Welcome to The Kriebel Herbarium (PUL)

Kriebel Logo

The vascular plant collection at Purdue University is the oldest in the state of Indiana and has been in existence since the very inception of the University. Though established in 1869, only six professors had been hired to teach at Purdue University as of 1874, with one of these being botanist Rev. John Hussey (1831–1888). Hussey brought his personal plant collection as a teaching aid for his students, and some of his specimens are still in the Kriebel Herbarium (PUL) to this day. The modern PUL is the consolidation of three historical herbaria, those being the original started by Hussey (also known as the Stanley Coulter Herbarium), the vascular plant collections of Joseph C. Arthur, and the private herbarium of Ralph M. Kriebel (1897–1946), which was the largest, in excess of 10,000 specimens of Indiana flora, when the PUL was dedicated to Kriebel in 1961. Learn more about the history of the PUL here. This consolidated collection, now managed by the Department of Botany and Plant Pathology, comprises approximately 90,000 specimens, including vascular plants, algae, bryophytes and fungi.​​​​
