The Friesner Herbarium of Butler University, Indianapolis, Indiana, 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. In the 1930s and 1940s, Butler had an active Masters degree program in Botany with a focus on florisitics and ecology of the state. The collection currently houses over 100,000 specimens. Label data have been digitized for the ca. 50,000 sheets collected in Indiana and work has begun on non-Indiana and foreign sheets. More information on the collection is available at www.butler.edu/herbarium. We welcome liberal use of our digitized collections. We request that BUT is appropriately cited, and that individual specimens are cited where appropriate, in any publication that includes our data, whether physical specimens are examined or not. Thank you!
