Convolvulus Sepium
''Calystegia sepium'' (hedge bindweed, Rutland beauty, bugle vine, heavenly trumpets, bellbind, granny-pop-out-of-bed and many others) is a species of flowering plant in the family Convolvulaceae. It has a subcosmopolitan distribution throughout temperate regions of the North and South hemispheres. Description It is an herbaceous perennial that twines around other plants, in a counter-clockwise direction, to a height of up to , rarely . The pale matte green leaves are arranged spirally, simple, pointed at the tip and are arrowhead shaped, long and broad. The flowers are white, or pale pink with five darker stripes, produced from late spring to the end of summer. In the UK, between July and September. In the bud, they are covered by large green but tinged with crimson bracts which remain but scarcely overlap and do not cover the sepals of the open flower. The open flowers are trumpet-shaped, diameter, white, or pale pink with white stripes. After flowering, the fruit develops ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calystegia Silvatica Bracteoles
''Calystegia'' (bindweed, false bindweed, or morning glory) is a genus of about 25 species of flowering plants in the bindweed family Convolvulaceae. The genus has a cosmopolitan distribution in temperate and subtropical regions, but with half of the species endemic to California. They are annual or herbaceous perennial twining vines growing 1–5 m tall, with spirally arranged leaves. The flowers are trumpet-shaped, 3–10 cm diameter, white or pink, with (in most species) a sometimes inflated basal epicalyx. The genus bears much similarity to a related genus ''Convolvulus'', and is sometimes combined with it; it is distinguished primarily by the pollen being smooth, and in the ovary being unilocular. Some of the species, notably ''Calystegia sepium'' and '' C. silvatica'', are problematic weeds, which can swamp other more valuable plants by climbing over them, but some are also deliberately grown for their attractive flowers. ''Calystegia'' species are eaten by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poems Of Letitia Elizabeth Landon (L
Poetry (derived from the Greek ''poiesis'', "making"), also called verse, is a form of literature that uses aesthetic and often rhythmic qualities of language − such as phonaesthetics, sound symbolism, and metre − to evoke meanings in addition to, or in place of, a prosaic ostensible meaning. A poem is a literary composition, written by a poet, using this principle. Poetry has a long and varied history, evolving differentially across the globe. It dates back at least to prehistoric times with hunting poetry in Africa and to panegyric and elegiac court poetry of the empires of the Nile, Niger, and Volta River valleys. Some of the earliest written poetry in Africa occurs among the Pyramid Texts written during the 25th century BCE. The earliest surviving Western Asian epic poetry, the ''Epic of Gilgamesh'', was written in Sumerian. Early poems in the Eurasian continent evolved from folk songs such as the Chinese ''Shijing'', as well as religious hymns (the Sanskrit ' ...

Ipomoea Pandurata
''Ipomoea pandurata'', known as man of the earth, wild potato vine, manroot, wild sweet potato, and wild rhubarb, is a species of herbaceous perennial vine native to North America. It is a twining plant of woodland verges and rough places with heart-shaped leaves and funnel-shaped white flowers with a pinkish throat. The large tuberous roots can be roasted and eaten, or can be used to make a poultice or infusion. When uncooked, the roots have purgative properties.Peterson, Lee, ''A Field Guide to Edible Wild Plants of Eastern and Central North America'', p. 20, Houghton Mifflin Company, New York City, accessed 22 November 2010. Description ''I. pandurata'' is a twining and scrambling vine that can reach . The stems are usually hairless and bear alternate, olive-green, cordate leaves, about long, with long, purple-tinged petioles. The flowers develop in the axils of the leaves in groups of one to five. The sepals are light green and hairless, and overlap one another. The flowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convolvulus Arvensis
''Convolvulus arvensis'', the field bindweed, is a species of bindweed that is rhizomatous and is in the morning glory family (Convolvulaceae), native to Europe and Asia. It is a climbing or creeping herbaceous perennial plant with stems growing to 0.5–2 metres in length, usually found at ground level, with small, white and pink flowers. Other common names, mostly obsolete, include lesser bindweed, European bindweed, withy wind (in basket willow crops), perennial morning glory, small-flowered morning glory, creeping jenny, and possession vine. Taxonomy This plant first gained its scientific name in 1753, when it was described by Linnaeus in the '' Species Plantarum''. In the centuries afterwards it gained many subspecies and varieties across its vast range, as well as synonyms as purportedly new species were described from places like China, Russia, Egypt or Morocco. New species and forms were even described from areas like Chile, Mexico and California when botanists enco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calystegia Silvatica
The morning glory ''Calystegia silvatica'' (syn. ''Calystegia sepium silvatica'', ''C. inflata'', and ''C. sylvestris'') is known by the common name giant bindweed or large bindweed. It is the largest species of bindweed and is a strong rampant climber. It is native to southern Europe but has been introduced to many other areas because it is an attractive garden plant. ''Calystegia silvatica'' subsp. ''fraterniflora'' (Mack. & Bush) Brummitt (short-stalked false bindweed) is native to North America. It has large, arrow-shaped leaves and showy white trumpet-shaped flowers up to 9 centimeters in diameter. It is considered a weed in some areas where it has escaped cultivation and now grows wild. It spreads easily via hardy rhizome In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow hori ...s. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glyphosate
Glyphosate (IUPAC name: ''N''-(phosphonomethyl)glycine) is a broad-spectrum Herbicide, systemic herbicide and Crop desiccation, crop desiccant. It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase. It is used to kill weeds, especially annual Forbs, broadleaf weeds and grasses that compete with crops. Its herbicidal effectiveness was discovered by Monsanto chemist John E. Franz in 1970. Monsanto brought it to market for agricultural use in 1974 under the trade name Roundup (herbicide), Roundup. Monsanto's last commercially relevant United States patent expired in 2000. Farmers quickly adopted glyphosate for agricultural weed control, especially after Monsanto introduced glyphosate-resistant Roundup Ready crops, enabling farmers to kill weeds without killing their crops. In 2007, glyphosate was the most used herbicide in the United States' agricultural sector and the second-most use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noxious Weed
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is injurious to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. Most noxious weeds have been introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native. Typically they are plants that grow aggressively, multiply quickly without natural controls (native herbivores, soil chemistry, etc.), and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forest management, nature reserves, parks and other open space. Many noxious weeds have come to new regions and countries through contaminated shipments of feed and crop seeds or were intentionally introduced as ornamental plants for horticultural use. Some "noxious weeds", such as ragwort, produce copious amou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
