The paper deals with problems of taxonomy, reproduction, and distribution of the diatom Nitzschia longissima. Based on the analysis of literature data, as well as studying the type material and 36 clones collected on the Atlantic coast of France and in the Black Sea (region of Karadag), the authors propose to apply N. longissima to the concept sensu stricto, which, in their opinion, will eliminate many problems that have accumulated in the identification of this species.
