Because the name Potamogeton ×babingtonii has been synonymised with P. ×angustifolius , no valid binominal exists for the hybrid P. lucens×praelongus . A morphological and anatomical study presented here demonstrates that specimens regarded by Hagström as Potamogeton ×babingtonii f. danicus really represent the hybrid between P. lucens and P. praelongus . As a consequence, a new binominal for this hybrid is introduced and its basionym Potamogeton ×babingtonii f. danicus is lectotypified. Morphological and anatomical characters of Potamogeton ×jutlandicus nom. nov. (= P. lucens×praelongus ) are provided and its taxonomic delimitation is discussed.
