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.
Ottelia acuminata is a perennial freshwater aquatic plant species of conservation concern that is endemic to China. This species is harvested locally as an ornamental, medicinal, and edible plant. The history of invasiveness is classified as No Known Nonnative Population as no records of introduction outside of its native range were found. The overall climate match for the contiguous United States was low. There were areas of medium match in peninsular Florida, portions of the Southwest along the Untied States border with Mexico, and in the central portion of the Great Plains. The certainty of assessment is low due to a lack of information. The overall risk assessment category for O. acuminata is Uncertain.
