Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or pink in garden kinds), with either even or contrasting colored corona and tepals.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten areas with roughly 50 species. The number of kinds has mixed, depending about how they are classified, a consequence of to similarity between hybridization and varieties. The genus arose some 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 unknown, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The types are local to meadows and woods in southern European countries and North Africa with a centre of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released into the Far East to the tenth hundred years prior. 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 initial times, but became increasingly popular in Europe after the 16th century and by the past due 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as trim blossoms and since ornamental plants in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array 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 ingested unintentionally. This property has been exploited for medicinal use in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a true number of themes in various cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the countrywide rose of Wales and the icon of cancer tumor charities in many countries. The looks of the outrageous flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage bulb. They regrow in the following calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may increase as tall as 80 cm.
The plant life are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the bulb. The herb stem bears a solitary blossom, but occasionally a cluster of bouquets (umbel). The blooms, which can be usually conspicuous and white or yellowish, sometimes both or rarely renewable, consist of 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 disc to conical molded corona. The plants may suspend 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 berry involves a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb lies dormant after the leaves and rose stem die again and has contractile root base that move it down further into the soil. The flower leaves and stem form in the bulb, to emerge the next season. Most species are dormant from summer to overdue winter, flowering in the spring and coil, though a few species are autumn flowering.
