原生地・分布（英語）: N.temperate, cold

説明（英語）: Genus of 25 species of deciduous, submerged, aquatic perennials, mainly from temperate regions of the N. hemisphere. They have stout, creeping rhizomes, and both leathery floating leaves and membranous submerged leaves. In summer, they bear solitary, almost spherical flowers, which are held above the water surface. The flowers are followed by berry-like, ovoid to flask-shaped fruits. Generally more vigorous than water lilies (Nymphaea), they thrive in deeper, cooler water, forming robust groups of foliage on large natural lakes, where they may cover the water surface completely.
