This sub-collection includes dried and alcohol preparations as well as large-format pieces from various plant groups, including original collections but also demonstration pieces. Important parts of the alcohol collection are the mushrooms collected by A. Möller in Brazil and by F. Eichelbaum in Tanzania. Another focus is on the Aizoaceae from the H.E.K. Hartmann collection and collections of H.K.A. Winkler from Borneo and J. Mildbraed from Cameroon.
