Northern Illinois University Herbarium

Specimen Records: 5,455

iDigBio Last Ingested Date: 2020-11-06

he herbarium at NIU is an internationally recognized systematic collection, initiated in the 1960s and enlarged significantly during the 1970s to the present. Holdings presently total about 19,000 specimens of vascular plants plus an additional 8000 bryophytes. A very large portion of the bryophytes (about 6000 specimens) is on permanent loan to MO (Missouri Botanic Garden).<hr> Special collections include a definitive collection of the genus Dahlia, which contains holotypes and isotypes plus a thoroughly documented array of hybrids between authenticated wild species. A second important collection is of Arbutus that also includes type material. The troublesome genus Agrimonia is more completely documented at DEK than at any other herbarium in the world. DEK presently maintains exchange relationships with more than 26 domestic and 6 foreign herbaria. As a consequence, coverage, while emphasizing the flora of Illinois, is worldwide.
