Narcissus odorus Specie della flora italiana

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

Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten portions with around 50 species. The amount of kinds has assorted, depending how they are categorized, thanks to similarity between hybridization and species. 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 source of the name Narcissus is undiscovered, but it is associated with a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of that name who fell deeply in love with his own representation. The English expression 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.

The kinds are local to meadows and woods in southern Europe and North Africa with a centre of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi have a tendency 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, mites and nematodes. Some Narcissus species have grown to be extinct, while others are threatened by increasing tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as chop flowers and as ornamental plants 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 of their family, narcissi create 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 utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and literature, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as symbols of spring. The daffodil is the countrywide flower of Wales and the mark of cancer charities in many countries. The appearance of the crazy flowers in spring is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage bulb. They regrow in the following calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as large as 80 cm.

The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the bulb. The vegetable stem usually bears a solitary blossom, but once in a while a cluster of plants (umbel). The plants, that are usually conspicuous and white or yellowish, both or rarely renewable sometimes, 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 molded corona. The flowers may hang down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries contains a dried out capsule that splits (dehisces) releasing numerous black seeds.

The bulb is placed dormant after the leaves and rose stem die again and has contractile origins that draw it down further into the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from summer to late winter, flowering in the spring, though a few varieties are fall flowering.
