Complete answer:
Victoria amazonica is a flowering plant species, the largest species of the Nymphaeaceae family of water lilies. This species of water lilies has very large leaves which are up to 3 m in diameter and they float on the surface of water and have submerged stalks which are about 78 m in length.
This species of water lilies is called Victoria regia after the name of Queen Victoria, but then this name was superseded. V. amazonica species is a native plant to the shallow waters of the Amazon river basin like oxbow lakes and bayous. It is also depicted in the Guyanese coat of arms.
The flowers of the plant are white in color the first night when they open and then become pink on the second night. They are found to be up to 40 cm in diameter, and get pollinated by beetles. The process of pollination was first described in detail by Sir Ghillean Prance and Jorge Arius. It is the largest known waterlily in the world.
Victoria regia has the hardest and thickest, largest leaves of the plant kingdom.
Musa paradisiaca is a plant which has spirally arranged large oval leaves and has a mid-rib with parallel side veins which extends up to the margin; the lamina of the plant is torn into ribbon shape because of the mechanical injury.
Nelumbiumnucifera has floating leaves of oval or oblong shape which are up to 60 cm in diameter.
A species of Amorphophallus known as A. titanium has the world's largest unbranched inflorescence which can reach a height of about 2.5 m and a width of about 1.5 m.
