Hours of Operation


The herbarium is open by appointment.


The Friesner Herbarium curates ca. 100,000 specimens, about half collected in Indiana.

Area of Taxonomic and Geographic Concentration

The Herbarium focuses on plants of Indiana, currently accessioning specimens that document new significant records or voucher field inventories. Most of our legacy specimens were collected during the 1920s, '30s and '40s when Butler had an active Botany Master’s Degree program focused on floristics and "phytosociology." There was also an active exchange program operating in those years that build our holdings of plants collected outside the state.

Important Collections

Ray Friesner, Charles Deam, John Potzger, Charles Ek, Helene Starcs, Paul Rothrock, Scott McCoy


The Herbarium is open by special arrangement to anyone. Specimens are available on loan to recognized botanical institutions engaged in taxonomic research.
