Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 plants are usually white or yellowish (orange or pink in garden types), with either standard or contrasting coloured corona and tepals.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally described by Linnaeus in his Species Plantarum (1753). The genus is generally considered to have about ten parts with roughly 50 species. The true range of species has varied, depending on how they are grouped, due 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 precise origin of the true name Narcissus is unknown, but it is often associated with a Greek term for intoxicated (narcotic) and the myth of the young ones of this name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The kinds are native to meadows and woods in southern European countries and North Africa with a center of diversity in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the ASIA to the tenth hundred years prior. Narcissi have a tendency 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, mites and nematodes. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th hundred years and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as slice bouquets as ornamental crops 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 labeled into divisions, covering a variety of shapes and colours. Like other members of their 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 artwork and books, narcissi are associated with a number of themes in several cultures, ranging from loss of life to fortune, and as symbols of springtime. The daffodil is the nationwide flower of Wales and the icon of cancers charities in many countries. The looks of the outdoors flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to the underground storage light bulb. They regrow in the next season from brown-skinned ovoid light bulbs with pronounced necks, and reach levels 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 large as 80 cm.
The plants are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, narrow, strap-shaped leaves come up from the light. The flower stem bears a solitary flower, but once in a while a cluster of blooms (umbel). The plants, which are usually conspicuous and white or yellowish, sometimes both or hardly ever green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The blooms may hang down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries involves a dry out capsule that splits (dehisces) launching numerous black seeds.
The bulb is situated dormant following the leaves and flower stem die back again and has contractile root base that pull it down further into the soil. The blossom leaves and stem form in the bulb, to emerge the following season. Most kinds are dormant from summertime to past due winter, flowering in the spring and coil, though a few varieties are fall months flowering.
