The embryophytes (/ ˈ ɛ m b r i ə ˌ f aɪ t s /) are a clade of plants, also known as Embryophyta (/ ˌ ɛ m b r i ˈ ɒ f ə t ə,-oʊ ˈ f aɪ t ə /) or land plants. They are the most familiar group of photoautotrophs that make up the vegetation on Earth 's dry lands and wetlands .
An example of moss (Bryophyta) on the forest floor in Broken Bow, Oklahoma. Bryophytes (/ ˈ b r aɪ. ə ˌ f aɪ t s /) [2] are a group of land plants (embryophytes), sometimes treated as a taxonomic division, that contains three groups of non-vascular land plants: the liverworts, hornworts, and mosses (Bryophyta sensu lato).

The euphyllophytes are a clade of plants within the tracheophytes (the vascular plants). The group may be treated as an unranked clade, [1] a division under the name Euphyllophyta [2] or a subdivision under the name Euphyllophytina. [3]
Hornworts are a group of non-vascular Embryophytes (land plants) constituting the division Anthocerotophyta (/ ˌ æ n θ oʊ ˌ s ɛ r ə ˈ t ɒ f ə t ə,-t ə ˈ f aɪ t ə /).The common name refers to the elongated horn-like structure, which is the sporophyte.
Archegoniatae was a higher taxonomic term that indicated those embryophytes having a female sexual organ in the form of an archegonium.The term was first introduced by the Russian botanist Ivan Nikolaevich Gorozhankin (1848–1904) in 1876 to indicate a division including bryophytes, pteridophytes and gymnosperms in contrast to the Gynoeciatae (Angiosperms) with a more complex female organ.
The clade includes all land plants (embryophytes) except for the bryophytes (liverworts, mosses and hornworts) whose sporophytes are normally unbranched, even if a few exceptional cases occur. [1] While the definition is independent of the presence of vascular tissue , all living polysporangiophytes also have vascular tissue, i.e., are vascular ...
Viridiplantae (lit. ' green plants '; kingdom Plantae sensu stricto) [6] is a clade of around 450,000–500,000 species of eukaryotic organisms, most of which obtain their energy by photosynthesis.
