A total of 3463 collections of 73 species of ferns (47 species) and fern allies (26 species) was made between 1854 and 1983 by 164 collectors. This computer data base was used to generate a catalogue of all the collections, as well as maps based on a 10 square kilometer grid system using a universal transverse mercator projection. The historical collecting trends are discussed, particularly as they relate to distributions of various species.
