Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels 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 with a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or red in garden varieties), with either uniform or contrasting colored tepals and corona.
Narcissus were well known in early civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten areas with about 50 species. The number of kinds has varied, depending how they are labeled, thanks to similarity between hybridization and types. 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 precise source of the name Narcissus is unidentified, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the children of this name who fell in love with his own reflection. The English term 'daffodil' is apparently derived from "asphodel", with which it was likened commonly.
The types are local to meadows and woods in southern Europe and North Africa with a center of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were launched into the Far East to the tenth century prior. Narcissi tend 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 others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe following the 16th century and by the late 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as lower blooms so that ornamental crops in private and general population gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of colours and shapes. Like other members of the family, narcissi create a true 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 used in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a true number of themes in different cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the countrywide flower of Wales and the symbol of cancer charities in many countries. The appearance of the outdoors 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 yr from brown-skinned ovoid lights 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 vegetation are scapose, having a single central leafless hollow rose stem (scape). Several green or blue-green, narrow, strap-shaped leaves occur from the light bulb. The plant stem bears a solitary rose, but sometimes a cluster of plants (umbel). The flowers, which are conspicuous and white or yellow usually, sometimes both or rarely green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blossoms may hang down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruits involves a dried capsule that splits (dehisces) liberating numerous black seed products.
The bulb lays dormant after the leaves and rose stem die again and has contractile origins that move it down further in to the soil. The bloom stem and leaves form in the light, to emerge the next season. Most kinds are dormant from warmer summer months to overdue winter, flowering in the springtime, though a few kinds are fall flowering.
