Austin Peay State University Herbarium (APSC)

Established in 1942, the Austin Peay State University Herbarium (APSC) has roughly 120,000 specimens and is the second largest herbarium in the Kentucky/Tennessee region. In 2017, APSC nearly doubled from its previous size due to the acquisition of the former Western Kentucky University herbarium (WKU) and Davies Herbarium of Louisville (DHL). Although located in Clarksville Tennessee, the APSC collection is mostly Kentucky-based with significant collections from the Louisville, Bowling Green, and Land Between the Lakes areas. Under the curation of Dwayne Estes and the management of Mason Brock, APSC has become one of the fastest growing herbaria in the Southeast, with new specimens being accessioned on a daily basis. In addition to an active graduate student program, APSC is also the home of the Southeastern Grasslands Initiative (SGI) which places it at the forefront of taxonomy and conservation science.

Significant contributors: Edward Chester, Alfred Clebsch, William H. Ellis, Dwayne Estes, Robert Kral, and Max Medley

Information regarding specimens with protected localities will be promptly supplied to all legitimate researchers upon request. In order to uphold our conservation and education based values, and to advance the purpose of this herbarium digitization project, APSC has chosen not to censor any locality information for reasons other than extreme global rarity or potential economic exploitation.
