原生地・分布（英語）:

説明（英語）: Genus of 8 species of floating, aquatic ferns found in lakes, ponds, and slow-flowing streams in both hemispheres. They have pinnately branched, floating rhizomes, with frail roots, producing 2-lobed, light green, scale-like fronds, which turn reddish brown in autumn. On a pool, they provide fast-growing surface cover, which partially suppresses algae and helps clear the water. In frost-prone areas only A. filiculoides is suitable for outdoor pools; grow tender species in indoor pools in a cool or temperate conservatory or terrarium.

耐寒性（英語）: Half hardy to frost tender.

栽培（英語）:

繁殖（英語）: Scatter small bunches of young plants on the water surface in early summer.
