Fossombroniaceae is a family of liverworts, small, non-vascular plants that thrive in moist, shaded environments. These plants are distinctively recognized by their flattened, green, leaf-like structures arranged closely along the stem. This design aids in maximizing moisture absorption essential for survival in their typical damp habitats. Fossombroniaceae's unique morphology allows it to efficiently capture and store water, enabling it to inhabit various terrestrial ecosystems.
