Menyanthaceae
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 (e.g., '' Liparophyllum'') 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. Species of Menyanthaceae are found worldwide. The genera ''Menyanthes'' and ''Nephrophyllidium'' grow only in the northern hemisphere, while '' Liparophyllum'' and '' Villarsia'' occur only in the southern hemisphere. ''Nymphoides'' species have a cosmopolitan distribution. Menyanthaceae species are of economic importance as ornamental water garden plants, with ' ...

Villarsia
''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''. ''Villarsia'' is largely restricted to Australia, but some species are found in Southeast Asia, and '' V. capensis'' and others exist in South Africa.
