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. Many students and other Butler faculty have contributed plants through the years. The specimens, with their carefully documented labels, comprise a reference library on historical distribution, habitats, and timing of flower and fruit production.
