Artichoke
The globe artichoke ('' Cynara cardunculus'' var. ''scolymus'' ),Rottenberg, A., and D. Zohary, 1996: "The wild ancestry of the cultivated artichoke." Genet. Res. Crop Evol. 43, 53–58. also known by the names French artichoke and green artichoke in the U.S., is a variety of a species of thistle cultivated as food. The edible portion of the plant consists of the flower buds before the flowers come into bloom. The budding artichoke flower-head is a cluster of many budding small flowers (an inflorescence), together with many bracts, on an edible base. Once the buds bloom, the structure changes to a coarse, barely edible form. Another variety of the same species is the cardoon, a perennial plant native to the Mediterranean region. Both wild forms and cultivated varieties (cultivars) exist. Description This vegetable grows to tall, with arching, deeply lobed, silvery, glaucous-green leaves long. The flowers develop in a large head from an edible bud about diameter with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cynara Cardunculus
The cardoon, ''Cynara cardunculus'' (), also called the artichoke thistle, is a thistle in the family Asteraceae. It is a naturally occurring species that also has many cultivated forms, including the globe artichoke. It is native to the western and central Mediterranean region, where it was domesticated in ancient times and still occurs as a wild plant. Description The wild cardoon is a stout herbaceous perennial plant growing tall, with deeply lobed and heavily spined green to grey-green tomentose (hairy or downy) leaves up to long, with yellow spines up to 3.5 cm long. The flowers are violet-purple, produced in a large, globose, massively spined capitulum up to in diameter.Tela Botanica: ''Cynara cardunculus'' L. (in French)Huxley, A., ed. (1992). ''New RHS Dic ...

Phono-semantic Matching
Phono-semantic matching (PSM) is the incorporation of a word into one language from another, often creating a neologism, where the word's non-native quality is hidden by replacing it with Phonetics, phonetically and semantically similar words or roots from the adopting language. Thus the approximate sound and meaning of the original expression in the source language are preserved, though the new expression (the PSM – the phono-semantic match) in the target language may sound native. Phono-semantic matching is distinct from calquing, which includes (semantic) translation but does not include phonetic matching (i.e., retention of the approximate sound of the borrowed word through matching it with a similar-sounding pre-existent word or morpheme in the target language). Phono-semantic matching is also distinct from homophonic translation, which retains the sound of a word but not the meaning. History The term "phono-semantic matching" was introduced by linguist and revivalis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thistle
Thistle is the common name of a group of flowering plants characterised by leaves with sharp prickles on the margins, mostly in the family Asteraceae. Prickles can also occur all over the planton the stem and on the flat parts of the leaves. These prickles are an adaptation that protects the plant from being eaten by herbivores. Typically, an involucre with a clasping shape similar to a cup or urn subtends each of a thistle's flower heads. The comparative amount of spininess varies dramatically by species. For example, ''Cirsium heterophyllum'' has minimal spininess while '' Cirsium spinosissimum'' is the opposite. Typically, species adapted to dry environments have greater spininess. The term thistle is sometimes taken to mean precisely those plants in the tribe Cardueae (synonym: Cynareae), especially the genera '' Carduus'', '' Cirsium'', and '' Onopordum''. However, plants outside this tribe are sometimes called thistles. Biennial thistles are particularly notewor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cynarine
Cynarine is a hydroxycinnamic acid derivative and a biologically active chemical constituent of artichoke (''Cynara cardunculus''). Chemically, it is an ester formed from quinic acid Quinic acid is a cyclitol, a cyclic polyol, and a cyclohexanecarboxylic acid. It is a colorless solid that can be extracted from plant sources.

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positione ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luteolin
Luteolin is a flavone, a type of flavonoid, with a yellow crystalline appearance. Luteolin is the principal yellow dye compound that is obtained from the plant ''Reseda luteola'', which has been used as a source of the dye since at least the first millennium B.C. Luteolin was first isolated in pure form, and named, in 1829 by the French chemist Michel Eugène Chevreul. The luteolin empirical formula was determined by the Austrian chemists Heinrich Hlasiwetz and Leopold Pfaundler in 1864. In 1896, the English chemist Arthur George Perkin proposed the correct structure for luteolin. Perkin's proposed structure for luteolin was confirmed in 1900 when the Polish-Swiss chemist Stanislaw Kostanecki (1860–1910) and his students A. Różycki and J. Tambor synthesized luteolin. Natural occurrences Luteolin is most often found in leaves, but it is also seen in rinds, barks, clover blossom, and ragweed pollen. It has also been isolated from the aromatic flowering plant, ''Salvia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modern Standard Arabic
Modern Standard Arabic (MSA) or Modern Written Arabic (MWA), terms used mostly by linguists, is the variety of standardized, literary Arabic that developed in the Arab world in the late 19th and early 20th centuries; occasionally, it also refers to spoken Arabic that approximates this written standard. MSA is the language used in literature, academia, print and mass media, law and legislation, though it is generally not spoken as a first language, similar to Contemporary Latin. It is a pluricentric standard language taught throughout the Arab world in formal education, differing significantly from many vernacular varieties of Arabic that are commonly spoken as mother tongues in the area; these are only partially mutually intelligible with both MSA and with each other depending on their proximity in the Arabic dialect continuum. Many linguists consider MSA to be distinct from Classical Arabic (CA; ) – the written language prior to the mid-19th century – althou ...

Scale (anatomy)
In most biological nomenclature, a scale ( grc, λεπίς, lepís; la, squāma) is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopteran (butterfly and moth) species, scales are plates on the surface of the insect wing, and provide coloration. Scales are quite common and have evolved multiple times through convergent evolution, with varying structure and function. Scales are generally classified as part of an organism's integumentary system. There are various types of scales according to shape and to class of animal.

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