Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
Limnophila sessiliflora is an aquatic plant native to Southeast Asia. The history of invasiveness is not documented. L. sessiliflora has been successfully introduced into parts of the southern United States and potentially elsewhere. The species was introduced as an ornamental. There are reports that the species may be a crop pest or interfere with navigation and water control but they were not backed by scientific investigation. Climate matching indicated the contiguous United States has a high climate match with already established L. sessiliflora populations in the southeastern United States. This amphibious plant is a federally and state listed noxious species. Certainty of this assessment is low. The overall risk assessment category is uncertain.
