Tom S. and Miwako K. Cooperrider Herbarium serves to document the changing flora of the region, provides a repository for vouchers to document the identity of taxa on which studies are based, provides a references collection for identifications for the KSU community and beyond, and serves as a research facility through which specimen loans from collections from around the world may be arranged, housed, and studied.

Dr. Tom S. Cooperrider is Curator Emeritus. The collection is open by appointment.
The Tom S. and Miwako K. Cooperrider Herbarium was founded in 1921, and currently holds approximately 55,000 accessions. The strength of the collection is primarily in flora of northeastern Ohio, but we also have a good representation of other parts of the state and of other regions of North America. Significant collections include those of T. S. Cooperrider and his students, and late 19th and early 20th century collections of Almon Rood and his contemporaries. The collection is currently being database and will in the future be accessible online. In addition to vascular plants, we also have a growing collection of bryophytes, with the historical collections of Almon Rood as its nucleus.
Loans are made to recognized herbaria and are for a standard term of 1 year. Please contact the curator about arranging loans.
In addition to support from the university, the collection receives funding from individual contributors, notable among them being J. Arthur Herrick, Tom and Mix Cooperrider, Barbara Andreas, and David Jarzen. The collections are currently being databased; the bryophyte collection is now available online.
