Bryophyte Classification

The roughly 18,000 species of bryophytes are generally classified into three coordinate phyla, the Marchantiophyta (liverworts), Bryophyta (mosses) and Anthocerotophyta (hornworts). Phylogenetic analyses such as those of Mishler et al. (1994) and Qiu et al. (2006) suggest that these phyla do not form a monphyletic group, but rather represent a grade in embryophyte evolution. In most recent analyses liverworts are resolved as the first divergence of land plants (embryophytes).
