N2  - An account of the bryological activities on the Azores is given. Three phases can be distinguished: one at the end of the 19. century, when first collections of non-bryologists were made, which resulted in the discovery of less than one third of the presently known species and the description of many so called endemics. A second phase in the thirties of the 20. century is characterized by an intensive collecting activity of some bryologists, which enormously raised the species numbers. In a third phase at the end of the 20. century, tourism as well as activities of local bryologists raised again the species numbers. Revisions of genera reduced the number of endemic species and revisions of herbarium specimens of doubtful records even reduced the species numbers of hepatics.
