Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands 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 a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or green in garden varieties), with either standard or contrasting colored corona and tepals.
Narcissus were well known in old civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten areas with roughly 50 species. The amount of species has varied, depending how they are categorized, thanks to similarity between hybridization and kinds. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the real name Narcissus is undiscovered, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the youngsters of this name who fell in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The types are native to meadows and woods in southern European countries 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 introduced in to the Far East before the tenth century. Narcissi have a tendency 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 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. Today narcissi are popular as slash bouquets so when ornamental crops in private and general public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of shapes and colours. 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 skill, narcissi are associated with a true number of themes in various cultures, ranging from death to good fortune, and as icons of spring and coil. The daffodil is the nationwide flower of Wales and the icon of tumor charities in many countries. The looks of the wild flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light. They regrow in the next yr from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the light bulb. The plant stem usually bears a solitary rose, but once in a while a cluster of blossoms (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, both or rarely renewable sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang up down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berry consists of a dried out capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and rose stem die again and has contractile roots that move it down further in to the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from warmer summer months to overdue winter, flowering in the spring and coil, though a few types are fall months flowering.
