摘要：

Complete sequences for the 18S-rRNA gene of 22 bryophytes (12 completely new) were determined and used to construct phylogenetic trees. The evaluation of sequence data according to the maximum parsimony principle (PAUP 3.1.1) and the neighbor-joining method (MEGA) results in similar phylogenetic trees in which the Bryopsida appear as a sister group to the Jungermanniopsida, and both together as a sister group to the Marchantiopsida. Among the Marchantiopsida, the Sphaerocarpales diverge early as a separate clade. The Metzgeriales and Jungermanniales are monophyletic. They belong to one clade and cannot be separated by either method of evaluation.
