The Collegium Palynologicum Scandinavicum (CPS) is a society of palynologists in the Scandinavian countries. CPS was established in 1969 by Professor Gunnar Erdtman and a group of Nordic palynologists with the aim to stimulate the interest for palynology and to coordinate palynological research in the Nordic countries.

The association was also to ensure the continuity and edition of the journal Grana Palynologica (now GRANA) and the World Pollen and Spore Flora (WPSF).

Please browse the menu to the left and find out who we are, what we do, how you might join, contribute, profit and learn to know people in the wide and interesting field of Nordic palynology. Hear of you if you have any interest, inquires, ideas, etc.: Contact.


GRANA is an international journal of palynology and aerobiology published under the auspices of the Collegium Palynologicum Scandinavicum (CPS) in affiliation with the International Association for Aerobiology (IAA).

GRANA articles appear online prior to the printed issue once they are in publication format. Click the 'latest articles' tab on GRANA's website at T&F.
