Setaphyta

Setaphyta
A mosaic of liverworts and mosses
Scientific classification
Kingdom:	Plantae
Clade:	Embryophytes
Clade:	Setaphyta
Divisions
Marchantiophytina – liverworts Bryophytina – mosses

The Setaphyta are a clade within the division Bryophyta sensu lato which includes Marchantiophytina (liverworts) and Bryophytina (mosses). Excluded are the Anthocerotophytina (hornworts). ^{[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]

Phylogeny

There is strong phylogenetic evidence for Setaphyta. ^{[1] [4] [5]}

'Monophyletic bryophytes' model	'Liverworts plus mosses–basal' model
embryophytes vascular plants bryophytes hornworts setaphytes mosses liverworts	embryophytes vascular plants hornworts setaphytes mosses liverworts
Two of the most likely models for bryophyte evolution. [5]
