Potamogeton wrightii (Potamogetonaceae) naturalized in Ohio, U.S.A.



In 2021, an unknown Potamogeton species was discovered in Alum Creek Lake in central Ohio. After we were unable to identify the plants as any known North American species, we expanded our search to include all pondweed species and incorporated molecular data to aid in the identification. DNA sequences were obtained for the nuclear internal transcribed spacer (ITS) region and the plastid trnT-trnF region and compared against previously reported sequences for Potamogeton species. Morphological and molecular data consistently identified the plants as P. wrightii, a species native to eastern Eurasia and Malesia and not previously reported to be naturalized in North America.
