Collections and databases
The Herbarium Hamburgense preserves c. 1.8 Mill sheets of dried plants and holds separate bulky specimens and alcohol collections. Type specimens are of particular importance for a stable plant taxonomy and nomenclature and serve as reference vouchers. The herbarium holds a large number of type specimens especially from tropical regions such as Brazil (E. ULE, A. MÖLLER), Bolivia (O. BUCHTIEN), Borneo (H. WINKLER, M.S. CLEMENS), India (D. BRANDIS), Arabia (H. v. WISSMANN & C.A. RATHJENS), Australia and Polynesia (L. PREISS, A. DIETRICH, E. GRAEFFE), and Africa (G. ZENKER, J. MILDBRAED, G.H.W. SCHIMPER, M. DINKLAGE, F. STUHLMANN, K. DINTER, R. SCHLECHTER, J.F. DRÈGE, C.F. ECKLON & C.L.P. ZEYHER). There are aaproximately 40.000 type sheets from all plant groups. Type scans and metadata are made successively available to the internationation taxonomic community using online databases.
The Herbarium Hamburgense is taking over scientifically documented plant collections. We are also offering duplicates for exchance, e.g. Amalie DIETRICH (Queensland), Hans WINKLER (Borneo), Otto BUCHTIEN (Bolivia), Tassilo FEUERER (Bolivia), Charles BOCK (Juan Fernandez), Hans HALLIER f.
