The botanical researcher and author Marietta Pallis (1882-1963) notes that her "...acquaintance with Plav dates from September 1912, when I went to Rumania to study the aquatic vegetation of the Danube valley and delta. I had for some years past been working at the vegetation of the Norfolk Broads, and it was with the object of gaining, for comparative purposes, some knowledge of similar localities and their vegetation that I decided to visit the Danube in Rumania, where it seemed to me probable that the most primitive aquatic vegetation in Europe would be found..."
