The Ohio State University Herbarium (OS) is a major collection of plant and fungal specimens and is a unit of the Department of Evolution, Ecology and Organismal Biology. We are part of OSU's Museum of Biological Diversity. Since its founding in 1891, the collection has grown to approximately half a million specimens and has worldwide coverage, with strengths in flora of the northeastern United States (especially Ohio) and in temperate South America. The Herbarium supports research and teaching at OSU and receives frequent use by researchers from other academic institutions, as well as by staff from governmental agencies such as the Ohio Department of Natural Resources.
