ABSTRACT
Luronium natans (L.) Raf. is a very rare species in Europe. New stations of L. natans were found in the Pomeranian Lakeland (NW Poland) in 2017 and 2019: Lake Lubowisko – ATPOL square CB 0643; and Lake Pijawka – ATPOL square CB 5127. In lake Lubowisko it was found at 0.5–0.6 m depth (water pH 8.07, conductivity 190 μS cm−1, calcium concentration 39.8 mg Ca dm−3). In lake Pijawka, L. natans occupied the northern and eastern shores. The water is acidic and poor in dissolved salts, including calcium salts. In lake Pijawka the plants occur together with mosses (Warnstorfia exannulata, Sphagnum denticulatum).
