Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or pink in garden varieties), with either standard or contrasting colored tepals and corona.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten parts with roughly 50 species. The true range of kinds has assorted, depending about how they are categorized, scheduled to similarity between types and hybridization. The genus arose 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 undiscovered, but it is associated with a Greek expression for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the Western Mediterranean, particularly the Iberian peninsula. 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 become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the late 19th century were an important commercial crop centred generally on holland. Narcissi are popular as chop flowers so when ornamental vegetation in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of colours and shapes. Like other members of their family, narcissi create 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 within traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a true number of themes in various cultures, ranging from death to fortune, and as icons of spring. The daffodil is the national flower of Wales and the sign of cancers charities in many countries. The looks of the wild flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light. They regrow in the following time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as high as 80 cm.
The plant life are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, thin, strap-shaped leaves occur from the bulb. The seed stem bears a solitary rose, but sometimes a cluster of plants (umbel). The blossoms, that are usually conspicuous and white or yellowish, sometimes both or seldom green, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruits includes a dry capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and blossom stem die again and has contractile origins that pull it down further in to the soil. The rose leaves and stem form in the light, to emerge the next season. Most kinds are dormant from summer months to later winter, flowering in the springtime, though a few types are fall months flowering.
