As our general herbarium colection is largely unmounted and therefore not ready to be studied, we would like to ask you to kindly announce your visit at least two weeks prior to your arrival. If you wish to examine material of larger genera, it would be better to give us one month to prepare the material. Otherwise we will not be able to grant you access to this part of the herbarium collection.
