We are happy to receive donations of specimens that are vouchers for scientific studies, have historical significance, or enrich our taxonomic or geographical representation. These are expected to have been collection with the appropriate permission and/or official permits. We only accept donations for which ownership can be transferred to the Herbarium. Please contact the Curators about depositing specimens in our collection.
The OSU herbarium maintains active exchange programs with herbaria worldwide. We can provide northeastern North American and southern South American specimens, as well as occasional material from other parts of the world. If you are interested in exchange of specimens, please contact the Director.
