Synopsis of relationships of the major groups of land plants, with more detail in the flowering plants [3,5]. Bryophytes have water-conducting tissues, although they are not the same as in other land plants, and hence we have put 'vascular' plants in quotes. Nodes with more than two branchesindicate groups for which inter-relationships are not yet clear.
