Rumex Obtusifolius
''Rumex obtusifolius'', commonly known as bitter dock, broad-leaved dock, bluntleaf dock, dock leaf, dockens or butter dock, is a perennial plant in the family Polygonaceae. It is native to Europe, but is found on all temperate continents. It is a highly invasive species in some zones, resulting from its abundant seed dispersal, adaptability to reproduce, aggressive roots, ability to tolerate extreme climates, and hardiness. Etymology The name, ''Rumex obtusifolius'', was assigned by Carl Linnaeus in the 18th century, and has remained unchanged, although there are numerous subspecies. ''Rumex'' was Pliny's name for sorrel,Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 277, 335 while ''obtusifolius'' means 'obtuse-leaved' (obtuse + foliage). Description ''Rumex obtusifolius'' is a perennial herbaceous flowering plant that grows to a height of . It is easily recognizable by its very large oval leaves with cordate base ...

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] |
Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...

Acronicta Rumicis
''Acronicta rumicis'', the knot grass moth, is a species of moth which is part of the genus ''Acronicta'' and family Noctuidae. It was first described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae''. It is found in the Palearctic region. ''A. rumicis'' lives and feeds on plants located in wide-open areas. At its larval stage, as a caterpillar, it causes such a large impact as a crop pest that it has received much attention and research. ''A. rumicis'' feeds on maize, strawberries and other herbaceous plants. The moth's evolution has been affected by the industrial melanism that occurred in Europe during the late 19th and early 20th centuries, causing a dramatic increase in two aberrations (''salicin'' and ''lugubris''), which have darker grey wings. Today, ''A. rumicis'' is important to conservation efforts in the United Kingdom, because, like many other species, it is in decline. However, as it is part of a UK Priority Biodiversity Action Plan and receiving gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adam Bede
''Adam Bede'' was the first novel by Mary Ann Evans (George Eliot), and was published in 1859. It was published pseudonymously, even though Evans was a well-published and highly respected scholar of her time. The novel has remained in print ever since and is regularly used in university studies of 19th-century English literature. She described the novel as, “A country story full of the breath of cows and scent of hay”. Plot summary According to ''The Oxford Companion to English Literature'' (1967), : "the plot is founded on a story told to George Eliot by her aunt Elizabeth Evans, a Methodist preacher, and the original of Dinah Morris of the novel, of a confession of child-murder, made to her by a girl in prison." The novel follows the lives of four characters in the fictional community of Hayslope—a rural, pastoral, and close-knit community—in 1799. The novel revolves around a love "rectangle" among the beautiful but self-absorbed Hetty Sorrel; Captain Arthur Donnith ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Eliot
Mary Ann Evans (22 November 1819 – 22 December 1880; alternatively Mary Anne or Marian), known by her pen name George Eliot, was an English novelist, poet, journalist, translator, and one of the leading writers of the Victorian era. She wrote seven novels: ''Adam Bede'' (1859), ''The Mill on the Floss'' (1860), ''Silas Marner'' (1861), ''Romola'' (1862–63), ''Felix Holt, the Radical'' (1866), ''Middlemarch'' (1871–72) and '' Daniel Deronda'' (1876). Like Charles Dickens and Thomas Hardy, she emerged from provincial England; most of her works are set there. Her works are known for their realism, psychological insight, sense of place and detailed depiction of the countryside. ''Middlemarch'' was described by the novelist Virginia Woolf as "one of the few English novels written for grown-up people"Woolf, Virginia. "George Eliot." ''The Common Reader''.

Urtica Dioica
''Urtica dioica'', often known as common nettle, burn nettle, stinging nettle (although not all plants of this species sting) or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, it is now found worldwide, including New Zealand and North America. The species is divided into six subspecies, five of which have many hollow stinging hairs called trichomes on the leaves and stems, which act like hypodermic needles, injecting histamine and other chemicals that produce a stinging sensation upon contact ("contact urticaria", a form of contact dermatitis). The plant has a long history of use as a source for traditional medicine, food, tea, and textile raw material in ancient (such as Saxon) and modern societies. Description ''Urtica dioica'' is a dioecious, herbaceous, perennial plant, tall in the summer and dying down to the ground in winter. ...

Greek Cuisine
Greek cuisine (Greek: Ελληνική Κουζίνα) is the cuisine of Greece and the Greek diaspora. In common with many other cuisines of the Mediterranean, it is founded on the triad of wheat, olive oil, and wine. It uses vegetables, olive oil, grains, fish, and meat, including pork, poultry, veal and beef, lamb, rabbit, and goat. Other important ingredients include pasta (for example hilopites), cheeses, lemon juice, herbs, olives, and yogurt. Bread made of wheat is ubiquitous; other grains, notably barley, are also used, especially for paximathia. Common dessert ingredients include nuts, honey, fruits, and filo pastries. It continues traditions from Ancient Greek and Byzantine cuisine, while incorporating Balkan, Turkish and Italian influences. History Greek cuisine is part of the culture of Greece and is recorded in images and texts from ancient times. Its influence spread to ancient Rome and then throughout Europe and beyond. Ancient Greek cuisine was charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Romanian Cuisine
Romanian cuisine () is a diverse blend of different dishes from several traditions with which it has come into contact, but it also maintains its own character. It has been mainly influenced by Turkish and a series of European cuisines in particular from the Balkans, or Hungarian cuisine as well as culinary elements stemming from the cuisines of Central Europe. Romanian cuisine includes numerous holiday dishes arranged according to the mentioned season and holiday since the country has its roots in the Eastern Orthodox Church. Romanian dishes consist of vegetables, cereals, fruits, honey, milk, dairy products, meat and game. Multiple different types of dishes are available, which are sometimes included under a generic term; for example, the category '' ciorbă'' includes a wide range of soups with a characteristic sour taste. Variations include meat and vegetable soup, tripe (''ciorbă de burtă'') and calf foot soup, or fish soup, all of which are soured by lemon juice, sauer ...

Oxalic Acid
Oxalic acid is an organic acid with the systematic name ethanedioic acid and formula . It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water. Its name comes from the fact that early investigators isolated oxalic acid from flowering plants of the genus ''Oxalis'', commonly known as wood-sorrels. It occurs naturally in many foods. Excessive ingestion of oxalic acid or prolonged skin contact can be dangerous. Oxalic acid has much greater acid strength than acetic acid. It is a reducing agent and its conjugate base, known as oxalate (), is a chelating agent for metal cations. Typically, oxalic acid occurs as the dihydrate with the formula . History The preparation of salts of oxalic acid (crab acid) from plants had been known, at least since 1745, when the Dutch botanist and physician Herman Boerhaave isolated a salt from wood sorrel. By 1773, François Pierre Savary of Fribourg, Switzerland had isolated oxalic acid from i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinach
Spinach (''Spinacia oleracea'') is a leafy green flowering plant native to central and western Asia. It is of the order Caryophyllales, family Amaranthaceae, subfamily Chenopodioideae. Its leaves are a common edible vegetable consumed either fresh, or after storage using preservation techniques by canning, freezing, or dehydration. It may be eaten cooked or raw, and the taste differs considerably; the high oxalate content may be reduced by steaming. It is an annual plant (rarely biennial), growing as tall as . Spinach may overwinter in temperate regions. The leaves are alternate, simple, ovate to triangular, and very variable in size: long and broad, with larger leaves at the base of the plant and small leaves higher on the flowering stem. The flowers are inconspicuous, yellow-green, in diameter, and mature into a small, hard, dry, lumpy fruit cluster across containing several seeds. In 2018, world production of spinach was 26.3 million tonnes, with China alone accounti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seedling
A seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves). The two classes of flowering plants (angiosperms) are distinguished by their numbers of seed leaves: monocotyledons (monocots) have one blade-shaped cotyledon, whereas dicotyledons (dicots) possess two round cotyledons. Gymnosperms are more varied. For example, pine seedlings have up to eight cotyledons. The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons. The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule does not occur until the cotyledons have grown ab ...
