Narcissus Define Narcissus at Dictionary.com

Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 way of a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or pink in garden varieties), with either uniform or contrasting coloured corona and tepals.

Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten parts with around 50 species. The true number of types has assorted, depending about how they are categorised, anticipated to similarity between types and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the real name Narcissus is undiscovered, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the children of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.

The types are native to meadows and woods in southern European countries and North Africa with a center of diversity in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were presented in to the ASIA to the tenth century 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 become extinct, while others 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 late 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as chop plants and as ornamental crops in private and general public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a variety of colours and shapes. 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 accidentally ingested. 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 literature and art work, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as symbols of spring and coil. The daffodil is the national rose of Wales and the icon of cancers charities in many countries. The looks of the outdoors flowers in springtime is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage bulb. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as extra tall as 80 cm.

The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves come up from the light. The flower stem usually bears a solitary bloom, but occasionally a cluster of bouquets (umbel). The flowers, which can be usually conspicuous and white or yellow, sometimes both or hardly ever green, 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 disk to conical shaped corona. The plants may hang up down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried up capsule that splits (dehisces) releasing numerous black seed products.

The bulb lies dormant after the leaves and flower stem die again and has contractile origins that draw it down further in to the soil. The flower leaves and stem form in the light bulb, to emerge the following season. Most kinds are dormant from summer to past due winter, flowering in the spring, though a few species are autumn flowering.
