The work with this database started in the winter of 1995. The type database is updated regularly as new types are continuously being identified in the collections. Identified types from the General herbarium have all been included, but the many South American type collections are still to be added and this work is not yet completed.

Description of fields used in the database:

  • Field 1. Name of the plant and its author. This field can have more than one name if the specimen typifies several. Hybrid species names are given as e. g. Carex x subpaleacea.
  • Field 2. Herbarium number. A unique identification number has been given each type. South American material have numbers beginning with an "R", whereas material from other parts of the world have numbers beginning with a "G". Number R-5000 is thus Poa pilcomayensis Hack. from Paraguay, and G-5000 is Porophyllum tharpianum Steyermark from Mexico.
  • Field 3. Family and Family number. The numbering system is according to Dalla Torre & Harms (Genera Siphonogamarum, 1905). In a few cases more than one family name is given, e. g. when a plant has been described as belonging to one family and later found to belong elsewhere, e. g. Urena ricinocarpa/Sparrmannia ricinocarpa Malvaceae (Tiliaceae).
  • Field 4. Collector and number. Name of the collector and the field number.
  • Field 5. Locality. The locality is normally given as it appear on the label. In some cases information has been added but then within brackets, e. g. "[Sweden]".
  • Field 6. Date. The date of collecting.
  • Field 7. Specification of type. This field gives an indication of what kind of type the material represents, holotype, lectotype, etc. Terms like cotype, or type are also used.
  • Field 8. Herbarium. This field indicates the location of the type specimen. Types from South America are kept separate from the types from all other areas, and so are the Linnaean types.
  • Field 9. Other information. This field contains various information, e. g.:
    - if material is preserved in alcohol. A separate database is available for the botanical collections in alcohol.
    - if the material is from the Nordic Flora area, i. e. Sweden, Norway, Denmark, Finland, Iceland, Spitsbergen, Jan Mayen or any of the other Norwegian Arctic Islands.
    - if there are more than one sheet of the same collection.
    - if there are photographs, negative numbers, pollen slides etc.
