A new survey of liverworts in three tropical hardwood hammocks in South Florida 100 years after they were first surveyed by John Kunkel Small found that the liverwort flora is mostly intact. The new survey collected 24 species, recollecting eight of the 13 species first collected by Small in these hammocks. Some taxa not noted by Small are xerophytic species that may have colonized the hammocks since Small's time. Epiphyllous species are a characteristic and noteworthy component of the hammock liverwort flora; eight taxa were found in this survey.
