The vascular flora of Chiapas, Mexico, has been the subject of a long term study by Dennis Breedlove of the California Academy of Sciences. This has stimulated a related project dealing with the bryophyte flora of the region. A collecting expedition in 1988 generated 1420 collections of bryophytes. Specialists from 13 institutions assisted with identifications. Approximately 70% of the collections have been determined. Checklists of species of bryophytes of Chiapas are presented. These lists are based on collections at CAS and literature citations. A total of 364 species of mosses and 310 species of hepatics and hornworts are reported from Chiapas.
The bryophyte collection at MEXU was formally established in 1973 with about 3000 specimens; at present, it contains nearly 35000. Emphasis has been made on Mexican and tropical American localities, but herbarium holdings also include temperate areas. Herbarium information is now being stored in a database to assist floristic and taxonomic research in progress and for further reference.
