Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life 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 plants are usually white or yellow (orange or green in garden types), with either standard or contrasting colored tepals and corona.
Narcissus were popular in traditional civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten areas with around 50 species. The amount of kinds has assorted, depending on how they are categorised, as a consequence to similarity between hybridization and types. The genus arose some right 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 anonymous, but it is often linked to a Greek word for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own reflection. The English phrase 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The types are indigenous to meadows and woods in southern Europe and North Africa with a middle of diversity in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before the tenth century. 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, mites and nematodes. Some Narcissus species have become extinct, while some 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 past due 19th century were an important commercial crop centred mostly on holland. Today narcissi are popular as trim blossoms as ornamental vegetation in private and open public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of shapes and colours. Like other members of their family, narcissi produce 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 use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as symbols of spring. The daffodil is the countrywide flower of Wales and the image of cancer charities in many countries. The looks of the untamed 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 yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light bulb. The place stem bears a solitary rose, but once in a while a cluster of plants (umbel). The blooms, which can be usually conspicuous and white or yellowish, sometimes both or seldom green, contain 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 disk to conical designed corona. The flowers may hang down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruits includes a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is placed dormant after the leaves and blossom stem die back again and has contractile origins that take it down further into the soil. The blossom leaves and stem form in the light, to emerge the next season. Most species are dormant from summer time to overdue winter, flowering in the planting season, though a few types are autumn flowering.
