Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial vegetation 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 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 generally white or yellowish (orange or green in garden types), with either uniform or contrasting coloured corona and tepals.
Narcissus were popular in old civilisation, both medicinally and botanically, but formally referred to by Linnaeus in his Species Plantarum (1753). The genus is normally considered to have about ten parts with roughly 50 species. The true amount of types has mixed, depending how they are categorized, as a consequence to similarity between hybridization and varieties. 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 precise source of the real name Narcissus is mysterious, but it is linked to a Greek word for intoxicated (narcotic) and the misconception of the junior of that name who fell in love with his own representation. The English expression 'daffodil' appears to be derived from "asphodel", with which it was compared commonly.
The kinds are indigenous to meadows and woods in southern European countries and North Africa with a center of variety in the European Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were unveiled into the ASIA to the tenth hundred years prior. Narcissi tend 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 some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became ever more popular in Europe after the 16th hundred years and by the later 19th hundred years were an important commercial crop centred generally on the Netherlands. Today narcissi are popular as cut flowers so when ornamental plant life in private and general public gardens. The long history of breeding has resulted in thousands of different cultivars. For horticultural purposes, narcissi are categorised into divisions, covering a variety of shapes and colours. Like other members with their family, narcissi create 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 treatment of Alzheimer's dementia. Long celebrated in skill and books, narcissi are associated with a true number of themes in different cultures, ranging from loss of life to fortune, and as icons of spring. The daffodil is the nationwide bloom of Wales and the sign of cancers charities in many countries. The looks of the outrageous flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering to a underground storage light. They regrow in the following calendar year from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm depending on the species. Dwarf kinds such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta might increase as large as 80 cm.
The plant life are scapose, having an individual central leafless hollow bloom stem (scape). Several blue-green or green, narrow, strap-shaped leaves happen from the light bulb. The plant stem bears a solitary blossom, but once in a while a cluster of blossoms (umbel). The plants, which are conspicuous and white or yellowish usually, sometimes both or seldom renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an outer ring composed of six tepals (undifferentiated sepals and petals), and a central disk to conical formed corona. The blooms may hang down (pendent), or be erect. You will discover six pollen bearing stamens encompassing a central style. The ovary is poor (below the floral parts) consisting of three chambers (trilocular). The berries consists of a dry out capsule that splits (dehisces) releasing numerous black seeds.
The bulb lies dormant after the leaves and flower stem die again and has contractile root base that draw it down further in to the soil. The flower leaves and stem form in the light, to emerge the next season. Most species are dormant from summer time to overdue winter, flowering in the spring and coil, though a few species are fall months flowering.
