Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names 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 way of a cup- or trumpet-shaped corona. The bouquets are usually white or yellowish (orange or pink in garden types), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is generally considered to have about ten parts with approximately 50 species. The true variety of varieties has assorted, depending on how they are labeled, as a consequence to similarity between hybridization and kinds. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the name Narcissus is unfamiliar, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the junior of that name who fell deeply in love with his own representation. The English term 'daffodil' appears to be produced from "asphodel", with which it was compared commonly.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a middle of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were created in to the ASIA to the tenth century 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, nematodes and mites. 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 hundred years and by the overdue 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as trim blooms and since ornamental plant life in private and public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a wide range of colours and shapes. Like other members with their family, narcissi create 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 within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art and books, narcissi are associated with a true number of themes in different cultures, ranging from death to fortune, and as symbols of planting season. The daffodil is the national rose of Wales and the sign of malignancy 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 again after flowering for an underground storage bulb. They regrow in the following year from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The vegetation are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves arise from the bulb. The flower stem usually bears a solitary flower, but sometimes a cluster of flowers (umbel). The flowers, that are usually conspicuous and white or yellowish, sometimes both or hardly ever renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The plants may hang up down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant following the leaves and flower stem die again and has contractile root base that pull it down further into the soil. The bloom leaves and stem form in the light bulb, to emerge the following season. Most types are dormant from warmer summer months to past due winter, flowering in the spring, though a few species are fall flowering.
