Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops 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 by the cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or red in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were well known in old civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten sections with around 50 species. The amount of species has mixed, depending how they are classified, thanks to similarity between hybridization and kinds. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origin of the name Narcissus is mysterious, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the young ones of this name who fell deeply in love with his own representation. The English expression 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The varieties are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild 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 after the 16th hundred years and by the overdue 19th century were an important commercial crop centred primarily on holland. Narcissi are popular as slice flowers so that ornamental vegetation in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a wide range of shapes and colours. Like other members of these family, narcissi produce a true 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as symbols of spring. The daffodil is the countrywide blossom of Wales and the icon of cancer charities in many countries. The looks of the outdoors flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light. They regrow in the next time from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might grow as large as 80 cm.
The crops are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, narrow, strap-shaped leaves occur from the light. The plant stem usually bears a solitary bloom, but once in a while a cluster of flowers (umbel). The blooms, that are usually conspicuous and white or yellowish, both or almost never renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blossoms may hang up down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry involves a dry out capsule that splits (dehisces) liberating numerous black seeds.
The bulb lies dormant following the leaves and blossom stem die back again and has contractile root base that take it down further in to the soil. The flower leaves and stem form in the light, to emerge the next season. Most varieties are dormant from warmer summer months to later winter, flowering in the spring, though a few types are autumn flowering.
