Caldesia is a genus of aquatic plants. It includes three living species widespread across Europe, Asia, Africa and Australia.[1][2][3] The genus "has an extensive Oligocene through Pleistocene fossil record in Eurasia,"[4] and has been found in fossil strata of the United States (Idaho and Vermont) as well. Ten fossil species have been described for the genus.
