Bryophyta of Guam and Northern Micronesia. Characteristics of liverworts Like all bryophytes, the gametophyte is the dominant, free-living generation and the sporophyte is small and dependent on the gametophyte.
Hepatophyta gametophytes are either thallose or leafy.
Leafy liverworts are always flattened but so are some mosses. On Guam there are some on the rocks along the edge of the pool at Tarzan Falls .
