Narcissus /n?:r's?s?s/ is a genus of predominantly 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 a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or green in garden kinds), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten portions with approximately 50 species. The true variety of kinds has varied, depending on how they are categorised, as a consequence to similarity between hybridization and species. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the name Narcissus is anonymous, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own reflection. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The varieties are native to meadows and woods in southern Europe and North Africa with a center of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were released in to 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 urbanisation and tourism.
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 century were an important commercial crop centred mainly on holland. Today narcissi are popular as cut bouquets as ornamental vegetation in private and public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety 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 ingested accidentally. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a number of themes in several cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the national flower of Wales and the sign of cancer tumor charities in many countries. The appearance of the outrageous flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage bulb. They regrow in the next yr 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 level of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, thin, strap-shaped leaves happen from the light bulb. The herb stem usually bears a solitary flower, but sometimes a cluster of flowers (umbel). The flowers, that are conspicuous and white or yellowish usually, sometimes both or almost never green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The plants may suspend down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries contains a dried up capsule that splits (dehisces) liberating numerous black seeds.
The bulb is situated dormant after the leaves and flower stem die back and has contractile root base that move it down further in to the soil. The flower leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from warmer summer months to overdue winter, flowering in the planting season, though a few varieties are autumn flowering.
