Narcissus /n?:r's?s?s/ is a genus of predominantly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common titles 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 pink in garden kinds), with either standard or contrasting colored corona and tepals.
Narcissus were popular in ancient civilisation, both medicinally and botanically, but formally explained by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten portions with approximately 50 species. The true amount of species has assorted, depending on how they are labeled, a consequence of to similarity between hybridization and species. The genus arose some time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The exact origin of the name Narcissus is unidentified, but it is often associated with a Greek word for intoxicated (narcotic) and the myth of the youngsters of that name who fell in love with his own reflection. The English expression 'daffodil' appears to be produced from "asphodel", with which it was commonly likened.
The types are local to meadows and woods in southern European countries and North Africa with a center of diversity in the Traditional western Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were presented in to the ASIA to the tenth century 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 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 after the 16th century and by the late 19th hundred years were an important commercial crop centred primarily on the Netherlands. Narcissi are popular as slice blooms so that as ornamental crops in private and general 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 shapes and colours. Like other members of the family, narcissi create a 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 in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in books and art, narcissi are associated with a true number of themes in different cultures, ranging from fatality to good fortune, and as icons of springtime. The daffodil is the countrywide blossom of Wales and the mark of tumors charities in many countries. The looks of the outdoors flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying again after flowering with an underground storage bulb. They regrow in the following yr from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm with regards to the species. Dwarf varieties such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta may expand as 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 come up from the light. The flower stem bears a solitary blossom, but sometimes a cluster of plants (umbel). The flowers, that happen to be conspicuous and white or yellowish usually, both or rarely renewable sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an external ring made up of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The blossoms may suspend down (pendent), or be erect. You will discover six pollen bearing stamens encircling a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruit contains a dry out capsule that splits (dehisces) liberating numerous black seed products.
The bulb is situated dormant following the leaves and bloom stem die again and has contractile origins that take it down further in to the soil. The rose leaves and stem form in the bulb, to emerge the next season. Most species are dormant from summertime to overdue winter, flowering in the springtime, though a few types are autumn flowering.
