Daffodil
''Narcissus'' is a genus of predominantly spring flowering perennial plants of the amaryllis family, Amaryllidaceae. Various common names including daffodil,The word "daffodil" is also applied to related genera such as ''Sternbergia'', ''Ismene'' and ''Fritillaria meleagris''. It has been suggested that the word "Daffodil" be restricted to the wild species of the British Isles, '' N. pseudonarcissus''. narcissus, and jonquil are used to describe all or some members of the genus. ''Narcissus'' has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The flowers are generally white and yellow (also orange or pink in garden varieties), with either uniform or contrasting coloured tepals and corona. ''Narcissus'' were well known in ancient civilisation, both medicinally and botanically, but formally described by Linnaeus in his ''Species Plantarum'' (1753). The genus is generally considered to have about ten sections with approximately 50 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amaryllidaceae
The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous (rarely rhizomatous) flowering plants in the monocot order Asparagales. The family takes its name from the genus '' Amaryllis'' and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae). The family, which was originally created in 1805, now contains about 1600 species, divided into about 70–75 genera, 17 tribes and three subfamilies, the Agapanthoideae (agapanthus), Allioideae (onions and chives) and Amaryllidoideae ( amaryllis, daffodils, snowdrops). Over time, it has seen much reorganisation and at various times was combined with the related Liliaceae. Since 2009, a ver ...

Narcissus (mythology)
In Greek mythology, Narcissus (; Ancient Greek: Νάρκισσος ''Nárkissos'') was a hunter from Thespiae in Boeotia (alternatively Mimas or modern day Karaburun, Izmir) who was known for his beauty. According to Tzetzes, he rejected all romantic advances, eventually falling in love with his own reflection in a pool of water, staring at it for the remainder of his life. After he died, in his place sprouted a flower bearing his name. The character of Narcissus is the origin of the term narcissism, a fixation with oneself. This quality, in turn, contributes to the definition of narcissistic personality disorder, a psychiatric condition marked by grandiosity, excessive need for attention and admiration, and an inability to empathize. Like the myth of Laius and Chrysippus, the myth of Narcissus is a Boeotian pederastic cautionary tale, a story meant to teach by counter-example. Etymology The name is of Greek etymology.

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in '' Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated var ...

Fritillaria Meleagris
''Fritillaria meleagris'' is a Eurasian species of flowering plant in the lily family Liliaceae. Its common names include snake's head fritillary, snake's head (the original English name), chess flower, frog-cup, guinea-hen flower, guinea flower, leper lily (because its shape resembled the bell once carried by lepers), Lazarus bell, chequered lily, chequered daffodil, drooping tulip or, in the British Isles, simply fritillary. The plant is a bulbous perennial native to the flood river plains of Europe where it grows in abundance. Etymology The Latin binomial nomenclature, specific epithet ''meleagris'' means "spotted like a guineafowl". The common name "snake's head" probably refers to the somewhat snakelike appearance of the nodding flower heads, especially when in bud, on their long stems. Description and habitat The flower has a chequered pattern in shades of purple, or is sometimes pure white. It flowers from March to May and grows between in height. The plant has a button ...

Ismene (plant)
''Ismene'', or Peruvian daffodil, is a genus of South American plants in the Amaryllis family. The species are native to Peru and Ecuador and widely cultivated elsewhere as ornamentals because of their large, showy flowers. ''Ismene'' produces tender perennial bulbs bearing a strong resemblance to those of ''Hymenocallis'', a genus into which ''Ismene'' had often been grouped in the past. However, its morphology differs from ''Hymenocallis'' in several significant ways: its vegetative parts, natural range, and chromosome number are all distinct. ''Ismene'' can be difficult to grow in the United States.Howard, Thad M. ''Bulbs for Warm Climates''. Austin, Texas: University of Texas Press, 2001, pp 98–99. Species A list of ''Ismene'' species and their geographic distribution is given below. *'' Ismene amancaes'' (Ruiz & Pav.)

Sternbergia
''Sternbergia'' is a genus of Eurasian and North African plants in the Amaryllis family, subfamily Amaryllidoideae.Waldstein, Franz de Paula Adam von & Kitaibel, Pál. 1804. Descriptiones et Icones Plantarum Rariorum Hungariae 2: 172 The genus comprises eight recognised species that show a broad distribution throughout the Mediterranean Basin as well as central and southwestern Asia. ''Sternbergia'' contains a number of species of flowering bulbs which rather resemble ''Crocus''. These plants produce golden-yellow goblet-shaped flowers borne on stalks some way above the ground that open during the autumn or early winter. The flower is composed of six stamens and a single style attached to an inferior ovary. Long, strap-like leaves may appear with the flowers or sometime after. The only two exceptions to this are '' S. vernalis'' and '' S. candida'' which flower in the spring, with ''S. candida'' producing striking white flowers. The genus has gained notability due to the wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galantamine
Galantamine is used for the treatment of cognitive decline in mild to moderate Alzheimer's disease and various other memory impairments. It is an alkaloid that has been isolated from the bulbs and flowers of '' Galanthus nivalis'' (Common snowdrop), ''Galanthus caucasicus'' (Caucasian snowdrop), ''Galanthus woronowii'' (Voronov's snowdrop), and some other members of the family '' Amaryllidaceae'', such as ''Narcissus'' (daffodil), '' Leucojum aestivum'' (snowflake), and ''Lycoris'' including '' Lycoris radiata'' (red spider lily). It can also be produced synthetically. Studies of usage in modern medicine began in the Soviet Union in the 1950s. Galantamine was isolated for the first time from bulbs of '' Galanthus nivalis'' (common snowdrop) by the Bulgarian chemist D. Paskov and his team in 1956. The active ingredient was extracted, identified, and studied, in particular in relation to its acetylcholinesterase (AChE)-inhibiting properties. The first industrial process was d ...

Floral Morphology Narcissus
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 positi ... [...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] |
Narcotic
The term narcotic (, from ancient Greek ναρκῶ ''narkō'', "to make numb") originally referred medically to any psychoactive compound with numbing or paralyzing properties. In the United States, it has since become associated with opiates and opioids, commonly morphine and heroin, as well as derivatives of many of the compounds found within raw opium latex. The primary three are morphine, codeine, and thebaine (while thebaine itself is only very mildly psychoactive, it is a crucial precursor in the vast majority of semi-synthetic opioids, such as oxycodone or hydrocodone). Legally speaking, the term "narcotic" may be imprecisely defined and typically has negative connotations. When used in a legal context in the U.S., a narcotic drug is totally prohibited, such as heroin, or one that is used in violation of legal regulation (in this word sense, equal to any controlled substance or illicit drug). In the medical community, the term is more precisely defined and gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
