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 used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or green in garden kinds), with either standard or contrasting colored tepals and corona.
Narcissus were well known in historical civilisation, both medicinally and botanically, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is generally thought to have about ten parts with roughly 50 species. The true amount of types has mixed, depending how they are classified, a consequence of to similarity between hybridization and kinds. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the name Narcissus is anonymous, but it is often associated with a Greek phrase for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The species are local to meadows and woods in southern European countries and North Africa with a middle of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were created in to the ASIA 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, mites and nematodes. 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 past due 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as chop bouquets and since ornamental vegetation in private and public gardens today. The long history of breeding has led to thousands 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 ingested accidentally. 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 literature and fine art, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of planting season. The daffodil is the countrywide flower of Wales and the image 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 for an underground storage light bulb. They regrow in the following season from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the light. The plant stem bears a solitary bloom, but once in a while a cluster of blooms (umbel). The blossoms, which are usually conspicuous and white or yellow, sometimes both or almost never renewable, 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 shaped corona. The flowers may suspend down (pendent), or be erect. A couple of six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits includes a dried out capsule that splits (dehisces) releasing numerous black seeds.
The bulb sits dormant after the leaves and rose stem die back again and has contractile origins that pull it down further into the soil. The flower stem and leaves form in the bulb, to emerge the next season. Most species are dormant from summer months to late winter, flowering in the planting season, though a few species are autumn flowering.
