Bryophytes - Mosses

Bryophytes are all embryophytes ('land plants') that are non-vascular: they have tissues and enclosed reproductive systems, but they lack vascular tissue that circulates liquids. They neither have flowers nor produce seeds, reproducing via spores. The term bryophyte comes from Greek βρύον - bryon, "tree-moss, oyster-green" + φυτόν - fyton "plant".

Bryophyte classification: Mosses are one group of bryophytes. Traditionally, all land plants without vascular tissues were classified together into a single taxonomic group, often a phylum. More recently, phylogenetic research shows that the bryophytes do not form a monophyletic group, but consist of three separate groups, the Marchantiophyta (liverworts), Anthocerotophyta (hornworts), and Bryophyta (mosses).
The term "bryophyte" then refers to a shared structure and way of life rather than a group with a single evolutionary origin. There is still some uncertainty over the exact evolutionary relationships among the liverworts, mosses, hornworts and vascular plants, in particular over the placement of the hornworts.
One analysis suggests that the hornworts are sister to the vascular plants.
