A recent survey of the liverworts of Mahogany Hammock, Everglades National Park, Florida, USA, complements the surveys in the 1950s, 1970s, and 1980s. Despite disturbances by hurricanes, changes in local ecology, and millions of park visitors, Mahogany Hammock still supports a rich hepatic flora with mostly tropical affinities. We collected 29 of ca. 47 taxa that have been recorded from the hammock, including six new records. Most taxa were found growing on the bark of trees and shrubs, but some were epiphyllous on the leaves of trees, ferns, and epiphytic Tillandsia (Bromeliaceae). The boardwalk in the hammock also served as a substrate for liverworts.
