Complex thalloid liverworts are non-vascular plants known for their distinctive liver-like appearance, earning them the common name of liverworts. These plants typically exhibit a flat, lobed thallus that hugs the ground, allowing them to absorb moisture and nutrients directly from their often moist and shaded environments. Their reproduction involves the production of spores, and they thrive in damp, forested areas, contributing to the ecosystem by forming dense, green carpets on forest floors and rocks.
