Nymphaea Subg
''Nymphaea'' () is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, and some are weeds. Plants of the genus are known commonly as water lilies, or waterlilies in the United Kingdom. The genus name is from the Greek νυμφαία, ''nymphaia'' and the Latin ''nymphaea'', which means "water lily" and were inspired by the nymphs of Greek and Latin mythology. Description Vegetative characteristics Water lilies are aquatic, rhizomatous or tuberous, perennial or annual herbs with sometimes desiccation-tolerant, branched or unbranched rhizomes, which can be stoloniferous, or lacking stolons. The tuberous or fibrous roots are contractile. The leaves are mostly floating, but submerged and emergent leaves occur as well. The shape of the lamina can be ovate, orbicula ...
