Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial vegetation in the Amaryllidaceae (amaryllis) family. Various common labels 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 plants are usually white or yellowish (orange or green in garden types), with either even or contrasting coloured corona and tepals.
Narcissus were well known in historic civilisation, both and botanically medicinally, but formally described by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten portions with roughly 50 species. The true quantity of varieties has assorted, depending on how they are categorized, a consequence of 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 origin of the name Narcissus is undiscovered, but it is associated with a Greek term for intoxicated (narcotic) and the misconception of the children of this name who fell deeply in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly compared.
The kinds are local to meadows and woods in southern Europe and North Africa with a middle of variety in the Traditional western Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced 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, nematodes and mites. Some Narcissus species have grown to be extinct, while others are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe after the 16th century and by the overdue 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slice flowers so when ornamental plant life 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 labeled into divisions, covering a variety of shapes and colours. Like other members of their 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 use within traditional healing and has resulted in 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 different cultures, ranging from fatality to good fortune, and as symbols of spring. The daffodil is the nationwide rose of Wales and the mark of cancers charities in many countries. The looks of the crazy flowers in spring and coil is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to a underground storage bulb. They regrow in the following year from brown-skinned ovoid bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf types such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may expand as large as 80 cm.
The plant life are scapose, having a single central leafless hollow bloom stem (scape). Several blue-green or green, small, strap-shaped leaves occur from the light bulb. The seed stem bears a solitary rose, but occasionally a cluster of blossoms (umbel). The blossoms, that are conspicuous and white or yellow usually, both or rarely inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an outside ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical shaped corona. The blooms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens adjoining a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The berries involves a dry capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant following the leaves and flower stem die back and has contractile origins that pull it down further in to the soil. The bloom stem and leaves form in the light bulb, to emerge the next season. Most kinds are dormant from warmer summer months to late winter, flowering in the planting season, though a few varieties are autumn flowering.
