Narcissus /n?:r's?s?s/ is a genus of mainly 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 with a cup- or trumpet-shaped corona. The blossoms are generally white or yellowish (orange or red in garden varieties), with either uniform or contrasting colored corona and tepals.
Narcissus were popular in early civilisation, both and botanically medicinally, but formally described by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten parts with roughly 50 species. The true range of kinds has assorted, depending about how they are classified, credited to similarity between types and hybridization. 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 exact origins of the real name Narcissus is anonymous, but it is associated with a Greek expression for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own representation. The English phrase 'daffodil' appears to be 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 center of diversity in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were presented into the ASIA 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, diseases and disorders 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 earliest times, but became increasingly popular in Europe following the 16th hundred years and by the overdue 19th century were an important commercial crop centred mostly on holland. Today narcissi are popular as cut plants as ornamental plants in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi create 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 within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as icons of planting season. The daffodil is the nationwide flower of Wales and the sign of malignancy charities in many countries. The appearance of the wild flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage bulb. They regrow in the next season from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may develop as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, slim, strap-shaped leaves occur from the light. The herb stem bears a solitary bloom, but sometimes a cluster of bouquets (umbel). The bouquets, that are usually conspicuous and white or yellowish, both or almost never inexperienced sometimes, 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 disk to conical formed corona. The flowers may hang down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry involves a dry capsule that splits (dehisces) releasing numerous black seed products.
The bulb is dormant following the leaves and blossom stem die again and has contractile roots that pull it down further into the soil. The rose leaves and stem form in the bulb, to emerge the next season. Most types are dormant from summertime to later winter, flowering in the planting season, though a few types are autumn flowering.
