Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names 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 way of a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or green in garden varieties), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten portions with approximately 50 species. The true volume of species has assorted, depending how they are categorised, due 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 origins of the real name Narcissus is unknown, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The species are local to meadows and woods in southern Europe and North Africa with a centre of variety in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released into the Far East 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, nematodes and mites. Some Narcissus species have become 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 overdue 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as cut bouquets so that as ornamental crops in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. Like other members of these 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 in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as symbols of spring. The daffodil is the national blossom of Wales and the icon of cancer charities in many countries. The appearance of the wild flowers in spring is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage light bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several blue-green or green, small, strap-shaped leaves come up from the bulb. The vegetable stem bears a solitary bloom, but sometimes a cluster of blossoms (umbel). The blooms, that are usually conspicuous and white or yellow, 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 exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The flowers may suspend down (pendent), or be erect. You can find six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The berry consists of a dried out capsule that splits (dehisces) releasing numerous black seed products.
The bulb lies dormant following the leaves and bloom stem die back again and has contractile origins that pull it down further in to the soil. The blossom leaves and stem form in the bulb, to emerge the next season. Most kinds are dormant from summer to later winter, flowering in the spring, though a few kinds are autumn flowering.
