Pennsylvania State University Herbarium (PAC)

The Pennsylvania Agricultural College (PAC) Herbarium represents one of the oldest natural history collections at Penn State University. Established in 1859 with 3,000 specimens donated by Penn State’s first president Evan Pugh, the collection has since grown to over 100,000 items including mounted voucher specimens, seed vials and jars, and specimen jars which hold a portion of the algal collection.
