Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common names 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 by a cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or red in garden kinds), with either even or contrasting coloured corona and tepals.
Narcissus were well known in ancient civilisation, both and botanically medicinally, but formally detailed by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten portions with about 50 species. The amount of kinds has varied, depending about how they are classified, due to similarity between hybridization and species. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The exact source of the true name Narcissus is anonymous, but it is often associated with a Greek word for intoxicated (narcotic) and the misconception of the children of that name who fell in love with his own representation. The English term 'daffodil' appears to be derived from "asphodel", with which it was likened commonly.
The kinds are local to meadows and woods in southern Europe and North Africa with a middle of diversity in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were released into the ASIA to the tenth century prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. 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 tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe following the 16th century and by the later 19th hundred years were an important commercial crop centred generally on holland. Narcissi are popular as slash plants as ornamental crops in private and public gardens today. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering a wide range of colours and shapes. Like other members of the family, narcissi produce a number of different alkaloids, which provide some protection for the plant, but may be poisonous if accidentally ingested. 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 skill and literature, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as symbols of planting season. The daffodil is the national bloom of Wales and the image of cancers charities in many countries. The appearance 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 for an underground storage light bulb. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may develop as large as 80 cm.
The crops are scapose, having a single central leafless hollow flower stem (scape). Several blue-green or green, thin, strap-shaped leaves arise from the light bulb. The place stem usually bears a solitary blossom, but occasionally a cluster of blossoms (umbel). The blossoms, which can be conspicuous and white or yellowish usually, sometimes both or seldom inexperienced, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outside ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The bouquets may hang down (pendent), or be erect. You can find six pollen bearing stamens surrounding a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The fruit contains a dry capsule that splits (dehisces) liberating numerous black seeds.
The bulb is situated dormant following the leaves and rose stem die back again and has contractile root base that take it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the following season. Most species are dormant from summer season to later winter, flowering in the spring and coil, though a few kinds are autumn flowering.
