Blue lotus (Nymphaea nouchali caerulea)
Description
Water lilies are aquatic rhizomatous perennial herbs, sometimes with stolons, as well. The leaves grow from the rhizome on long petioles. Most of them float on the surface of the water. The blades have smooth or spine-toothed edges, and they can be rounded or pointed. The flowers rise out of the water or float on the surface, opening during the day or at night. Many species of Nymphaea display protogynous flowering. The temporal separation of these female and male phases is physically reinforced by flower opening and closing, so the first flower opening displays female pistil and then closes at the end of the female phase, and reopens with male stamens.Each has at least eight petals in shades of white, pink, blue, or yellow. Many stamens are at the center. Water lily flowers are entomophilous, meaning they are pollinated by insects, often beetles. The fruit is berry-like and borne on a curving or coiling peduncle.
