The stonewort (Characeae) herbarium of the Botanical Institute Greifswald


M. Schnittler, S. Starke

Among the collections in the botanical museum (Starke & Schnittler 2009) we also inherited a remarkable collection of algae. Comprising more than 30,000 accessions, this collection helds a number of types, together with several exsiccate series. Among the macroscopic algae, the stoneworts (Characeae) are represented best in our collection, since the Baltic Sea with its coastal lagoons is a centre of diversity in this group, which comprises about 40 taxa in Germany. The stonewort collection was curated and digitalized by our late colleague Christian Blümel (1971-2006) in the frame of the ELBO-Project (Development of guidelines for quality assessment of brackish waters of the German Baltic Sea coast according to the EC water quality guideline).
