Giant Amazonian Water Lillies - Researchers studying giant Amazonian waterlilies have unravelled the engineering enigma behind the largest floating leaves in nature . In a study published today in Science Advances , researchers found that the distinctive pattern on the underside of the gargantuan leaves is the secret to the success of the giant Amazonian waterlily (genus Victoria ). The criss-cross framework makes up the vascular structure of the lily pad (or leaf), supporting its large surface area and keeping it afloat. The giant leaves can grow 40cm a day, reaching nearly 3m in diameter - ten times larger than any other species of waterlily - and carry the weight of a small child. Dr Finn Box, Royal Society University Research Fellow, School of Physics and Astronomy at The University of Manchester explained: "Leaf size is usually restricted mechanically by the expense of maintenance. A larger surface area for photosynthesis uses more of the plant's energy to maintain. The structure and load-bearing properties of the giant Amazonian waterlily give it a competitive edge: high strength at low cost." Dr Chris Thorogood, Deputy Director at the University of Oxford Botanic Garden said: "I used to marvel at this extraordinary plant on childhood trips to botanic gardens.
