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 Nymphoides being most commonly traded. The practice of growing non-native water plants has led to several species becoming naturalized or invasive.

Dimorphic heterostyly occurs in all genera but Liparophyllum . In addition, four species of Nymphoides are dioecious.^[2]
