Narcissus /n?:r's?s?s/ is a genus of mainly 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or green in garden kinds), with either even or contrasting coloured tepals and corona.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten sections with around 50 species. The true number of types has assorted, depending how they are grouped, as a consequence to similarity between hybridization and varieties. 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 real name Narcissus is unfamiliar, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The varieties are indigenous to meadows and woods in southern European countries and North Africa with a centre of variety in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi tend 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 grown to be 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 hundred years and by the later 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as lower plants so when ornamental plant life in private and 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 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 use in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a true number of themes in several cultures, ranging from fatality to good fortune, and as icons of spring and coil. The daffodil is the nationwide blossom of Wales and the icon of cancers charities in many countries. The looks of the outrageous flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage bulb. They regrow in the following year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light. The herb stem usually bears a solitary blossom, but occasionally a cluster of blossoms (umbel). The blossoms, that are conspicuous and white or yellow usually, both or seldom green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The bouquets may hang down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries includes a dried up capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant following the leaves and rose stem die back and has contractile origins that draw it down further into the soil. The blossom leaves and stem form in the light, to emerge the following season. Most species are dormant from summertime to late winter, flowering in the springtime, though a few kinds are fall flowering.
