Welcome to the Friesner Herbarium

Exploring and documenting Indiana’s flora...

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