Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common labels 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 with a cup- or trumpet-shaped corona. The bouquets are generally white or yellowish (orange or red in garden varieties), with either uniform or contrasting colored tepals and corona.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten sections with approximately 50 species. The number of varieties has mixed, depending about how they are labeled, due to similarity between varieties and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is unfamiliar, but it is often linked to a Greek word for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The species are indigenous to meadows and woods in southern Europe and North Africa with a center 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, nematodes and mites. Some Narcissus species have become extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more 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. Today narcissi are popular as trim blooms and as ornamental plant life in private and public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a wide range of shapes and colours. Like other members of their family, narcissi create 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to good fortune, and as symbols of spring. The daffodil is the countrywide blossom of Wales and the icon of tumor charities in many countries. The appearance of the wild flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage light bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may increase as tall as 80 cm.
The plant life are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light bulb. The plant stem bears a solitary blossom, but occasionally a cluster of blooms (umbel). The blooms, that happen to be usually conspicuous and white or yellow, sometimes both or almost never inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang down (pendent), or be erect. You can find six pollen bearing stamens bordering a central style. The ovary is substandard (below the floral parts) consisting of three chambers (trilocular). The fruit includes a dried up capsule that splits (dehisces) liberating numerous black seeds.
The bulb is dormant after the leaves and flower stem die again and has contractile origins that move it down further into the soil. The bloom stem and leaves form in the light, to emerge the next season. Most types are dormant from summer season to overdue winter, flowering in the springtime, though a few species are autumn flowering.
