Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants 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 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 usually white or yellow (orange or pink in garden types), with either standard or contrasting colored tepals and corona.
Narcissus were popular in ancient civilisation, both and botanically medicinally, but formally described by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten portions with about 50 species. The number of types has varied, depending about how they are categorized, due to similarity between hybridization and kinds. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the real name Narcissus is undiscovered, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own reflection. The English expression 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.
The species are indigenous 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 introduced in to the Far East prior to 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 earliest times, but became increasingly popular in Europe after the 16th century and by the late 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as trim bouquets so when ornamental crops in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of colours and shapes. Like other members of these 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 utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and artwork, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as icons of spring and coil. The daffodil is the nationwide blossom of Wales and the icon of cancer tumor charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light. They regrow in the next yr from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as large as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves occur from the light. The flower stem bears a solitary blossom, but once in a while a cluster of flowers (umbel). The blooms, which are conspicuous and white or yellow usually, sometimes both or hardly ever inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical formed corona. The blooms may suspend down (pendent), or be erect. There are six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berry consists of a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant following the leaves and bloom stem die back and has contractile origins that move it down further into the soil. The bloom stem and leaves form in the light, to emerge the following season. Most varieties are dormant from warmer summer months to later winter, flowering in the springtime, though a few varieties are autumn flowering.
