Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or green in garden varieties), with either standard or contrasting coloured corona and tepals.
Narcissus were well known in old civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten areas with about 50 species. The amount of species has assorted, depending how they are labeled, a consequence of to similarity between hybridization and varieties. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the name Narcissus is unidentified, but it is linked to a Greek word for intoxicated (narcotic) and the myth of the youth of this name who fell in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The kinds are native to meadows and woods in southern Europe and North Africa with a centre of variety in the American Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the late 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as slice blossoms so that ornamental vegetation in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range of colours and shapes. Like other members of the family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if accidentally ingested. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art work, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the countrywide rose of Wales and the symbol of cancers charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light bulb. They regrow in the following calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as extra tall as 80 cm.
The plants are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, thin, strap-shaped leaves come up from the light bulb. The flower stem usually bears a solitary rose, but sometimes a cluster of blossoms (umbel). The flowers, that happen to be usually conspicuous and white or yellowish, both or almost never inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blossoms may hang up down (pendent), or be erect. You will discover six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The super fruit consists of a dried out capsule that splits (dehisces) liberating numerous black seeds.
The bulb is situated dormant after the leaves and flower stem die back again and has contractile root base that draw it down further into the soil. The rose leaves and stem form in the light, to emerge the next season. Most species are dormant from summer season to late winter, flowering in the springtime, though a few kinds are fall months flowering.
Most prostate cancers are adenocarcinomas, cancers that arise in glandular cells of the prostate’s epithelial tissue. Prostate cancers usually progress slowly and produce no symptoms in the initial stages. Eventually, the tumor may enlarge like mine use too, the prostate gland, pressing on the urethra and causing painful or frequent urination and blood in the urine.
