Narcissus Avalanche

Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common names 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 a cup- or trumpet-shaped corona. The blossoms are usually white or yellowish (orange or green in garden types), with either standard or contrasting coloured tepals and corona.

Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is generally thought to have about ten parts with roughly 50 species. The amount of varieties has assorted, depending on how they are labeled, as a consequence to similarity between hybridization and kinds. 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 source of the name Narcissus is unknown, but it is associated with a Greek word for intoxicated (narcotic) and the misconception of the youngsters of that name who fell in love with his own representation. The English expression 'daffodil' is apparently derived from "asphodel", with which it was compared commonly.

The species are indigenous to meadows and woods in southern Europe and North Africa with a center of variety in the Western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were released in to the ASIA to the tenth century prior. Narcissi have a tendency 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, 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 following the 16th hundred years and by the late 19th century were an important commercial crop centred mainly on holland. Narcissi are popular as chop blossoms and as ornamental plants in private and open public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering an array of shapes and colours. Like other members with their 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 use in traditional healing and has led to the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in literature and art, narcissi are associated with a number of themes in various cultures, ranging from loss of life to fortune, and as icons of springtime. The daffodil is the national rose of Wales and the icon of cancer tumor charities in many countries. The looks of the outdoors flowers in spring is associated with festivals in many places.

Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage light bulb. They regrow in the next time 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 level of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.

The crops are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, slim, strap-shaped leaves occur from the bulb. The herb stem usually bears a solitary rose, but sometimes a cluster of bouquets (umbel). The blossoms, that are usually conspicuous and white or yellowish, sometimes both or almost never renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The flowers 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 super fruit contains a dried out capsule that splits (dehisces) liberating numerous black seed products.

The bulb lays dormant after the leaves and bloom stem die again and has contractile origins that yank it down further in to the soil. The blossom stem and leaves form in the light bulb, to emerge the following season. Most kinds are dormant from summer months to past due winter, flowering in the spring, though a few varieties are fall months flowering.
