A diatom species Navicula peroblonga, which is rare for the flora of Russia, has been detected in Lake Podskalnoe (Yakutia). Its morphology was studied using scanning electron microscopy. A number of quantitative characteristics (valve width, number of striae and lineolae in 10 µm) and literature data showed that the species exhibits a wider variability, which made it possible to specify its description.
