The herbarium is extremely valuable because it includes a great number of authentic specimens (standard samples that are regarded as types when new taxa are described). In oblique cases, such samples serve as evidence for the validation of scientific names given to plants in the eighteenth and nineteenth centuries. Hoffmann's herbarium - one of the oldest collections of dried plants in the world - is unique and will continue to serve science for a long time to come.
