Summary

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. Multicellular purple colored scales with single cell thickness and unicellular rhizoids are present on the ventral surface of the thallus....read more on Wikipedia.
