CommentsA second known location is 4-miles upstream- it is likely that M. keisak occurs between these locations; It is also likely that it can be found all along the Wolf River into Mississippi. It was not found along the Wolf River at William B. Clark State Natural Area on Sept. 14, 2018. The natural area is approximately 12 miles downstream from Bateman Road. M. keisak is likely to cause the eradication of the state rare plant, Heteranthera multiflora at this site.
