Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial plants 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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or red in garden types), with either even or contrasting coloured tepals and corona.
Narcissus were popular in historic civilisation, both and botanically medicinally, but formally referred to by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten sections with roughly 50 species. The true quantity of varieties has varied, depending on how they are classified, credited to similarity between types and hybridization. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact source of the name Narcissus is undiscovered, but it is linked to a Greek term for intoxicated (narcotic) and the myth of the junior of this name who fell in love with his own representation. The English phrase 'daffodil' appears to be produced from "asphodel", with which it was likened commonly.
The varieties are local to meadows and woods in southern European countries and North Africa with a center of diversity in the American Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were introduced in to the Far East prior to the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th hundred years and by the later 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as chop bouquets and since ornamental crops in private and open public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering a wide range 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 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 fine art, narcissi are associated with a true number of themes in various cultures, ranging from fatality to good fortune, and as symbols of planting season. The daffodil is the nationwide bloom of Wales and the sign of tumor charities in many countries. The appearance of the outdoors flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage bulb. They regrow in the following calendar year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with respect to the species. Dwarf kinds such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might grow as large as 80 cm.
The crops are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the bulb. The place stem bears a solitary rose, but sometimes a cluster of bouquets (umbel). The blossoms, which are conspicuous and white or yellow usually, both or rarely renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blossoms may hang up down (pendent), or be erect. There are six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The super fruit consists of a dried capsule that splits (dehisces) launching numerous black seed products.
The bulb lies dormant following the leaves and blossom stem die again and has contractile roots that yank it down further into the soil. The flower leaves and stem form in the light bulb, to emerge the next season. Most types are dormant from warmer summer months to past due winter, flowering in the springtime, though a few kinds are autumn flowering.
