Narcissus Flower Definition Clinic

Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plant life in the Amaryllidaceae (amaryllis) family. Various common brands including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are 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 blossoms are generally white or yellow (orange or green in garden varieties), with either even or contrasting colored corona and tepals.

Narcissus were well known in historical civilisation, both and botanically medicinally, but formally explained by Linnaeus in his Types Plantarum (1753). The genus is generally thought to have about ten parts with around 50 species. The amount of varieties has assorted, depending about how they are classified, anticipated to similarity between varieties and hybridization. The genus arose some right time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the true name Narcissus is mysterious, but it is linked to a Greek expression for intoxicated (narcotic) and the myth of the children of this name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.

The varieties are local to meadows and woods in southern Europe and North Africa with a center of diversity in the Western Mediterranean, the Iberian peninsula particularly. Both wild and cultivated plants have naturalised widely, and were created into 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, 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 hundred years and by the overdue 19th century were an important commercial crop centred mainly on holland. Today narcissi are popular as lower blooms so when ornamental plant life in private and general public gardens. 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 unintentionally. 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 literature and fine art, narcissi are associated with a true number of themes in several cultures, ranging from death to good fortune, and as icons of planting season. The daffodil is the countrywide bloom of Wales and the sign of cancer charities in many countries. The looks of the outdoors flowers in spring is associated with festivals 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 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on species. Dwarf types such as N. asturiensis have a maximum height of 5-8 cm, while Narcissus tazetta might expand as large as 80 cm.

The crops are scapose, having an individual central leafless hollow bloom stem (scape). Several green or blue-green, slim, strap-shaped leaves happen from the light bulb. The plant stem usually bears a solitary blossom, but once in a while a cluster of bouquets (umbel). The bouquets, which are 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 tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical molded corona. The plants may suspend down (pendent), or be erect. A couple of six pollen bearing stamens bordering a central style. The ovary is second-rate (below the floral parts) comprising three chambers (trilocular). The berries involves a dry out capsule that splits (dehisces) liberating numerous black seed products.

The bulb is situated dormant after the leaves and bloom stem die back again and has contractile root base that move it down further into the soil. The flower stem and leaves form in the bulb, to emerge the following season. Most types are dormant from summer season to overdue winter, flowering in the planting season, though a few species are fall flowering.
