Adonis Vernalis
''Adonis vernalis'', known variously as pheasant's eye, spring pheasant's eye, yellow pheasant's eye and false hellebore, is a perennial flowering plant in the buttercup family Ranunculaceae. It is found in dry meadows and steppes in Eurasia. More specifically, this plant grows in a wide range of locations which include open forests, forest clearings, dry meadows, mesic steppe, and mostly calcareous soil. Isolated populations are found from Spain in the west across Central Europe with fine examples in Valais, Switzerland, and southern Europe, reaching southern Sweden in the north and Abruzzo in the south, with its main area of distribution being the Pannonian Basin and the West Siberian Plain. In contrast to most other European ''Adonis'' species, the flowers appear in springtime, and are up to in diameter, with up to 20 bright yellow petals. Not only do the flowers begin to grow, but so do the plants aerial organs, from around April to May. The plant is poisonous, containing ca ...

Adonis (plant)
''Adonis'' is a genus of about 20–30 species of flowering plants of the crowfoot family, Ranunculaceae, native to Europe and Asia. The species grow to in height, with feathery, finely divided leaves. Their flowers are red, yellow or orange and have 5–30 petals. The Autumn Adonis, pheasant's-eye (''A. annua''), has flowers with bright red petals. The generic name ''Adonis'' refers to the mythical character Adonis, a lover of the goddess Aphrodite or Venus, and of Persephone, goddess of the underworld. Red flowers of the Adonis genus are said to have grown from the grave of Adonis, after he was slain by a wild boar possessed with unusual viciousness through instigation by the jealous Ares. According to the ''Metamorphoses'' of OvidOvid ''Metamorphoses'' X 519-741 the anemone, also of the family ''Ranunculaceae'', was created when Venus sprinkled nectar on his blood.

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] |
Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, 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 Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, 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. Sinc ...

List Of Poisonous Plants
Plants that produce toxins are referred to as poisonous plants. Plants that cause irritation on contact are also described as "poisonous". The toxins in poisonous plants affect herbivores, and deter them from consuming the plants. Plants cannot move to escape their predators, so they must have other means of protecting themselves from herbivorous animals. Some plants have physical defenses such as thorns, spines and prickles, but by far the most common type of protection is chemical. Over millennia, through the process of natural selection, plants have evolved the means to produce a vast and complicated array of chemical compounds to deter herbivores. Tannin, for example, is a defensive compound that emerged relatively early in the evolutionary history of plants, while more complex molecules such as polyacetylenes are found in younger groups of plants such as the Asterales. Many of the known plant defense compounds primarily defend against consumption by insects, though other a ... [...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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adonis Vernalis - Köhler–s Medizinal-Pflanzen-152
In Greek mythology, Adonis, ; derived from the Canaanite word ''ʼadōn'', meaning "lord". R. S. P. Beekes, ''Etymological Dictionary of Greek'', Brill, 2009, p. 23. was the mortal lover of the goddess Aphrodite. One day, Adonis was gored by a wild boar during a hunting trip and died in Aphrodite's arms as she wept. His blood mingled with her tears and became the anemone flower. Aphrodite declared the Adonia festival commemorating his tragic death, which was celebrated by women every year in midsummer. During this festival, Greek women would plant "gardens of Adonis", small pots containing fast-growing plants, which they would set on top of their houses in the hot sun. The plants would sprout, but soon wither and die. Then the women would mourn the death of Adonis, tearing their clothes and beating their breasts in a public display of grief. The Greeks considered Adonis's cult to be of Near Eastern origin. Adonis's name comes from a Canaanite word meaning "lord" and most mod ...
