Riccardia multifida is a species of liverwort belonging to the family Aneuraceae.
It has cosmopolitan distribution, and is widely found on both coasts of North America, Europe, and east Asia.
A novel group of phytochemicals isolated from R. multifida in 1983, dubbed Riccardins have demonstrated significant preclinical anticancer potential against immortalized human osteosarcoma cell lines.
