The Marchantiophyta (/ m ɑːr ˌ k æ n t i ˈ ɒ f ə t ə,-oʊ ˈ f aɪ t ə / ⓘ) are a division of non-vascular land plants commonly referred to as hepatics or liverworts.Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information.
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.
In botany, "seta" refers to the stalk supporting the capsule of a moss or liverwort (both closely related in a clade called "Setaphyta"), and supplying it with nutrients. The seta is part of the sporophyte and has a short foot embedded in the gametophyte on which it is parasitic.
Riccia is a genus of liverworts in the order Marchantiales. [1] ... It consist of only a capsule, missing both foot and seta, and does not perform photosynthesis. [7]
Marchantia polymorpha is a species of large thalloid liverwort in the class Marchantiopsida. [1] M. polymorpha is highly variable in appearance and contains several subspecies . [ 2 ] This species is dioicous , having separate male and female plants. [ 2 ]
Marchantia, an example of a liverwort (Marchantiophyta) An example of moss (Bryophyta) on the forest floor in Broken Bow, Oklahoma. Bryophytes (/ ˈ b r aɪ. ə ˌ f aɪ t s /) [1] 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.

Two rows of lobes extend laterally outwards from this axis, and there are small upright lobules at the base of each. The entire liverwort is around 1.5 cm wide and 4–9 cm long. There are mucus-covered hairs around the rhizoids and sex organs. [1] The sporophyte rises from around the apex of the lobe, and has a very large seta and relatively ...
