black speckled, median area generally deeper rufous: lines browner, forewing purplish red brown; the lines pale, ill defined, except by black spots at costa; the cell black; stigmata pale and large; claviform connected with outer line by a black bar; above which the base of vein 2 is often surrounded with rufous; hindwing fuscous. The size of the orbicular stigma is variable, and the amount and shape of the black filling in of the cell is determined by this variation; — in ab. ''gothicina'' H.-Sch. the b ...

Small Angle Shades
The small angle shades (''Euplexia lucipara'') is a moth of the family Noctuidae. It is distributed throughout the Palearctic. The species was first described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae''. As the common name suggests, this species is closely related to the angle shades (''Phlogophora meticulosa''), and is considerably smaller (wingspan 30–35 mm), but does not especially resemble that species. The forewings are dark brown with a broad, pale subterminal band, wider and paler towards the costa. The hindwings are whitish at the base, graduating to brown at the margins. In the British Isles this species flies at night in June and July, with a second generation sometimes emerging in September. It is attracted to light and sugar. Distribution It is found throughout Europe, in Algeria, in western Asia and through the Palearctic to Siberia, China, and Japan. Technical description Forewing rufous ochreous tinged with purplish and mixed with ol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ranunculaceae
Ranunculaceae (buttercup or crowfoot family; Latin "little frog", from "frog") is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide. The largest genera are ''Ranunculus'' (600 species), ''Delphinium'' (365), ''Thalictrum'' (330), ''Clematis'' (325), and ''Aconitum'' (300). Description Ranunculaceae are mostly herbaceous annuals or perennials, but some are woody climbers (such as ''Clematis'') or shrubs (e.g. ''Xanthorhiza''). Most members of the family have bisexual flowers which can be showy or inconspicuous. Flowers are solitary, but are also found aggregated in cymes, panicles, or spikes. The flowers are usually radially symmetrical but are also found to be bilaterally symmetrical in the genera ''Aconitum'' and ''Delphinium''. The sepals, petals, stamens and carpels are all generally free (not fused), the outer flower segments typically number four or five. The outer stamens may be modified to produce only nectar, as in Aqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of The Largest Genera Of Flowering Plants
There are over 56 genera of flowering plants estimated to contain at least 500 described species. The largest of these is currently the legume genus '' Astragalus'' (milk-vetches), with over 3,000 species. The sizes of plant genera vary widely from those containing a single species to genera containing thousands of species, and this disparity became clear early in the history of plant classification. The largest genus in Carl Linnaeus' seminal ''Species Plantarum'' was ''Euphorbia'', with 56 species; Linnaeus believed that no genus should contain more than 100 species. Part of the disparity in genus sizes is attributable to historical factors. According to a hypothesis published by Max Walters in 1961, the size of plant genera is related to the age, not of the taxon itself, but of the concept of the taxon in the minds of taxonomists. Plants which grew in Europe, where most of the early taxonomy was based, were therefore divided into relatively small genera, while those from the ...

Northern Europe
The northern region of Europe has several definitions. A restrictive definition may describe Northern Europe as being roughly north of the southern coast of the Baltic Sea, which is about 54°N, or may be based on other geographical factors such as climate and ecology. Climate The climate is mainly Oceanic climate (Cfb), Humid continental climate (Dfb), Subarctic climate (Dfc and Dsc) and Tundra (ET). Geography Northern Europe might be defined roughly to include some or all of the following areas: British Isles, Fennoscandia, the peninsula of Jutland, the Baltic plain that lies to the east and the many islands that lie offshore from mainland Northern Europe and the main European continent. In some cases, Greenland is also included, although it is only politically European, comprising part of the Kingdom of Denmark, and not considered to be geographically in Europe. The area is partly mountainous, including the northern volcanic islands of Iceland and Jan Mayen, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
