Accession Numbers and Herbarium Codes

Each herbarium specimen entered into an institution's collection is assigned a unique number, called the accession number. To differentiate between collections from each institution, accession numbers in this database include the acronym (abbreviation) of the herbarium. Larger herbaria have official acronyms, but the smaller collections, designate by an asterisk in the table below, do not have officially acronyms, so we have assigned each institution a code, shown in the table below.
