Narcissus /n?:r's?s?s/ is a genus of predominantly 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 by a cup- or trumpet-shaped corona. The blooms are generally white or yellow (orange or red in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were well known in early civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten sections with roughly 50 species. The number of types has varied, depending about how they are categorised, scheduled to similarity between kinds 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 exact origins of the true name Narcissus is unidentified, but it is often associated with a Greek expression for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was commonly likened.
The varieties are local to meadows and woods in southern Europe and North Africa with a centre of diversity in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced in to the ASIA to the tenth hundred years prior. Narcissi tend 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 urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the past due 19th century were an important commercial crop centred mostly on the Netherlands. Narcissi are popular as cut bouquets so that as ornamental plant life in private and general population gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled 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 ingested inadvertently. 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 artwork and books, narcissi are associated with a number of themes in several cultures, ranging from fatality to good fortune, and as symbols of spring. The daffodil is the countrywide bloom of Wales and the mark of tumors charities in many countries. The appearance of the crazy flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage bulb. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach levels 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 might increase as tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the bulb. The flower stem bears a solitary rose, but once in a while a cluster of plants (umbel). The blooms, which can be usually conspicuous and white or yellowish, sometimes both or rarely green, 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 disk to conical formed corona. The flowers may suspend down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The super fruit consists of a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb lays dormant after the leaves and flower stem die again and has contractile origins that yank it down further in to the soil. The rose stem and leaves form in the light, to emerge the next season. Most types are dormant from warmer summer months to later winter, flowering in the spring and coil, though a few species are autumn flowering.
