A SINGLE SPECIES
Aldrovanda vesiculosa and some red coloured variations
Observed in India in the sixteenth century, called "Duckweed palutris indica" by L. Plukenet in 1696. Almost fifty years later, G. Monti named it "Aldrovandia vesiculosa" in honor of U. Aldrovandi, an Italian naturalist. Even if there is a removal of the 'i', now we adopt the spelling "Aldrovanda vesiculosa" after the index Nominorum Genericorum. In 1753, C. Linnaeus's spelled this name in his book Species plantarun.
From Europe to Africa, Asia, Japan and Australia ; despite an immense area, the sites are scattered and the plant is exctinct in many countries.
Of a quite tropical nature, the Aldrovanda remains a relic of warmer period in cold regions. It likes sweet and calm waters, ditches, ponds, rivers arms with acidic pH. This plant is related to aquatic vegetation, as well as deciduous trees, whose leaves contribute, as it decays in water, the development of humic material necessary for prey and the plant.
Small floating aquatic plant without roots, measuring 10-50 cm long. The green leaves, are 7 or 8 and are combined in an alternating whorls.
