|Proserpinaca pectinata in fruit|
Proserpinaca, commonly called mermaidweed is a genus of flowering plants in the watermilfoil family (Haloragaceae). It is a small genus, comprising only two to three species, all of which are native to eastern North America and the West Indies. All species in this genus are found in aquatic or terrestrial wetland habitats.
Two or three species are known from this genus, depending on the treatment. They are:
- Proserpinaca intermedia - Uncommon in the southeastern U.S.; intermediate in characters, and it is unclear if it is best treated as a hybrid
- Proserpinaca palustris - Widespread in eastern North America and the West Indies
- Proserpinaca pectinata - Native primarily to the Southeast Coastal Plain, with disjunct populations in middle Tennessee
