Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life 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 generally white or yellowish (orange or red in garden kinds), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten portions with roughly 50 species. The true variety of varieties has mixed, depending about how they are categorized, due to similarity between hybridization and kinds. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origins of the name Narcissus is mysterious, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The species 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 released 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, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while others 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 overdue 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as slice blossoms as ornamental plant life in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. 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 skill, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as symbols of spring and coil. The daffodil is the countrywide blossom of Wales and the image of cancer charities in many countries. The looks of the outdoors 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 for an underground storage light bulb. They regrow in the next year from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The plants are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the light bulb. The herb stem usually bears a solitary flower, but sometimes a cluster of flowers (umbel). The bouquets, that are usually conspicuous and white or yellow, both or hardly ever inexperienced sometimes, consist of 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 designed corona. The bouquets may hang down (pendent), or be erect. There are six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries contains a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb lays dormant following the leaves and blossom stem die back and has contractile root base that move it down further into the soil. The bloom leaves and stem form in the light, to emerge the next season. Most kinds are dormant from warmer summer months to past due winter, flowering in the spring, though a few kinds are autumn flowering.
