Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The blossoms are generally white or yellow (orange or pink in garden varieties), with either uniform or contrasting coloured corona and tepals.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten sections with about 50 species. The amount of species has varied, depending how they are grouped, a consequence of to similarity between hybridization and varieties. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the true name Narcissus is unknown, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the youth of this name who fell deeply in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The species are local to meadows and woods in southern European countries and North Africa with a centre of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. 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, nematodes and mites. Some Narcissus species have grown to be extinct, while some 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 following the 16th century and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Today narcissi are popular as cut blossoms so when ornamental plant life in private and general public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are labeled 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 accidentally ingested. This property has been exploited for medicinal used in traditional healing and has resulted in the production of galantamine for the treating 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 symbols of springtime. The daffodil is the national flower of Wales and the icon of cancers charities in many countries. The appearance of the outrageous flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering for an underground storage light bulb. They regrow in the following yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as tall as 80 cm.
The plants are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves come up from the light. The flower stem bears a solitary bloom, but sometimes a cluster of plants (umbel). The plants, which can be conspicuous and white or yellow usually, both or seldom renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blooms may hang up down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The super fruit consists of a dried out capsule that splits (dehisces) launching numerous black seed products.
The bulb is situated dormant after the leaves and blossom stem die back and has contractile origins that move it down further in to the soil. The bloom stem and leaves form in the light, to emerge the following season. Most species are dormant from summertime to overdue winter, flowering in the planting season, though a few kinds are fall flowering.
