Liverworts, mosses, and hornworts - technically referred to as
are considered to be a pivotal group in our understanding of the origin of land plants because they are believed to be among the earliest diverging lineages. Bryophytes are ecologically significant, contributing to nutrient cycles, forming a major component of forest canopy humus, and are effective rainfall interceptors that add to hill stability and help to prevent soil erosion. Many bryophytes also have chemical constituents that show important biological activities such as anti-micorbial, anti-fungal, and muscle relaxing activity.
The Field Museum holds approximately 250,000 unaccessioned and accessioned
At present, more than 45,000 searchable records are available. The majority of these records represent accessioned specimens from New Zealand, North America, and South America, including collections from J. J. Engel, M. Lewis, M. S. Taylor and R. M. Schuster. Records also include voucher specimens as part of the NSF-funded Assembling the Liverwort Tree of Life project (LiToL).
Databasing efforts of the bryophyte collection are ongoing, including the digitization of specimen labels and data entry of core fields (taxon, country, latitude/longitude, date collected, collector, and collection number). This effort is made possible with the support of the NSF Biological Research Collection Program (
Award No. 0749762).
The database is searchable by the various fields below, including taxon (at any taxonomic rank), distribution and ecology, or one can search specific localities or regions. Note that for many records, identification is to genus level only. All liverwort type specimens are databased. The moss types are in the process of being databased.
