Common Liverwort

<em>Marchantia polymorpha</em>, the common liverwort, is a thalloid bryophyte in the family Marchantiaceae and one of the most cosmopolitan non-vascular plants on Earth. It is found across Asia, Europe, North America, and South America, typically colonizing moist, shaded habitats such as stream banks, damp soil, rock surfaces, and disturbed ground. The common liverwort reproduces both sexually, producing umbrella-shaped reproductive structures called gametangiophores, and asexually through small disc-shaped gemmae produced in cup-shaped gemma cups on the thallus surface. Its flat, ribbon-like thallus with a distinct midrib is a recognizable feature of this species. The species has not been formally evaluated by the IUCN due to its wide distribution and abundance. Marchantia polymorpha is a model organism in plant biology, widely used in laboratory research to understand plant evolution, development, and genetics. It is one of the earliest diverging lineages of land plants, providing valuable insights into the evolutionary transition from aquatic to terrestrial environments.
