Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common titles 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 the cup- or trumpet-shaped corona. The blooms are usually white or yellow (orange or green in garden types), with either uniform or contrasting colored tepals and corona.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten sections with about 50 species. The true range of varieties has assorted, depending about how they are categorized, thanks to similarity between hybridization and types. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the true name Narcissus is mysterious, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the youth of that name who fell in love with his own representation. The English expression 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The kinds are local to meadows and woods in southern Europe and North Africa with a centre of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East prior to the tenth century. Narcissi tend 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 become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the past due 19th century were an important commercial crop centred primarily on holland. Narcissi are popular as slice blossoms and as ornamental crops in private and general population gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of colours and shapes. Like other members with their 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 resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in various cultures, ranging from fatality to fortune, and as icons of springtime. The daffodil is the national blossom of Wales and the symbol of tumor charities in many countries. The appearance of the crazy 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 with an underground storage bulb. They regrow in the following calendar year 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 height of 5-8 cm, while Narcissus tazetta might expand as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, slim, strap-shaped leaves occur from the bulb. The herb stem bears a solitary rose, but sometimes a cluster of blossoms (umbel). The blossoms, that happen to be conspicuous and white or yellow usually, both or almost never inexperienced sometimes, contain 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 blooms may suspend down (pendent), or be erect. There are six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The fruits consists of a dry capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant after the leaves and blossom stem die back and has contractile root base that pull it down further in to the soil. The flower stem and leaves form in the light bulb, to emerge the next season. Most varieties are dormant from summer season to overdue winter, flowering in the springtime, though a few species are autumn flowering.
