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 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 usually white or yellow (orange or green in garden kinds), with either even or contrasting colored tepals and corona.
Narcissus were well known in traditional civilisation, both and botanically medicinally, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is normally thought to have about ten parts with around 50 species. The true range of varieties has varied, depending how they are categorised, credited to similarity between varieties and hybridization. The genus arose time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas 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 youngsters of this name who fell deeply in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The types are native to meadows and woods in southern Europe and North Africa with a middle of variety in the Western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the ASIA to the tenth hundred years prior. Narcissi have a tendency 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 others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became ever more popular in Europe after the 16th century and by the past due 19th century were an important commercial crop centred primarily on holland. Today narcissi are popular as chop bouquets and as ornamental crops in private and general public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array 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 ingested accidentally. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in skill and literature, narcissi are associated with a number of themes in various cultures, ranging from death to fortune, and as symbols of spring and coil. The daffodil is the nationwide blossom of Wales and the sign of cancers charities in many countries. The appearance of the untamed flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering to a underground storage light bulb. They regrow in the next season from brown-skinned ovoid bulbs with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf varieties such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as high 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 arise from the light bulb. The plant stem bears a solitary blossom, but once in a while a cluster of blooms (umbel). The bouquets, that happen to be conspicuous and white or yellowish usually, sometimes both or rarely renewable, consist of 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 designed corona. The blooms may suspend down (pendent), or be erect. A couple of six pollen bearing stamens encompassing a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The super fruit includes a dried up capsule that splits (dehisces) releasing numerous black seeds.
The bulb sits dormant following the leaves and blossom stem die back and has contractile origins that take it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the next season. Most species are dormant from summer season to later winter, flowering in the spring, though a few species are fall months flowering.
