The U.S. National Science Foundation and iDigBio are required to collect information on use of digitized collections-based specimen data. Please help us meet this requirement every time you use this search portal. Sustainability of the national digitization effort depends on evidence of data use! Maybe later.

Ada Hayden Herbarium (Iowa State University)

Specimen Records: 50,096
Media Records: 23,777
iDigBio Last Ingested Date: 2017-06-28

The <b>Ada Hayden Herbarium</b> has the largest collection of Iowa plants and fungi, containing over 600,000 specimens of vascular plants, bryophytes, fungi, and lichens. Functioning primarily as a research facility important for taxonomic studies (occurrence, distribution, and relationships of plants), it is also used for identifying unknown plants. Specimens are loaned to specialists at other institutions around the world to support research. Loans from other institutions allow our researchers access to other herbaria. Recently, herbaria have become a source of materials to use in molecular studies and to support basic research on biodiversity.
