Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common brands 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 way of a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or pink in garden varieties), with either even or contrasting coloured corona and tepals.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is normally considered to have about ten parts with roughly 50 species. The true range of varieties has assorted, depending on how they are categorized, anticipated to similarity between varieties and hybridization. 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 origins of the name Narcissus is mysterious, but it is linked to a Greek expression for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own reflection. The English word 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The species are native to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were presented into the ASIA to the tenth century 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, 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 past due 19th hundred years were an important commercial crop centred generally on the Netherlands. Narcissi are popular as slash blossoms so that ornamental vegetation in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi produce a 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 used in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in several cultures, ranging from loss of life to fortune, and as icons of springtime. The daffodil is the nationwide blossom of Wales and the icon 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 back after flowering to an underground storage bulb. They regrow in the next calendar year from brown-skinned ovoid lights with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might increase as extra tall as 80 cm.
The plants are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves come up from the light bulb. The plant stem usually bears a solitary rose, but occasionally a cluster of plants (umbel). The blossoms, that happen to be conspicuous and white or yellowish usually, sometimes both or almost never green, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blooms may hang up down (pendent), or be erect. You will find six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berry consists of a dry capsule that splits (dehisces) releasing numerous black seeds.
The bulb is dormant following the leaves and flower stem die back again and has contractile origins that yank it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most varieties are dormant from summer season to overdue winter, flowering in the springtime, though a few species are autumn flowering.
