Alexander N. Sennikov 2002: Bibliographic catalogue of Hieracium and Pilosella names published by Finnish authors. Norrlinia 9: 1-109. ISSN 0780-3214. ISBN 952-10-0530-0

A catalogue of Hieracium and Pilosella names was compiled on the basis of 90 literature sources mostly published by Finnish authors in Finnish journals and books. Each name was critically evaluated in light of the current International Code of Botanical Nomenclature and provided with full bibliographic citations. Approximately 100 validly published specific names are additions to the Index Kewensis, and many entries included there are here corrected.
