Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or red in garden varieties), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten sections with roughly 50 species. The true volume of kinds has mixed, depending how they are grouped, due to similarity between hybridization and varieties. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the true name Narcissus is unfamiliar, but it is associated with a Greek phrase for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own representation. The English term 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The kinds are local to meadows and woods in southern European countries and North Africa with a center of diversity in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were launched in to the ASIA to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th hundred years and by the past due 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as chop blossoms so that ornamental plant life in private and general public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of colours and shapes. Like other members of their 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 used in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a true number of themes in different cultures, ranging from fatality to fortune, and as icons of spring and coil. The daffodil is the countrywide rose of Wales and the sign of cancer tumor charities in many countries. The looks 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 with an underground storage light bulb. They regrow in the next year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The plants are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves occur from the light. The plant stem bears a solitary rose, but sometimes a cluster of bouquets (umbel). The blossoms, which are usually conspicuous and white or yellowish, both or hardly ever green sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The bouquets may suspend down (pendent), or be erect. A couple of six pollen bearing stamens adjoining a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The super fruit includes a dry out capsule that splits (dehisces) launching numerous black seed products.
The bulb is situated dormant after the leaves and bloom stem die again and has contractile root base that take it down further into the soil. The bloom leaves and stem form in the light, to emerge the next season. Most species are dormant from summer season to late winter, flowering in the spring and coil, though a few species are fall months flowering.
