Nymphoides, or floatingheart, [1] is a genus of aquatic flowering plants in the family Menyanthaceae. The genus name refers to their resemblance to the water lily Nymphaea . 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.

Species of Nymphoides are sold as aquarium plants, including the "banana plant", N. aquatica and the "water snowflake", N. indica . Species native to the United States are N. cordata in the northeast and N. aquatica in the southeast. Nymphoides peltata is native to Europe and Asia, but can be found in the United States as an invasive aquatic weed. The non-native species N. cristata and N. indica also reportedly occur in Florida (Jacono 2000).

Nymphoides hydrophylla slim stem (spear) are used as vegetable at Meinong District, Kaohsiung, Taiwan.

Numerous species of Nymphoides grow in Australia, and others exist in Africa, America, and Asia.

Phyllanthus is the largest genus in the plant family Phyllanthaceae. Estimates of the number of species in this genus vary widely, from 750 to 1200. Phyllanthus has a remarkable diversity of growth forms including annual and perennial herbs, shrubs, climbers, floating aquatics, and pachycaulous succulents. Some have flattened leaflike stems called cladodes. It has a wide variety of floral morphologies and chromosome numbers and has one of the widest range of pollen types of any seed plant genus.

<span class="mw-page-title-main">Menyanthaceae</span> Family of flowering plants

Menyanthaceae is a family of aquatic and wetland plants in the order Asterales. There are approximately 60-70 species in six genera distributed worldwide. The simple or compound leaves arise alternately from a creeping rhizome. In the submersed aquatic genus Nymphoides, leaves are floating and support a lax, umbellate or racemose inflorescence. In other genera the inflorescence is erect and consists of one to many flowers. The sympetalous, insect-pollinated flowers are five-parted and either yellow or white. The petals are ciliate or adorned with lateral wings. Fruit type is a capsule.

<i>Villarsia</i> Genus of aquatic plants

Villarsia is a genus of aquatic flowering plants in the family Menyanthaceae. The genus is named for the French botanist Dominique Villars (1745–1814). Villarsia are wetland plants with basal leaves. The inflorescence is a branched panicle with numerous flowers. Flowers are five-parted, either yellow or white, and the petals are adorned with wings. A number of its Australian species were reassigned to Ornduffia.

<i>Anisomeles</i> Genus of flowering plants

Anisomeles is a genus of herbs of the family Lamiaceae and is native to China, the Indian Subcontinent, Southeast Asia, New Guinea, Australia, Madagascar, and some Pacific and Indian Ocean islands. Plants in the genus Anisomeles have small, flat, narrow elliptic to narrow e.g.-shaped leaves arranged in opposite pairs, the edges of the leaves sometimes wavy or serrated. The flowers are arranged in groups, with five sepals and five petals in two "lips", the lower lip with three lobes, the middle lobe much longer than the side lobes. There are four stamens that extend beyond the petals and a single style in a depression on top of the ovary. The fruit is a schizocarp with four nutlets containing small seeds.
