The Friesner Hearbarium is a systematic collection of nearly 100,000 dried, pressed, and preserved plant specimens. The Herbarium, third largest in the state, grew from the personal collection of Dr. Ray C. Friesner, Professor and Chair of the Butler University Botany Department, 1920-1952. The specimens, with their carefully documentated labels, comprise a reference library on historical distribution, habitats, and timing of flowering and fruit production. The collection's voucher specimens serve to verify plant identification.

Although the Herbarium contains plants from around the world, the collection emphasizes plants of the Ohio River Valley region. The collection is of great value to professional botanists; information can be shared through a network of exchange and loan of specimens. Students, faculty, and staff from Butler's Department of Biological Sciences frequently use the Herbarium as a reference. In addition, the Herbarium holdings are available to enrich teaching and laboratory exercises for students in biology courses.

The Herbarium is open to the public by appointment.  Call (317) 940-9413  or e-mail Dr. Rebecca Dolan, Director to arrange a visit.
