Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels 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 a cup- or trumpet-shaped corona. The blossoms are usually white or yellow (orange or green in garden types), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in historical civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is normally considered to have about ten sections with approximately 50 species. The amount of species has mixed, depending on how they are categorized, a consequence of to similarity between hybridization and species. 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 origin of the name Narcissus is unfamiliar, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the youth of that name who fell deeply in love with his own reflection. The English expression 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern European countries and North Africa with a middle of variety in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the Far East before the tenth century. 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 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 ever more popular in Europe after the 16th hundred years and by the late 19th hundred years were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as slice blossoms as ornamental plant life in private and public gardens. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of colours and shapes. 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 resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and artwork, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as symbols of spring and coil. The daffodil is the countrywide blossom of Wales and the icon of malignancy charities in many countries. The appearance of the untamed flowers in springtime is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering with an underground storage light bulb. They regrow in the following yr from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf kinds such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might expand as large as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, small, strap-shaped leaves come up from the light bulb. The flower stem usually bears a solitary blossom, but sometimes a cluster of blooms (umbel). The blossoms, that happen to be conspicuous and white or yellowish usually, sometimes both or rarely inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed corona. The flowers may hang down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit involves a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb is placed dormant following the leaves and flower stem die back and has contractile origins that take it down further into the soil. The flower stem and leaves form in the light, to emerge the next season. Most species are dormant from summer months to overdue winter, flowering in the spring, though a few types are autumn flowering.
