Ultraoligotrophic Lake

On the basis of the studied materials from the ultraoligotrophic lake Elgygytgyn (Chukotka), a rare for the flora of Russia diatom species Navicula schmassmannii was recorded. In the studied populations of the species a wide variability of morphological quantitative (valve length and width, the number of stria in 10 μm) and qualitative (the shape of the valve and the central area) features was marked. It made the basis for emending of the species diagnosis.
