Menyanthaceae is a family of aquatic and wetland plants in the order Asterales. There are approximately 60 to 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 t

Liparophyllum is a genus of aquatic flowering plants in the family Menyanthaceae. The name Liparophyllum comes from the Greek words liparos, meaning "fat, shiny or oily", and phyllon, meaning "leaf". They are rhizomatous wetland plants with alternate linear leaves. Flowers occur singly, and are five-parted and white.

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.

Nephrophyllidium is a monotypic genus of aquatic flowering plants in the family Menyanthaceae. The sole species is Nephrophyllidium crista-galli. They are wetland plants with basal reniform and crenate leaves. Flowers are five-parted and white, and the petals are adorned with lateral wings and a midline keel. Nephrophyllidium is most nearly related to Menyanthes, which is very similar in habit. The genus name is derived from the kidney-shaped leaves ( = kidney and phyllon = leaf), and the specific epithet refers to the curled petal edges ( = cockscomb).
