Bryophyta: liverworts, hornworts & mosses

• Under construction

For definitions and background see the article in Wikipedia. "There are three groups, the liverworts, hornworts, and mosses. Modern studies generally show that the liverworts were the first to diverge, followed by the hornworts, while the mosses are the closest living relatives of the vascular plants. Originally the three groups were brought together as the three classes of division Bryophyta. However, since the latter is a paraphyletic group, they now tend to be placed in three separate divisions."

The British Bryological Society (BBS) has information on a 1999 survey in the Craig Cerrig Gleisiad NNR.
