The Reuss herbarium is a collection of c. 60 000 vascular plants of mainly European origin brought together in the mid-nineteenth century and kept in the Botanical Museum Berlin. This herbarium consists of specimens gathered by August Emanuel Reuss and his two sons August Leopold and Wilhelm Joseph and includes ample material purchased from different sources, notably the exchange club “Botanischer Tauschverein” in Vienna, and various exsiccata series. The collection also contains the voucher material referring to August Leopold Reuss's publications on the flora of what is now the north of the Czech Republic, the eastern fringe of Austria, the most western part of Croatia and the surroundings of Trieste in Italy. A considerable proportion of the Reuss herbarium originates from gardens, both botanic and private, in Prague, Vienna and elsewhere, and documents in certain cases their long-lost inventories. The complex background of the Reuss herbarium and its acquisition are elucidated, brief biographies of the key figures of the Reuss family with emphasis on their botanical activities are provided, and the names of the main collectors represented in the herbarium are listed.
