Iowa State University, Ada Hayden Herbarium (ISC)

The Ada Hayden Herbarium’s bryophyte collection combines the “traditional” ISC holdings and those from the University of Iowa (formerly IA). The University of Iowa Herbarium was transferred to ISC in 2004. This collection contains significant numbers of specimens collected by bryologists and botanists associated with both universities: Elizabeth (Betty) Blagg, James T. Colbert, Henry S. Conard, Donald R. Farrar, Ada Hayden, Diana G. Horton, Robert L. Hulbary, Bohumil Shimek and others. Conard’s “Moss Clinics” added specimens from many additional bryologists worldwide. The bryophyte collection contains an estimated 45,000 specimens.
