Abstract
During a year's cycle the diatom vegetation of a salt spring ("Salzbrunnen") near Rothenkirchen (Hesse, Federal Republic of Germany) has been investigated. This spring discharges 4.8 l/min of sodium-calcium-chloride-sulphate enriched water. The sociological analysis shows a spring community characterized by the mesohalobous species Achnanthes grimmei (50% abundance) and Nitzschia frustulum var. subsalina (15% abundance). The third dominant is Synedra ulna (30% abundance), which is known for its wide ecological range. The community is described as an Achnanthes grimmei - N. subsalina synusia (sensu Du Rietz).
