Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 the cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or red in garden varieties), with either uniform or contrasting colored corona and tepals.
Narcissus were well known in historical civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten sections with about 50 species. The true quantity of types has mixed, depending on how they are classified, anticipated to similarity between kinds and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the real name Narcissus is unknown, but it is linked to a Greek expression for intoxicated (narcotic) and the misconception of the junior of this name who fell in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The types are indigenous to meadows and woods in southern Europe 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 released into the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th hundred years and by the later 19th century were an important commercial crop centred generally on holland. Today narcissi are popular as slash blossoms as ornamental vegetation in private and general population 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 variety of shapes and colours. Like other members of these family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a true number of themes in various cultures, ranging from fatality to fortune, and as symbols of springtime. The daffodil is the nationwide flower of Wales and the icon of malignancy charities in many countries. The appearance of the untamed 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 the underground storage light bulb. They regrow in the next 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as tall 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 happen from the bulb. The plant stem bears a solitary rose, but once in a while a cluster of flowers (umbel). The blossoms, that happen to be usually conspicuous and white or yellowish, both or rarely inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The bouquets may hang up down (pendent), or be erect. There are six pollen bearing stamens adjoining a central style. The ovary is second-rate (below the floral parts) consisting of three chambers (trilocular). The berry contains a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb is situated dormant after the leaves and flower stem die again and has contractile roots that move it down further in to the soil. The rose stem and leaves form in the bulb, to emerge the following season. Most species are dormant from summertime to overdue winter, flowering in the springtime, though a few kinds are fall months flowering.
