Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation 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 members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The blooms are usually white or yellowish (orange or pink in garden types), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally described by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten parts with around 50 species. The amount of species has mixed, depending on how they are categorised, scheduled to similarity between species and hybridization. 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 origins of the name Narcissus is unfamiliar, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the young ones of that name who fell in love with his own representation. The English expression 'daffodil' appears to be produced from "asphodel", with which it was commonly compared.
The types are local to meadows and woods in southern European countries and North Africa with a middle of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were introduced into the ASIA to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are also insect-pollinated. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. 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 past due 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slice flowers and since ornamental vegetation in private and general public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering a variety of shapes and colours. Like other members of these family, narcissi produce a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested unintentionally. 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 art and literature, narcissi are associated with a number of themes in different cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the national rose of Wales and the icon of cancer charities in many countries. The looks of the wild flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to an underground storage light bulb. They regrow in the following season from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as tall as 80 cm.
The vegetation are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, narrow, strap-shaped leaves happen from the light. The flower stem bears a solitary rose, but once in a while a cluster of plants (umbel). The flowers, which can be conspicuous and white or yellowish usually, sometimes both or seldom green, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blooms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries involves a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb lies dormant following the leaves and blossom stem die again and has contractile root base that take it down further in to the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most species are dormant from summer months to later winter, flowering in the spring, though a few kinds are fall months flowering.
