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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or red in garden varieties), with either even or contrasting coloured tepals and corona.
Narcissus were popular 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 portions with roughly 50 species. The true quantity of varieties has mixed, depending how they are categorized, as a consequence to similarity between hybridization and types. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact origin of the real name Narcissus is mysterious, but it is often linked to a Greek expression for intoxicated (narcotic) and the myth of the junior of that name who fell deeply in love with his own representation. The English expression 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The types are indigenous to meadows and woods in southern European countries 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 presented in to 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, 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 initial times, but became ever more popular in Europe following the 16th century and by the later 19th hundred years were an important commercial crop centred mostly on holland. Narcissi are popular as slash plants and since ornamental plant life in private and open public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members of the family, narcissi produce a true 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 within traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in literature and skill, narcissi are associated with a true number of themes in various cultures, ranging from loss of life to fortune, and as icons of springtime. The daffodil is the countrywide blossom of Wales and the sign of tumor charities in many countries. The looks of the crazy flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light. They regrow in the following time from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as high as 80 cm.
The crops are scapose, having a single central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves come up from the bulb. The plant stem usually bears a solitary blossom, but occasionally a cluster of blossoms (umbel). The plants, which can be usually conspicuous and white or yellowish, sometimes both or almost never renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blossoms may suspend down (pendent), or be erect. You will find six pollen bearing stamens bordering a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dried capsule that splits (dehisces) liberating numerous black seeds.
The bulb sits dormant following the leaves and blossom stem die again and has contractile roots that pull it down further in to the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from summer season to overdue winter, flowering in the spring and coil, though a few species are fall months flowering.
