Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 with a cup- or trumpet-shaped corona. The flowers are usually white or yellow (orange or red in garden types), with either even or contrasting colored corona and tepals.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten sections with about 50 species. The amount of varieties has mixed, depending about how they are classified, thanks to similarity between hybridization and varieties. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise origins of the name Narcissus is unknown, but it is often linked to a Greek term for intoxicated (narcotic) and the misconception of the youth of this name who fell deeply in love with his own representation. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The types are indigenous to meadows and woods in southern Europe and North Africa with a centre of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were unveiled 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, 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 earliest times, but became ever more popular in Europe following the 16th century and by the past due 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as cut plants and as ornamental vegetation in private and open public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering an array of shapes and colours. Like other members of these 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 use within traditional healing and has led to 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 different cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the countrywide rose of Wales and the image of tumor charities in many countries. The appearance of the untamed flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to an underground storage light bulb. They regrow in the next time from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves arise from the light bulb. The vegetable stem bears a solitary flower, but sometimes a cluster of bouquets (umbel). The flowers, that are conspicuous and white or yellowish usually, both or rarely green sometimes, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The blooms may suspend down (pendent), or be erect. You will find six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruits involves a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb lays dormant after the leaves and rose stem die back and has contractile root base that yank it down further into the soil. The flower leaves and stem form in the light, to emerge the following season. Most types are dormant from summer time to later winter, flowering in the spring and coil, though a few varieties are fall flowering.
