Monocleaceae

Monoclea is a genus of two species, of liverworts. It may be regarded as a family, Monocleaceae (of two species) in order Marchantiales. Classifications of the late twentieth century recognized a separate order, Monocleales, but later molecular studies show that it is closely related to the liverwort genus . [more]

Pallaviciniaceae

Pallaviciniaceae is a widely-distributed family of liverworts in the order Metzgeriales. All species are thallose, typically organized as a thick central costa (midvein), each side with a broad wing of tissue one cell in thickness. All species are dioicous. The greatest diversity is in Australasia, with some species endemic to that region, though species belonging to the family may be found on every continent except Antarctica. [more]

Pelliaceae

Pelliaceae is a family of liverworts with only two genera: Pellia (in the temperate Northern Hemisphere) and Noteroclada (in the Southern Hemisphere). The two genera are easily distinguished, not only because they occur in completely separate regions of the world, but because Noteroclada has a leafy appearance, while Pellia is more clearly thallose. [more]

Personiellaceae

[more]

Perssoniellaceae

[more]

Phycolepidoziaceae

Phycolepidozia exigua is the only species of liverwort in the genus Phycolepidozia and family Phycolepidoziaceae. It is endemic to Dominica, where it is critically endangered. Its natural habitat is subtropical or tropical moist lowland forests. [more]

Phyllothalliaceae

Phyllothallia is a small genus of liverworts of the Southern Hemisphere. It is classified in order Metzgeriales and is the only member of the family Phyllothalliaceae within that order. Unlike most members of the Metzgeriales, Phyllothallia has a leafy appearance. The genus has a disjunct distribution, with the species found in New Zealand while the other species in the genus, Phyllothallia fuegiana, occurs in Tierra del Fuego. [more]

Plagiochilaceae

Plagiochilaceae is a family of liverworts in order Jungermanniales. There may be anywhere from 500 to 1300 species, most of them from the tropics, but the exact number is still under revision. The family also has a wide distribution in temperate and arctic areas. [more]

Pleuroziaceae

Pleurozia is the only genus of liverworts in the family Pleuroziaceae, which is classified within the order Jungermanniales. The genus includes eleven species, and as a whole is both physically distinctive and widely distributed. The lower leaf lobes of Pleurozia species are fused, forming a closed water sac covered by a movable lid similar in structure to those of the angiosperm genus Utricularia. These sacs were assumed to play a role in water storage, but a 2005 study on found that the sacs attract and trap ciliates, much in the same way as Utricularia. Observations of plants in situ also revealed a large number of trapped prey within the sacs, suggesting that the species in this genus obtain some benefit from a carnivorous habit. After Colura, this was the second report of zoophagy among the liverworts. [more]

Porellaceae

Porellaceae is a family of liverworts in order Jungermanniales. It includes two genera: , and Porella. [more]

Pseudolepicoleaceae

Pseudolepicoleaceae is a family of liverworts in order Jungermanniales. [more]

Ptilidiaceae

Ptilidium is a genus of liverwort, and is the only genus in family Ptilidiaceae. It includes only three species: Ptilidium californicum, , and Ptilidium pulcherrimum. The genus is distributed throughout the arctic and subarctic, with disjunct populations in New Zealand and Tierra del Fuego. Molecular analysis suggests that the genus has few close relatives and diverged from other leafy liverworts early in their evolution. [more]

Radulaceae

Radula is a genus of liverwort, and is the only genus in family Radulaceae. It contains the following species (but this list could be incomplete): [more]

Ricciaceae

Ricciaceae is a family of liverworts in order Marchantiales, with two genera. [more]

Riellaceae

Riella is the only genus in the liverwort family Riellaceae, and includes about eighteen species. Plants in the genus are small and grow submerged in shallow temporary pools. Although the genus is widely distributed in the Northern Hemisphere, locating populations is often difficult. Its occurrence is sporadic and local, and the tiny plants are ephemeral. The ornamented spores remain viable for several years, allowing the plants to survive annual drying of their habitat. The plants are easily grown in laboratory cultures. [more]

Scapaniaceae

Scapaniaceae is a family of liverworts in order Jungermanniales. The family has been extended to include the former family Lophoziaceae. [more]

Schistochilaceae

Schistochilaceae is a family of liverworts in order Jungermanniales. [more]

Sphaerocarpaceae

Sphaerocarpaceae is a family of liverworts known as bottle liverworts. Approximately ten species are included in this family, most of them in the genus Sphaerocarpos, but one additional species in the genus Geothallus. [more]

Takakiaceae

Takakia is a genus of two species of moss known from western North America and central and eastern Asia. The genus is placed as a separate family, order and class among the mosses. It has had a history of uncertain placement, but the discovery of sporophytes clearly of the moss-type firmly supports placement with the mosses. [more]

Targioniaceae

Targionia is a genus of liverworts in order Marchantiales. It is a member of family Targioniaceae within that order. This genus has worldwide distribution in areas with a Mediterranean climate. That is, in regions with hot dry summers and cool wet winters. [more]

Treubiaceae is a family of liverworts in the order Treubiales. Species are large and leafy, and were previously classified among the Metzgeriales. [more]

Trichocoleaceae

Trichocoleaceae is a family of liverworts in order Jungermanniales. [more]

Vandiemeniaceae

Vandiemenia ratkowskiana is the only species of liverwort in the genus Vandiemenia. It is endemic to Tasmania, Australia. Its natural habitat is subtropical or tropical dry forests. [more]

Verdoorniaceae

[more]

Vetaformaceae

Vetaforma is a genus of liverworts found only in Argentina and Chile, and contains a single species Vetaforma dusenii. It is classified in order Jungermanniales and is the only member of the family Vetaformataceae within that order. The genus and family names were originally published in 1960, but this publication was invalid under Article 36.1 of the ICBN. [more]
