Narcisos ibéricos en Flora Silvestre del Mediterráneo occidental

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 known members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted with a cup- or trumpet-shaped corona. The flowers are generally white or yellowish (orange or pink in garden types), with either standard or contrasting colored tepals and corona.

Narcissus were well known in early civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten portions with about 50 species. The number of species has varied, depending on how they are categorised, a consequence of to similarity between hybridization and species. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise origin of the true name Narcissus is unidentified, but it is associated with a Greek word for intoxicated (narcotic) and the myth of the junior of that name who fell in love with his own representation. The English word 'daffodil' is apparently produced from "asphodel", with which it was commonly likened.

The types are indigenous to meadows and woods in southern Europe and North Africa with a centre of variety in the American Mediterranean, the Iberian peninsula particularly. Both cultivated and wild plants have naturalised widely, and were launched into the Far East to the tenth hundred years prior. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are also insect-pollinated. 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 increasingly popular in Europe after the 16th century and by the past due 19th hundred years were an important commercial crop centred mainly on holland. Today narcissi are popular as slash blooms as ornamental crops 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 categorised into divisions, covering a wide range of shapes and colours. Like other members with their family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested inadvertently. This property has been exploited for medicinal use within traditional healing and has resulted in the production of galantamine for the treatment of Alzheimer's dementia. Long celebrated in books and fine art, narcissi are associated with a number of themes in different cultures, ranging from death to good fortune, and as symbols of springtime. The daffodil is the countrywide bloom of Wales and the symbol of cancer charities in many countries. The appearance of the crazy flowers in planting season 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 time from brown-skinned ovoid light bulbs with pronounced necks, and reach levels of 5-80 cm with respect to the species. Dwarf types such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as extra tall as 80 cm.

The crops are scapose, having a single central leafless hollow bloom stem (scape). Several green or blue-green, narrow, strap-shaped leaves happen from the light. The vegetable stem usually bears a solitary blossom, but occasionally a cluster of flowers (umbel). The flowers, 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 made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang down (pendent), or be erect. You will discover six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) comprising three chambers (trilocular). The fruit consists of a dry out capsule that splits (dehisces) releasing numerous black seed products.

The bulb sits dormant after the leaves and bloom stem die again and has contractile roots that draw it down further in to the soil. The blossom stem and leaves form in the bulb, to emerge the next season. Most kinds are dormant from summer time to overdue winter, flowering in the spring and coil, though a few varieties are fall flowering.
