Biographical / Historical

The Academy's Diatom Herbarium, one of the two largest in the world, is a primary source of taxonomic and ecological information. It includes approximately 220,000 slides (curated and non-curated), of which about 5,000 are types. Materials include both fossil and recent diatoms collected from fresh, brackish, and marine habitats. The herbarium has a long history, with many specimens dating from the 19th century or even earlier.
