Marchantia is a genus of liverworts in the family Marchantiaceae and the order Marchantiales.
The thallus of Marchantia shows differentiation into two layers: an upper photosynthetic layer with a well-defined upper epidermis with pores and a lower storage layer. The thallus features tiny cup-like structures called gemma cups, containing gemmae, small packets of tissue that are used for asexual reproduction. The combination of barrel-shaped pores and the circular shape of the gemma cups are diagnostic of the genus.[1]: 22
Multicellular purple colored scales with single cell thickness and unicellular rhizoids are present on the ventral surface of the thallus.
