The Setaphyta are a clade within the Bryophyta which includes Marchantiophytina (liverworts) and Bryophytina (mosses).

Anthocerotophytina (hornworts) are excluded.

[1][2] A 2018 study found through molecular sequencing that liverworts are more closely related to mosses than hornworts, with the implication that liverworts were not among the first species to colonize land.

[3] There is strong phylogenetic evidence for Setaphyta.
