Miami University is the home of Ohio's largest herbarium, the Willard Sherman Turrell Herbarium. The herbarium's holdings of approximately 620,000 specimens are worldwide in both geographical and taxonomic coverage. The collection consists of 330,000 vascular plant specimens, as well as 140,000 bryophytes, 100,000 fungi, 35,000 lichens, 10,000 algae, and 5,000 fossil plants. There are several thousand type specimens contained in the collection, as well as many sets of cryptogamic exsiccatae. Active exchange programs are ongoing with many herbaria worldwide to ensure the continued breadth and depth of the collection. The W.S. Turrell Herbarium Fund is an endowment which benefits the herbarium, and is restricted to support of the research activities of the staff and students in systematic botany.
