Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 by the cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or pink in garden kinds), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in historical civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten parts with roughly 50 species. The true range of kinds has mixed, depending on how they are labeled, due to similarity between hybridization and kinds. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is unidentified, but it is often linked to a Greek phrase for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own representation. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East to the tenth hundred years prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th hundred years and by the later 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as lower plants so that ornamental vegetation in private and general population gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of colours and shapes. Like other members of the family, narcissi create a 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 used in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a true number of themes in various cultures, ranging from fatality to good fortune, and as symbols of spring. The daffodil is the nationwide flower of Wales and the symbol of cancer charities in many countries. The looks of the untamed flowers in spring is associated with festivals 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 next time from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the light bulb. The flower stem bears a solitary bloom, but occasionally a cluster of blossoms (umbel). The flowers, that are conspicuous and white or yellowish usually, sometimes both or seldom inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The flowers may suspend down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries contains a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant following the leaves and blossom stem die back and has contractile origins that pull it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the next season. Most types are dormant from summer time to later winter, flowering in the spring and coil, though a few species are autumn flowering.
