Narcissus /n?:r's?s?s/ is a genus of mainly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands 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 blossoms are generally white or yellow (orange or pink in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were popular in early civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Species Plantarum (1753). The genus is normally thought to have about ten portions with about 50 species. The true amount of varieties has mixed, depending about how they are categorized, due to similarity between hybridization and kinds. The genus arose some 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 unfamiliar, but it is linked to a Greek expression for intoxicated (narcotic) and the misconception of the youngsters of that name who fell deeply in love with his own reflection. The English expression 'daffodil' appears to be derived from "asphodel", with which it was commonly compared.
The types are local to meadows and woods in southern Europe and North Africa with a centre of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were launched 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, disorders and diseases 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 initial times, but became ever more popular in Europe following the 16th century and by the past due 19th century were an important commercial crop centred primarily on holland. Narcissi are popular as slice bouquets so that as ornamental vegetation in private and public gardens today. The long history of breeding has resulted in a large number of different cultivars. For horticultural purposes, narcissi are classified into divisions, covering a variety of colours and shapes. Like other members of the family, narcissi produce a true 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 in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art and literature, narcissi are associated with a true number of themes in several cultures, ranging from loss of life to good fortune, and as symbols of spring and coil. The daffodil is the nationwide blossom of Wales and the mark of tumor 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 again after flowering for an underground storage light bulb. They regrow in the next season from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta might grow as high as 80 cm.
The plant life are scapose, having a single central leafless hollow blossom stem (scape). Several green or blue-green, small, strap-shaped leaves come up from the light. The herb stem usually bears a solitary blossom, but occasionally a cluster of flowers (umbel). The blooms, which can be conspicuous and white or yellowish usually, sometimes both or hardly ever inexperienced, 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 disc to conical designed corona. The plants may suspend down (pendent), or be erect. You will find six pollen bearing stamens surrounding a central style. The ovary is substandard (below the floral parts) comprising three chambers (trilocular). The fruit includes a dried up capsule that splits (dehisces) releasing numerous black seed products.
The bulb sits dormant following the leaves and blossom stem die back and has contractile root base that pull it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the following season. Most types are dormant from summer months to past due winter, flowering in the spring, though a few kinds are fall months flowering.
