Potamogeton ×tosaensis Kadono, Horii & Yamanouchi (Potamogetonaceae) is described here as a new hybrid. Although similar to P. octandrus, it is morphologically distinguishable in several traits. Most conspicuous of these are the connate stipules and fusiform turion bearing one acerose leaf. The plants were found only in and around Kochi City, Shikoku. Potamogeton octandrus and P. pusillus are the putative parents.
