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 by the cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or pink in garden varieties), with either standard or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten portions with approximately 50 species. The true range of species has mixed, depending about how they are categorised, scheduled to similarity between varieties and hybridization. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the name Narcissus is unfamiliar, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The species 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 in to the ASIA 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, diseases and disorders 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 earliest times, but became increasingly popular in Europe following the 16th hundred years and by the later 19th century were an important commercial crop centred primarily on holland. Narcissi are popular as trim blooms and as ornamental vegetation in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members of these family, narcissi create a 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 utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as symbols of spring. The daffodil is the nationwide blossom of Wales and the symbol of cancer charities in many countries. The looks of the crazy flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to the underground storage light bulb. They regrow in the next yr from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves arise from the light bulb. The place stem usually bears a solitary rose, but once in a while a cluster of bouquets (umbel). The blossoms, that are conspicuous and white or yellowish usually, sometimes both or seldom renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The flowers may hang up down (pendent), or be erect. A couple of six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry contains a dried out capsule that splits (dehisces) releasing numerous black seed products.
The bulb is situated dormant after the leaves and blossom stem die back again and has contractile root base that draw it down further into the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most species are dormant from summer season to overdue winter, flowering in the springtime, though a few types are autumn flowering.
