The Hortorium Herbarium regularly loans plant specimens to other herbaria and botanical museums for scientific research purposes. All loan requests should be directed to Kevin C. Nixon, Curator and emailed to firstname.lastname@example.org. Loans are granted for a period of one year. Should more time be necessary, requests for an extension should also be directed to Kevin Nixon. In addition, the Herbarium maintains an exchange program with various institutions as a means to add to its holdings. Gifts of plant specimens are also appreciated and can be directed to the Assistant Curator.
Since the merger of the Wiegand and Hortorium Herbaria in 1977, the collection has grown to ca. 860,000 specimens. Hortorium specimens are cited using the acronym BH. However, Wiegand material is still distinct, and may be cited as CU if necessary for historical reasons. Over the years, several rubber-stamped, printed, and impressed herbarium seals have been used in preparing botanical specimens for BH and for CU.
