Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life 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 blossoms are generally white or yellow (orange or green in garden varieties), with either uniform or contrasting coloured tepals and corona.
Narcissus were popular in early civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Varieties Plantarum (1753). The genus is normally considered to have about ten areas with approximately 50 species. The true amount of kinds has assorted, depending how they are labeled, a consequence of to similarity between hybridization and varieties. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origins of the true name Narcissus is unfamiliar, but it is linked to a Greek phrase for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own representation. The English expression 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The types are local to meadows and woods in southern Europe and North Africa with a center of diversity in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were presented 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, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th century and by the later 19th century were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as lower blossoms and since ornamental plants in private and public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members of the family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal utilization in traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in several cultures, ranging from fatality to fortune, and as symbols of planting season. The daffodil is the nationwide rose of Wales and the mark of tumors charities in many countries. The looks of the untamed flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to an underground storage light bulb. They regrow in the next year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may increase as large as 80 cm.
The plant life are scapose, having an individual central leafless hollow blossom stem (scape). Several green or blue-green, slim, strap-shaped leaves come up from the light. The plant stem bears a solitary blossom, but sometimes a cluster of plants (umbel). The bouquets, which are usually conspicuous and white or yellowish, sometimes both or almost never renewable, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The flowers may hang up down (pendent), or be erect. You can find six pollen bearing stamens encompassing a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The berries consists of a dry capsule that splits (dehisces) liberating numerous black seed products.
The bulb lays dormant following the leaves and blossom stem die again and has contractile origins that yank it down further into the soil. The bloom leaves and stem form in the light, to emerge the following season. Most species are dormant from warmer summer months to past due winter, flowering in the spring and coil, though a few kinds are autumn flowering.
