Water Lilies, (Nymphaeaceae), 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. Each has at least 8 petals in shades of white, pink, blue, or yellow. There are many stamens at the center. Water-lily flowers are entomophilous, pollinated by insects, often beetles. The fruit is berry-like and borne on a curving or coiling peduncle. In Thailand, water lilies are pretty much lumped in with lotus and called Bua as well.
