Trapped In Time 86 The Daffodils Speak Part 2

"Daffodil" form

"Paperwhite" form

"Triandrus" form.

The predominant patterns are the 'daffodil' and 'paperwhite' forms, while the "triandrus" form is less common. Each corresponds to a different group of pollinators.

"The "daffodil" form, has a relatively short, broad or highly funnelform tube (funnel-like), which grades into an elongated corona, which is large and funnelform, forming a broad, cylindrical or trumpet-shaped perianth, generally solitary but rarely in inflorescences of 2–4 flowers. They have wide greenish floral tubes with funnel shaped bright yellow coronas. The six tepals sometimes differ in colour from the corona and may be cream coloured to pale yellow."

"The "paperwhite" form, including sections Jonquilla, Apodanthi and Narcissus, has a relatively long, narrow tube and a short, shallow, flaring corona. The flower is horizontal and fragrant."

"The "triandrus" form is seen in only two species, N. albimarginatus (a Moroccan endemic) and N. triandrus. It combines features of both the "daffodil" and "paperwhite" forms, with a well-developed, long, narrow tube and an extended bell-shaped corona of almost equal length. The flowers are pendent."

"The Androecium comprises six stamens in one to two rows (whorls), with the filaments separate from the corona, attached at the throat or base of the tube (epipetalous), often of two separate lengths, straight or declinate-ascending (curving downwards, then upwards). The anthers are basifixed (attached at their base)."

"The Gynoecium comprises the ovary which is inferior (below the floral parts) and trilocular (three chambered) and there is a pistil with a minutely three lobed stigma and filiform (thread like) style, which is often exserted (extending beyond the tube)."

"The fruit consists of dehiscent loculicidal capsules (splitting between the locules) that are ellipsoid to subglobose (almost spherical) in shape and are papery to leathery in texture."

"The fruit contains numerous subglobose seeds which are round and swollen with a hard coat, sometimes with an attached elaiosome. The testa is black[9] and the pericarp dry."

Alkaloids

As with all Amarylidaceae genera, Narcissus contains unique isoquinoline alkaloids. The first alkaloid to be identified was lycorine, from N. pseudonarcissus in 1877. These are considered a protective adaptation, and are utilised in the cla.s.sification of species. Nearly 100 alkaloids have been identified in the genus, about a third of all known Amaryllidaceae alkaloids, although not all species have been tested. Of the nine alkaloid ring types identified in the family, Narcissus species most commonly demonstrate the presence of alkaloids from within the Lycorine (lycorine, galanthine, pluviine) and h.o.m.olycorine (h.o.m.olycorine, lycorenine) groups. Hemanthamine, Tazettine, Narciclasine, Montanine and Galantamine alkaloids are also represented. The alkaloid profile of any plant varies with time, location, and developmental stage. Narcissus also contain fructans and low molecular weight glucomannan in the leaves and plant stems.

Fragrances

Fragrances are predominantly monoterpene isoprenoids, with a small amount of benzenoids, although N. jonquilla has both equally represented. Another exception is N. cuatrecasasii which produces mainly fatty acid derivatives. The basic monoterpene precursor is geranyl pyrophosphate, and the commonest monoterpenes are limonene, myrcene, and trans-β-ocimene. Most benzenoids are non-methoxylated, while a few species contain methoxylated forms (ethers), e.g. N. bugei. Other ingredient include indole, isopentenoids and very small amounts of sesquiterpenes. Fragrance patterns can be correlated with pollinators, and fall into three main groups.

History

The genus Narcissus was well known to the ancients. In Greek literature Theophrastus and Dioscorides described N. poeticus, although the exact species mentioned in cla.s.sical literature cannot be accurately established. Pliny the Elder later introduced the Latin form narcissus. These early writers were as much interested in the plant's possible medicinal properties as they were its botanical features and their accounts remained influential until at least the Renaissance. But it remained to Linnaeus to formally describe and name Narcissus as a genus in his Species Plantarum (1753) at which time there were six known species.

Modern

De Jussieu (1789) grouped Narcissus into a "family", which he called Narcissi. This was renamed Amaryllideae by Jaume Saint-Hilaire in 1805, corresponding to the modern Amaryllidaceae. For a while Narcissus was considered part of Liliaceae, but then the Amaryllidaceae were split off from it.

Subdivision

The infrageneric phylogeny of Narcissus still remains relatively unsettled, the taxonomy having proved complex and difficult to resolve, due to the diversity of the wild species, the ease with which natural hybridization occurs, and extensive cultivation and breeding accompanied by escape and naturalisation. Consequently, the number of accepted species has varied widely.

It was not till the work of Baker that the wild species were all grouped as sections under one genus, Narcissus. There were many others like Webb, Graham and Barrett (2004) who tried to cla.s.sify them.

List of Narcissus species

N. major, N. triandrus and N. jonquilla. Encyclopaedia Londinensis 1819

Estimates of the number of species in Narcissus have varied widely, from anywhere between 16 and almost 160, even in the modern era. Linnaeus originally included six species in 1753, by 1784 there were fourteen by 1819 sixteen, and by 1831 Adrian Haworth had described 150 species.

Much of the variation lies in the definition of species. Thus, a very wide view of each species, such as Webb's results in few species, while a very narrow view such as that of Fernandes results in a larger number. Another factor is the status of hybrids, with a distinction between "ancient hybrids" and "recent hybrids". The term "ancient hybrid" refers to hybrids found growing over a large area, and therefore now considered as separate species, while "recent hybrid" refers to solitary plants found amongst their parents, with a more restricted range.

Evolution

Within the Narcisseae, Narcissus (western Mediterranean) diverged from Sternbergia (Eurasia) some time in the Late Oligocene to Early Miocene eras, around 29.3–18.1 Ma. Later the genus divided into the two subgenera (Hermione and Narcissus) between 27.4–16.1 Ma. The divisions between the sections of Hermione then took place during the Miocene period 19.9–7.8 Ma. Narcissus appears to have arisen in the area of the Iberian peninsula, southern France and north-western Italy. Subgenus Hermione in turn arose in the southwestern mediterranean and north west Africa.

The derivation of the Latin narcissus is unknown, but is frequently linked to the myth of Narcissus, who became so obsessed with his own reflection in water that he drowned and the narcissus plant sprang from where he died. There is no evidence for the flower being named for the youth. Narcissus poeticus which grows in Greece, has a fragrance that has been described as intoxicating. Pliny wrote that the plant was named for its fragrance (ναρκάω narkao, "I grow numb" ), not the The name Narcissus was not uncommon for men in Roman times.

Daffodil

The name "daffodil" is derived from "affodell", a variant of asphodel. The narcissus was frequently referred to as the asphodel. Asphodel in turn appears to come from the Greek "asphodelos" (Greek: ἀσφόδελος). The reason for the introduction of the initial "d" is not known. From at least the 16th century, "daffadown dilly" and "daffydowndilly" have appeared as alternative names. Other names include "Lent lily".
