| 説明 | Peradeniya Botanical Gardens near Kandy, Sri Lanka.Nymphoides, or floatingheart, is a genus of aquatic flowering plants in the family Menyanthaceae.Nymphoides are aquatic plants with submerged roots and floating leaves that hold the small flowers above the water surface. Flowers are sympetalous, most often divided into five lobes (petals). The petals are either yellow or white, and may be adorned with lateral wings or covered in small hairs. The inflorescence consists of either an umbellate cluster of flowers or a lax raceme, with internodes occurring between generally paired flowers.Nymphoides hydrophylla, commonly known as crested floating-heart, is native to tropical Asia. It has cordate floating leaves that support a lax inflorescence of dainty white flowers with fringed petal margins. Its slim stem (spear) is edible, and is used as vegetable in Taiwan, mostly produced at Meinong District, Kaohsiung.The flowers of Nymphoides hydrophylla are gynodioecious. The fruit is a capsule bearing many flattened seeds.The plants are commonly sold for use in ornamental water gardens. Outside their native range they can escape cultivation and become nuisance weeds, particularly in Florida. They are not killed by freezing, and have been reported in Lake Marion, South Carolina. |
