原生地・分布（英語）:

説明（英語）: Genus of about 30 species of submerged aquatic annuals from still or slow-moving water in C. Europe, E. Asia, and Africa. The creeping, floating stems bear linear submerged leaves and rosettes of ovate or almost triangular to diamond-shaped, toothed, mottled floating leaves, hairy beneath, with spongy, swollen leaf-stalks. Small, solitary, tubular, white or lilac flowers are followed by inflated, spiny fruits. In frost-prone areas, grow in baskets in a cold-greenhouse pool, or float rosettes on the surface of an out-door pool after last frosts. In warmer climates, grow in an outdoor pool.

耐寒性（英語）: Half hardy to frost tender.
