Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or red in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten parts with around 50 species. The true variety of kinds has varied, depending how they are labeled, due to similarity between hybridization and kinds. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origins of the real name Narcissus is undiscovered, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The types are native to meadows and woods in southern European countries and North Africa with a centre of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the late 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as slash flowers and since ornamental crops in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members of their 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 treating Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a number of themes in several cultures, ranging from death to good fortune, and as icons of springtime. The daffodil is the national flower of Wales and the mark of tumor 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 after flowering to a underground storage light. They regrow in the next calendar year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum level 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 flower stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the bulb. The seed stem bears a solitary rose, but occasionally a cluster of flowers (umbel). The blooms, that are conspicuous and white or yellowish usually, both or almost never renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The flowers may hang down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dry out capsule that splits (dehisces) launching numerous black seed products.
The bulb is situated dormant following the leaves and blossom stem die again and has contractile root base that pull it down further into the soil. The bloom leaves and stem form in the light, to emerge the next season. Most types are dormant from summer season to late winter, flowering in the springtime, though a few types are autumn flowering.
