Snowdrop

Galanthus (Snowdrop; Greek gála "milk", ánthos "flower") is a small genus of about 20 species of bulbous herbaceous plants in the family Amaryllidaceae, subfamily Amaryllidoideae. Most flower in winter, before the vernal equinox (20 or 21 March in the Northern Hemisphere), but certain species flower in early spring and late autumn.

 

Snowdrops are sometimes confused with their relatives, snowflakes, which areLeucojum and Acis species.

 

 

Ecology

 

Distribution

 

Galanthus nivalis is the best-known and most widespread representative of the genus Galanthus. It is native to a large area of Europe, stretching from the Pyrenees in the west, through France and Germany to Poland in the north, Italy, Bulgaria, Northern Greece, Ukraine, and European Turkey. It has been introduced and is widely naturalised elsewhere. Although it is often thought of as a British native wild flower, or to have been brought to the British Isles by the Romans, it was probably introduced around the early sixteenth century and is currently not a protected species in the UK.

Most other Galanthus species are from the eastern Mediterranean, though several are found in southern Russia, Georgia and Azerbaijan.

 

Conservation

 

Some snowdrop species are threatened in their wild habitats, and in most countries it is now illegal to collect bulbs from the wild. Under CITES regulations, international trade in any quantity of Galanthus, whether bulbs, live plants or even dead ones, is illegal without a CITES permit. This applies to hybrids and named cultivars as well as species. CITES does, however, allow a limited trade in wild-collected bulbs of just three species (G. nivalis, G, elwesii and G. woronowii) from Turkey and Georgia.

 

 

Description

 

All species of Galanthus are perennial, herbaceous plants which grow from bulbs. Each bulb generally produces just two or three linear leaves and an erect, leafless scape(flowering stalk), which bears at the top a pair of bract-like spathe valves joined by a papery membrane. From between them emerges a solitary, pendulous, bell-shaped white flower, held on a slender pedicel. The flower has no petals: it consists of six tepals, the outer three being larger and more convex than the inner series. The six anthers open by pores or short slits. The ovary is three-celled, ripening into a three-celled capsule. Each whitish seed has a small, fleshy tail (elaiosome) containing substances attractive to antswhich distribute the seeds. The leaves die back a few weeks after the flowers have faded.

The inner flower segments are usually marked with a green, or greenish-yellow, bridge-shaped mark over the small "sinus" (notch) at the tip of each tepal.

An important feature which helps to distinguish between species (and to help to determine the parentage of hybrids) is their "vernation" (the arrangement of the emerging leaves relative to each other). This can be "applanate", "supervolute" or "explicative". In applanate vernation the two leaf blades are pressed flat to each other within the bud and as they emerge; explicative leaves are also pressed flat against each other, but the edges of the leaves are folded back or sometimes rolled; in supervolute plants one leaf is tightly clasped around the other within the bud and generally remains at the point where the leaves emerge from the soil.

 

Cultivation and uses

 

Propagation

 

Propagation is by offset bulbs, either by careful division of clumps in full growth ("in the green"), or removed when the plants are dormant, immediately after the leaves have withered; or by seeds sown either when ripe, or in spring. Professional growers and keen amateurs also use such methods as "twin-scaling" to increase the stock of choice cultivars quickly.

 

Active substances

 

It was suggested by Andreas Plaitakis and Roger Duvoisin in 1983 that the mysterious magical herb moly that appears inHomer's Odyssey is actually snowdrop. An active substance in snowdrop is called galantamine, which, as anticholinesterase, could have acted as an antidote to Circe's poisons.

 

Snowdrops contain also an active lectin or agglutinin named GNA for Galanthus nivalis agglutinin.

 

In 1995 Árpád Pusztai genetically modified potatoes with the GNA gene, which work he discussed on a radio interview in 1998 and published in the Lancet in 1999. In 1998 said in an interview on a World in Action programme that his group had observed damage to the intestines and immune systems of rats fed the genetically modified potatoes. He also said "If I had the choice I would certainly not eat it", and that "I find it's very unfair to use our fellow citizens as guinea pigs". These remarks started the so-called Pusztai affair.

 

 

Media

 

William Wordsworth, the Two-Part Ballad: "I began / My story early, feeling, as I fear, / The weakness of a human love for days / Disowned by memory, ere the birth of spring / Planting my snowdrops among winter snows" (ll. 445-59).

 

Snowdrops feature in Seamus Heaney's poem Mid-term Break in the context of mourning a dead infant.

 

In the anime film Twelve Months (Sekai meisaku dowa mori wa ikiteiru in Japan), a greedy queen decrees that a basket of gold coins shall be rewarded to anyone who can bring her galanthus flowers in the dead of winter. A young girl named Anya is sent out during a snow storm by her cruel stepmother and find the spirits of the 12 months of the year, who take pity on her and not only save her from freezing to death, but make it possible for her to gather the flowers even in winter

 

"Snowdrops" was the nickname that the British people gave during the Second World War to the military police of theUnited States Army (who were stationed in the UK preparatory to the invasion of the continent) because they wore a white helmet, gloves, gaiters, and Sam Browne belt against their olive drab uniform

 

In Jacqueline Carey's series of novels set in Terre d'Ange, snowdrops are distilled to create a beverage called joie that is drunk on the Longest Night (Winter Solstice). In Naamah's Kiss, one of the characters makes a tonic from snowdrops that acts as an aphrodisiac, and the protagonist Moirin takes snowdrops from Terre d'Ange (based on France) and plants them in a mountain in Ch'in (based on China).

 

The short story The Snowdrop by Hans Christian Andersen follows the fate of a snowdrop from a bulb striving towards the light to a picked flower placed in a book of poetry.

 

The poet, Ambrosius Stub, is compared to the flower—as a summer gauk (fool), born before his time.
