Setaphyta
A mosaic of liverworts and mosses
Scientific classification Edit this classification
Kingdom: Plantae
Clade: Embryophytes
Clade: Setaphyta
Divisions

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]

Phylogeny

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