The genus name Ludwigia is given in honor of Christian Gottlieb Ludwig (1709-1773). Ludwig was professor of Botany at the University of Leipzig in Germany. The University was founded in 1409 and is still in operation today with almost 30,000 students.
The species epithet peploides derives from the Greek "pepl" meaning "a gown, coat" and "oid" meaning "like, form, resembling" perhaps referring to the large floating mats the plant can form when left unchecked.
