The high temperature inside the flower, which may be even 10 °C higher than the environmental one, the colour of the petals, the smell and the abundant sugary substance present, ensure that the pollinator remains long time inside the flower, thus remaining trapped when, by the end of the first night, the flower closes. The seeds are also used as food when roasted. At low water, the várzea has within it many lakes, and is traversed anastomosing large and small channels - paranas and furos, 1837.

The flowers are nocturnal, of 20-35 cm of diameter, solitary over the surface of the water, on a thorny peduncle also equipped with channels where air is present, have 4 brown sepals covered by thorns, 50 and more petals and up to about 200 stamina; the petals are cream white during the first night, pink on the second, then they finally close carrying the forming fruit to the bottom where it continues its ripening, for emerging again when completely ripe. The Victoria amazonica (Poepp.) Its leaves are rounded and upturned. J.C. Sowerby (1850) is a perennial, freshwater, rhizomatose, herbaceous plant with the rhizome rooted into the bottom sediment. 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. It is the largest member of the water lily family. eventually to produce 5 to 10 leaves a month 1.5 m to 2 m in diameter. The leaves are flat, peltate (with the petiole inserted almost at the centre of the lamina), with the margin raised at a right angle for a height of 5-15 cm, but two opposite slits for the outflow of the water; the raised edge hinders their overlapping, as often happens for the water lilies, allowing the leaves to present the same area to the photosynthesis. [2] 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. Under the surface, the leaves are red and have sharp spines that defend the plant from herbivorous fish.

The Amazon River has one of the most intact natural floodplains of any large Fieldwork is designed to map the floodplain and to characterize springs, seeps, and groundwater fed ponds with the goal of developing a A perfect example is the Amazon water lily (Victoria amazonica), which has adjusted its annual life cycle to the rise and fall of the rivers by growing rhizomes and new leaves from seeds, flowering at high water, fruiting as the water recedes, and surviving low water levels as seeds—each one surrounded by an impervious seed coat that protects against desiccation.

The following day, at dusk, the stigma is not any more receptive whilst the ripe pollen is released; the flower, at this stage, is not any more appetible for the pollinator, due to the colour of the petals, turned to pink, the absence of heat and of nourishment, and, as soon as the flower opens, it flies away, covered by pollen, towards another flower which has just opened its white petals and pollinates the same.
