Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 generally white or yellow (orange or pink in garden varieties), with either even or contrasting colored corona and tepals.
Narcissus were popular in early civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten sections with roughly 50 species. The true amount of types has varied, depending about how they are categorized, due to similarity between kinds and hybridization. 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 name Narcissus is anonymous, but it is associated with a Greek term for intoxicated (narcotic) and the myth of the junior of this name who fell deeply in love with his own representation. The English expression 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The kinds are local to meadows and woods in southern Europe and North Africa with a centre of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were unveiled 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 insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. 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 after the 16th century and by the later 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as slice flowers so when ornamental plants 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 labeled into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi create a true 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 use in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as symbols of planting season. The daffodil is the nationwide rose of Wales and the sign of tumors 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 to the underground storage light bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach heights 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 expand as extra tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several blue-green or green, slim, strap-shaped leaves occur from the light bulb. The place stem usually bears a solitary blossom, but occasionally a cluster of blossoms (umbel). The flowers, that are usually conspicuous and white or yellow, both or hardly ever green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The blossoms may hang down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The berries contains a dry out capsule that splits (dehisces) launching numerous black seeds.
The bulb is dormant after the leaves and flower stem die back and has contractile roots that yank it down further into the soil. The rose stem and leaves form in the light, to emerge the next season. Most kinds are dormant from summer time to late winter, flowering in the planting season, though a few kinds are autumn flowering.
