Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants 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 green in garden types), with either uniform or contrasting coloured corona and tepals.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally defined by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten parts with approximately 50 species. The number of kinds has mixed, depending on how they are categorized, due to similarity between hybridization and kinds. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source 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 in love with his own reflection. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The types are local to meadows and woods in southern European countries and North Africa with a middle of variety in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were launched into the Far East to the tenth hundred years prior. Narcissi tend 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, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe following the 16th century and by the late 19th hundred years were an important commercial crop centred generally on holland. Today narcissi are popular as slash blossoms so when ornamental crops in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of shapes and colours. 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 unintentionally. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in various cultures, ranging from death to good fortune, and as symbols of springtime. The daffodil is the countrywide blossom of Wales and the mark of malignancy charities in many countries. The appearance of the untamed flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage light. They regrow in the following time from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the light. The flower stem bears a solitary bloom, but once in a while a cluster of blooms (umbel). The blossoms, that are conspicuous and white or yellowish usually, sometimes both or rarely inexperienced, 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 formed corona. The blossoms may suspend down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb is placed dormant after the leaves and rose stem die back and has contractile root base that yank it down further in to the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most varieties are dormant from warmer summer months to late winter, flowering in the springtime, though a few species are fall flowering.
