Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names 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 blooms are generally white or yellow (orange or green in garden varieties), with either even or contrasting coloured tepals and corona.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten sections with around 50 species. The amount of species has assorted, depending about how they are categorised, due to similarity between hybridization and varieties. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origins of the true name Narcissus is unfamiliar, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The kinds are local to meadows and woods in southern Europe and North Africa with a centre of diversity in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were released in to the ASIA to the tenth hundred years prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.
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 overdue 19th century were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as cut blossoms and since ornamental vegetation in private and general population gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a variety of shapes and colours. Like other members of the family, narcissi produce 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 use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and skill, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as symbols of springtime. The daffodil is the countrywide blossom of Wales and the icon of cancer tumor charities in many countries. The looks of the outrageous flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an 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 regards to the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might expand as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light. The place stem usually bears a solitary bloom, but occasionally a cluster of blooms (umbel). The plants, that are usually conspicuous and white or yellowish, both or seldom renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The bouquets may hang up down (pendent), or be erect. There are 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 dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb lays dormant after the leaves and flower stem die again and has contractile origins that pull it down further in to the soil. The bloom leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from summer to overdue winter, flowering in the springtime, though a few types are autumn flowering.
