Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common labels 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 blooms are generally white or yellowish (orange or green in garden types), with either even or contrasting coloured tepals and corona.
Narcissus were popular in traditional civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Types Plantarum (1753). The genus is generally considered to have about ten parts with roughly 50 species. The number of types has assorted, depending how they are categorized, anticipated 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 areas of southwest Europe. The exact source of the name Narcissus is undiscovered, but it is often linked to a Greek word for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own reflection. The English term 'daffodil' appears to be derived from "asphodel", with which it was commonly likened.
The kinds are native 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 released in to the Far East to the tenth century 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 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 ever more popular in Europe following the 16th century and by the overdue 19th hundred years were an important commercial crop centred primarily on holland. Narcissi are popular as trim blooms so when ornamental vegetation in private and public gardens today. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are grouped into divisions, covering an array of colours and shapes. Like other members with their family, narcissi produce 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 in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art work, narcissi are associated with a true number of themes in different cultures, ranging from death to fortune, and as icons of springtime. The daffodil is the national rose of Wales and the symbol of tumors charities in many countries. The appearance of the outrageous flowers in planting season is associated with festivals in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back after flowering for an underground storage light. They regrow in the following time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may grow as extra tall as 80 cm.
The crops are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, small, strap-shaped leaves occur from the light. The plant stem usually bears a solitary bloom, but once in a while a cluster of blossoms (umbel). The flowers, that happen to be conspicuous and white or yellow usually, sometimes both or rarely green, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical designed 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) comprising three chambers (trilocular). The fruit involves a dried capsule that splits (dehisces) launching numerous black seeds.
The bulb is placed dormant after the leaves and rose stem die again and has contractile origins that take it down further in to the soil. The bloom leaves and stem form in the light, to emerge the next season. Most types are dormant from summer to late winter, flowering in the spring, though a few kinds are fall months flowering.
