Victoria amazonica is a species of flowering plant, the largest of the water lily family Nymphaeaceae. It is the national flower of Guyana. Its native regions where it can be found are in Guyana and tropical South America.
The Victoria amazonica has very large leaves, up to 3 m (10 ft) in diameter, that float on the water's surface on a submerged stalk, 7–8��m (23–26 ft) in length. It is the largest waterlily in the world. V. amazonica is native to the shallow waters of the Amazon River basin, such as oxbow lakes and bayous. In their native habitat, the flowers first begin to open as the sun starts to set and can take up to 48 hours to fully open. These flowers can grow up to 40 cm (16 in) in diameter. Each plant will continue to produce flowers for a full growing season and they have co-evolved with a species of scarab beetle of the genus Cyclocephala, to improve its pollination. All the buds in a single patch will begin to open at the same time and as they do, they give off a fruity smell. At this point in time the flower petals are white and the beetles become attracted to both the colour and the smell of the flower. By nightfall the flower closes, the oder stops being emitted, and the beetle becomes trapped inside the carpellary appendages inside the flower. Here, the stamens are protected by the paracarpels and for the next day the flower continues to remain closed. The cavity in which the beetle is trapped is composed of a spongy, starchy tissue that provides nourishment for the beetle. During this time, anthocyanins start to be released by the plant, which in turn changes the petals from white to a reddish pink colour, a sign that the flower will have been pollinated. As the beetle munches away inside the flower, the stamens fall inward and the anthers, which have already fallen, drop pollen on the stamens. During the evening of the second day, the flowers will have opened enough to release the beetle and as it pushes its way through the stamens it becomes covered in pollen. These insects will then go on to find a newly opened water lily and cross-pollinate it with the pollen they are carrying from the previous flower. This process was described in detail by Sir Ghillean Prance and Jorge Arius.
The species is a member of the genus Victoria, placed in the family Nymphaeaceae or, sometimes, in the Euryalaceae. The first published description of the genus was by John Lindley in October 1837, based on specimens of this plant returned from British Guiana by Robert Schomburgk. Lindley named the genus after the newly ascended Queen Victoria, and the species Victoria regia. The spelling in Schomburgk's description in Athenaeum, published the month before, was given as Victoria Regina. Despite this spelling being adopted by the Botanical Society of London for their new emblem, Lindley's was the version used throughout the nineteenth century.
An earlier account of the species, Euryale amazonica by Eduard Friedrich Poeppig, in 1832 described an affinity with Euryale ferox. A collection and description was also made by the French botanist Aimé Bonpland in 1825. In 1850 James De Carle Sowerby recognized Poeppig's earlier description and transferred its epithet amazonica. The new name was rejected by Lindley. The current name, Victoria amazonica, did not come into widespread use until the twentieth century.
Victoria regia, as it was named, was described by Tadeáš Haenke in 1801. It was once the subject of rivalry between Victorian gardeners in England. Always on the look out for a spectacular new species with which to impress their peers, Victorian "Gardeners" such as the Duke of Devonshire, and the Duke of Northumberland started a well-mannered competition to become the first to cultivate and bring to flower this enormous lily. In the end, the two aforementioned Dukes became the first to achieve this, Joseph Paxton (for the Duke of Devonshire) being the first in November 1849 by replicating the lily's warm swampy habitat (not easy in winter in England with only coal-fired boilers for heating), and a "Mr Ivison" the second and more constantly successful (for Northumberland) at Syon House.
The species captured the imagination of the public, and was the subject of several dedicated monographs. The botanical illustrations of cultivated specimens in Fitch and W.J. Hooker's 1851 work Victoria Regia received critical acclaim in the Athenaeum, "they are accurate, and they are beautiful". The Duke of Devonshire presented Queen Victoria with one of the first of these flowers, and named it in her honour. The lily, with ribbed undersurface and leaves veining "like transverse girders and supports", was Paxton's inspiration for The Crystal Palace, a building four times the size of St. Peter's in Rome.
