Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common titles including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The plants are usually white or yellow (orange or red in garden kinds), with either standard or contrasting colored tepals and corona.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Kinds Plantarum (1753). The genus is generally thought to have about ten parts with roughly 50 species. The true amount of types has assorted, depending how they are grouped, credited to similarity between types and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the real name Narcissus is anonymous, but it is often linked to a Greek term for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own representation. The English term 'daffodil' is apparently produced from "asphodel", with which it was likened commonly.
The species are indigenous to meadows and woods in southern European countries and North Africa with a middle of diversity in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were launched into the Far East to the tenth hundred years prior. Narcissi have a tendency 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 some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th hundred years and by the past due 19th hundred years were an important commercial crop centred mainly on the Netherlands. Narcissi are popular as lower blossoms so that as ornamental plant life in private and public gardens today. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members of these family, narcissi create a 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 use within traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in artwork and literature, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as symbols of spring and coil. The daffodil is the national bloom of Wales and the sign of cancer tumor charities in many countries. The looks of the untamed flowers in spring and coil is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage light bulb. They regrow in the next time from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might develop as tall as 80 cm.
The vegetation are scapose, having an individual central leafless hollow rose stem (scape). Several green or blue-green, small, strap-shaped leaves happen from the bulb. The plant stem bears a solitary rose, but sometimes a cluster of blossoms (umbel). The blossoms, which can be conspicuous and white or yellowish usually, sometimes both or rarely inexperienced, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may hang 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 fruit contains a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb is situated dormant following the leaves and bloom stem die again and has contractile root base that yank it down further into the soil. The bloom stem and leaves form in the light, to emerge the following season. Most species are dormant from warmer summer months to later winter, flowering in the spring and coil, though a few types are autumn flowering.
