The Marchantiopsida are one of the classes of liverworts from the kingdom of plants . The class includes around 400 species.


The class has few features in common. These are the thallous organization, a single-layer sporangia wall , and special oil bodies in chlorophyll-free cells. The rest of the structure is quite different in the individual subclasses.

The species of Marchantiidae have a complex thallus . Most species have air chambers inside the thallus and breathing pores. In their tissue there are oil bodies made of terpenes , which give them a typical scent. The Sphaerocarpidae have a partly lobed, partly winged thallus, and the Monocleidae have a very simple thallus organization. The term "complex liverworts", which is often used for the whole class, therefore only applies to the Marchantiidae.

The diploid sporophyte in Marchantiopsida is covered for a very long time by the wall of the archegonium and only appears shortly before the maturity of the meio spores . These are then pressed out of the spore chamber with the help of elaters .


The Marchantiopsida comprise 19 families, 32 genera and around 380 species in two subclasses:
