Narcissistic personality disorder

Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being 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 blossoms are generally white or yellow (orange or pink in garden kinds), with either standard or contrasting colored tepals and corona.

Narcissus were popular in historic civilisation, both medicinally and botanically, but formally detailed by Linnaeus in his Kinds Plantarum (1753). The genus is generally considered to have about ten areas with roughly 50 species. The true number of varieties has mixed, depending about how they are classified, anticipated to similarity between types and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the name Narcissus is mysterious, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own reflection. The English word 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.

The species are native to meadows and woods in southern European countries and North Africa with a middle of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were introduced into the Far East before the tenth century. 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 some are threatened by increasing tourism and urbanisation.

Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as chop flowers as ornamental vegetation in private and open public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of shapes and colours. Like other members of these 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 resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and books, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as icons of spring. The daffodil is the national rose of Wales and the symbol of tumor charities in many countries. The appearance of the untamed flowers in spring is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage bulb. They regrow in the following yr from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might develop as extra tall as 80 cm.

The vegetation are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, thin, strap-shaped leaves happen from the light. The vegetable stem bears a solitary bloom, but sometimes a cluster of blooms (umbel). The bouquets, that are usually conspicuous and white or yellow, sometimes both or rarely green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The bouquets may hang up down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berry contains a dried up capsule that splits (dehisces) releasing numerous black seeds.

The bulb lies dormant after the leaves and bloom stem die again and has contractile origins that yank it down further in to the soil. The blossom leaves and stem form in the light, to emerge the next season. Most species are dormant from warmer summer months to late winter, flowering in the spring and coil, though a few species are fall months flowering.
