The Marchantiophyta 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.
Metzgeriales is an order of liverworts. The group is sometimes called the simple thalloid liverworts: "thalloid" because the members lack structures resembling stems or leaves, and "simple" because their tissues are thin and relatively undifferentiated. All species in the order have a small gametophyte stage and a smaller, relatively short-lived, spore-bearing stage. Although these plants are almost entirely restricted to regions with high humidity or readily available moisture, the group as a whole is widely distributed, and occurs on every continent except Antarctica.
Jungermanniaceae is the namesake family of leafy liverworts. It is a group of small plants that are widely distributed. Several genera formerly included within the family are now classified in the Myliaceae or Solenostomataceae.
Jungermanniopsida is the largest of three classes within the division Marchantiophyta (liverworts).
Aneuraceae is a family of thallose liverworts in the order Metzgeriales. Most species are very small with narrow, branching thalli.
Biantheridion is a genus of liverwort in the family Anastrophyllaceae. Its only accepted species is Biantheridion undulifolium the marsh flapwort, or marsh earwort. It is found in Austria, China, the Czech Republic, Denmark, Finland, France, Germany, Greenland, North Korea, Norway, Poland, Russia, Sweden, Switzerland, and the United Kingdom. Its natural habitat is swamps. It is threatened by habitat loss.
Jamesoniella is a formerly accepted genus of liverworts. It is considered to be included in the genus Syzygiella, but one species, Jamesoniella convoluta, has not be transferred to that genus nor synonymized.
Schistochila vitreocincta is a species of liverwort in the family Schistochilaceae. Under its synonym Perssoniella vitreocincta it was the only species in the monotypic genus Perssoniella and family Perssoniellaceae. It is endemic to New Caledonia. Its natural habitat is subtropical or tropical dry forests.
Lejeunea drehwaldii, synonym Sphaerolejeunea umbilicata, is a species of liverworts in the family Lejeuneaceae. It is endemic to Colombia. Its natural habitat is subtropical or tropical moist lowland forests.
Herbertaceae is a family of liverworts. The family consists of the genera Herbertus, Schisma and Triandrophyllum. The genus HerpocladiumMitten, 1873 was later merged into the genus Herbertus.
Cryptothallus is a previously recognized genus of liverworts in the family Aneuraceae. The plants are small, and are white to pale green as a result of lacking chlorophyll. This feature led to the creation of a separate genus. The morphology of species assigned to Cryptothallus is very similar to that of Aneura. As a result, Karen Renzaglia in 1982 suggested that the only species then placed in the genus, Cryptothallus mirabilis, may be considered "merely as an achlorophyllous species of Aneura." Wickett and Goffinet argued the same position on the basis of sequences of nuclear, mitochondrial, and plastid DNA, and moved Cryptothallus mirabilis to Aneura. A 2010 molecular phylogenetic study confirmed the position of Cryptothallus within Aneura. This was accepted in the 2016 world checklist of hornworts and liverworts.
Solenostomataceae is a family of liverworts in the order Jungermanniales.
Acrobolbus epiphytus is a liverwort species in the genus Acrobolbus. It occurs in New Zealand.
Gymnomitriaceae is a liverwort family in the order Jungermanniales.
Calypogeiaceae is a family of liverworts. This type of plant is a calcifuge.
Anastrophyllaceae is a family of liverworts belonging to the order Jungermanniales.
Balantiopsidaceae is a family of liverworts belonging to the order Jungermanniales.
Cephaloziellaceae is a family of liverworts belonging to the order Jungermanniales.
Cleveaceae is a family of liverworts belonging to the order Marchantiales.
Kymatocalyx, synonym Stenorrhipis, is a genus of liverworts in the family Cephaloziellaceae. The genus was first described by Theodore Herzog in 1950. Four species are accepted:
