Marchantia is a genus of flat, ribbon-like liverworts (non-flowering plants) that spread across damp ground, rocks and stream banks. The key to growing it is constant moisture and bright, indirect light, since the most widely grown member, Marchantia polymorpha, is a common weedy species kept mainly for study.
Marchantia is a genus of liverworts in the family Marchantiaceae and the order Marchantiales. The genus was named by French botanist Jean Marchant after his father. The widespread species Marchantia polymorpha has had its genome sequenced and is an incipient model organism.
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.
