On Wikipedia

Hygrophila, commonly known as swampweeds, is a genus of flowering plants in the acanthus family, Acanthaceae. There are about 80 to 100 species, of which many are aquatic plants. The genus is distributed across the tropical and subtropical world. It is one of only two genera in its family that contains aquatic plants, the other being Justicia. The genus is treated in the tribe Hygrophileae, which is noted as being in need of revision at the genus level, meaning the current taxonomic boundaries of Hygrophila are likely to change in the future.
