Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles 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 usually white or yellowish (orange or green in garden kinds), with either even or contrasting coloured corona and tepals.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The true number of species has mixed, depending about how they are grouped, due to similarity between hybridization and species. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the real name Narcissus is unidentified, but it is often associated with a Greek phrase for intoxicated (narcotic) and the myth of the junior of that name who fell deeply in love with his own representation. The English word 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The species are native to meadows and woods in southern Europe and North Africa with a middle of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were presented into 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, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have grown to be 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 after the 16th century and by the overdue 19th century were an important commercial crop centred mostly on holland. Narcissi are popular as slice blooms so that ornamental plants in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of colours and shapes. 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 ingested accidentally. This property has been exploited for medicinal used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a number of themes in different cultures, ranging from fatality to fortune, and as icons of spring. The daffodil is the nationwide bloom of Wales and the icon of tumor charities in many countries. The looks of the outdoors flowers in spring is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering for an underground storage light. They regrow in the next yr from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as large as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the light. The flower stem bears a solitary rose, but occasionally a cluster of plants (umbel). The plants, that are usually conspicuous and white or yellowish, both or seldom inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical shaped corona. The flowers may hang down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berries involves a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb lies dormant following the leaves and flower stem die again and has contractile origins that move it down further into the soil. The rose leaves and stem form in the light, to emerge the next season. Most kinds are dormant from summer months to later winter, flowering in the springtime, though a few kinds are fall flowering.
