原生地・分布（英語）:

説明（英語）: Genus of 50 species of slow-growing, rhizomatous, evergreen, marginal aquatic perennials from tropical S. and S.E. Asia. They are grown for their stiff, broadly ovate to lance-shaped, leathery leaves, which are mostly submerged. Minute, orange, red, or purple to almost black flowers are produced in a tubular spathe that projects above the surface of the water in mature plants. The flowers contain olfactory glands that give off a dung-like scent; this attracts insects, which crawl down the inside of the spathe, where they become trapped and pollinate the female flowers. In frost-prone areas, grow in a tropical aquarium or in the margins of an indoor pool in a warm greenhouse. In warmer areas, grow in the margins of an outdoor pool.

耐寒性（英語）: Frost tender.

栽培（英語）:

繁殖（英語）: Remove offsets in spring, or divide rhizomes in spring or early summer, and plant 1-2cm (1/2-3/4in) deep.

病害虫（英語）: Slight changes in external conditions, such as light and temperature, or in water chemistry, may cause the leaves to become soft and translucent.
