Bryology and Lichenology Zona, Scott [1], Sadle, Jimi [2]. Liverworts (Marchantiophyta) of Mahogany Hammock, Everglades National Park, Florida. Everglades National Park (ENP) is known for its unique mixture of temperate and tropical vascular plant species. However, little published information on non-vascular plants within ENP ENP is available. Surveys for liverworts at a discreet site in central ENP (Mahogany Hammock) were carried out in 1955 and provide a valuable reference point for assessing potential changes that may have occurred in the liverwort flora. Changing climate, intense tropical cyclones and park management actions including installation of a boardwalk and exotic plant control have all affected Mahogany Hammock over the past 60 years. In this study, we collected 27 taxa, from Aneuraceae, Cephaloziaceae, Jubulaceae, Lejeuneaceae, Lepidoziaceae, Plagiochilaceae, and Radulaceae. The hepatic flora shows strong tropical affinities. One of the most remarkable finds is a species of Telaranea (Lepidoziaceae). Only one species, T. nematodes, is known from the eastern USA (including Mahogany Hammock), but our species is not that; on-going taxonomic studies will determine the identity of this taxon. Despite the presence of the boardwalk in the hammock and damage from two major hurricanes (Donna in 1960, Andrew in 1992), Mahogany Hammock still supports a rich hepatic flora that is very similar to that found in the 1955 survey. We found no evidence for invasion of xerophytic species, as was found for tropical hardwood hammocks near the coasts. We documented the presence of epiphyllous species at this location.
