原生地・分布（英語）:

説明（英語）: Genus of 65 species of rhizomatous, terrestrial, amphibious, and aquatic perennial ferns from warm-temperate Europe, tropical W. Africa, N. Asia, Australia, and E. USA. They grow in large numbers, mainly beside rivers, but also in lakes, where the elongated rhizomes grow upwards, producing a canopy of surface leaves that develop a terrestrial form if the water recedes. Triangular to ovate, 4-lobed leaves each bear a spore case at the base, and close up at night when submerged. Grow at the margins of a pool. In frost-prone areas, grow the tender species in an indoor pool in a warm greenhouse or conservatory, or in a tropical aquarium; M. quadrifolia is suitable for a cold-water aquarium.

耐寒性（英語）: Fully hardy to frost tender.
