Discovery and collecting of the rare fern Diplazium sibiricum in Norway.

The first collection of Diplazium sibiricum from Norway was made in Sel in Gudbrandsdal in 1822 by P.F. Wahlberg. However, this collection was not correctly identified until after S.C. Sommerfelt had recognized his own collection from Kringen in Sel, made in 1831, as belonging to a new species: Aspidium crenatum Smf. (Aspidium kringelianum Smf. in schaedae, UPS). Indirect evidence indicate that S.C. Sommerfelt discovered the second of the three classical localities, Ørsanden in Ringebu, in 1836. The third classical locality was found by N.G. Moe and J. M. Norman in Kvam in Nord-Fron in 1849. Tables show subsequent collectors at each of the three classical localities, with date of visit, as well as all known localities in Norway. Solutions are suggested for a number of problems associated with insufficient/contradictory information and misleading labelling of specimens. The great activity of Swedish botanists in Gudbrandsdal during the time of the Swedish-Norwegian Union is documented. Collections in Swedish herbaria may contribute significantly to the solution of problems concerning the history of plant discovery in Norway. Norwegian botanists at the time were in close contact with Swedish colleagues.
