Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The bouquets are generally white or yellow (orange or green in garden kinds), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in historic civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten areas with about 50 species. The number of varieties has assorted, depending about how they are categorized, a consequence of 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 origins of the name Narcissus is unidentified, but it is often associated with a Greek term for intoxicated (narcotic) and the misconception of the youth of that name who fell deeply in love with his own reflection. The English word 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The kinds are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East 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 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 after the 16th century and by the late 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as cut plants so that ornamental plant life in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of colours and shapes. Like other members of the family, narcissi create 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to fortune, and as icons of springtime. The daffodil is the nationwide rose of Wales and the image of tumors charities in many countries. The appearance of the outrageous 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 to a underground storage light bulb. They regrow in the next yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might increase as high as 80 cm.
The vegetation are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light bulb. The flower stem bears a solitary bloom, but occasionally a cluster of flowers (umbel). The plants, which are conspicuous and white or yellow usually, both or hardly ever inexperienced sometimes, consist of 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 disc to conical shaped corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb sits dormant after the leaves and flower stem die back and has contractile origins that move it down further into the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most varieties are dormant from summer season to overdue winter, flowering in the springtime, though a few species are autumn flowering.
