Visiting the collections
All areas of the herbarium are open to scientists, where feasible, but we do ask visitors to contact us in advance of the intended visit.
About one sixth of the collection was destroyed during the Second World War. Only a few specimens remain in the affected families, therefore it is advised to send an email to check if the requested specimen(s) still exist.
The diatom collection by Grunow is only accessible to registered visitors; please email Dr. Anton Igersheim, Curator of the Cryptogam herbarium.
It is possible to compare the specimens in W with your own material but, for security reasons, fresh or dried specimens must be declared and receive a deep-freezing treatment before entering the herbarium. In such instances, the material in question must arrive two weeks before the proposed visit.
Additionally, a few days before and after the general fumigations (twice a year: 6th of May 2016 and 26th of August 2016), the herbarium is closed to all guests and staff.
It is possible to find numerous specimens, including scans of type specimens on the virtual herbaria website. Scans may also be requested by contacting us. Photographs of plants of the Austrian Flora can be found here.
There is also the possibility to request loans of specific specimens by contacting the relevant curator.
