Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles 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 by a cup- or trumpet-shaped corona. The flowers are usually white or yellowish (orange or pink in garden varieties), with either even or contrasting colored tepals and corona.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten sections with about 50 species. The amount of species has assorted, depending about how they are grouped, anticipated to similarity between species and hybridization. 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 real name Narcissus is unknown, but it is associated with a Greek phrase for intoxicated (narcotic) and the myth of the young ones of that name who fell in love with his own reflection. The English term 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The types are native to meadows and woods in southern Europe and North Africa with a centre of variety in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild 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, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. 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 increasingly popular in Europe after the 16th century and by the past due 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as trim bouquets so that ornamental vegetation in private and general population 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 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 accidentally ingested. This property has been exploited for medicinal use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and fine art, narcissi are associated with a number of themes in several cultures, ranging from fatality to fortune, and as symbols of spring and coil. The daffodil is the national flower of Wales and the mark of cancer tumor charities in many countries. The looks of the wild flowers in spring and coil is associated with festivals 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 next season from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.
The plants are scapose, having an individual central leafless hollow flower stem (scape). Several blue-green or green, slim, strap-shaped leaves occur from the light. The herb stem bears a solitary bloom, but occasionally a cluster of blossoms (umbel). The flowers, which can be conspicuous and white or yellow usually, sometimes both or hardly ever inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blossoms may hang up down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berry involves a dry capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and flower stem die back and has contractile origins that move it down further in to the soil. The bloom stem and leaves form in the light, to emerge the following season. Most kinds are dormant from warmer summer months to past due winter, flowering in the spring and coil, though a few kinds are autumn flowering.
