Pallaviciniaceae is a widely distributed family of liverworts in the order Metzgeriales. All species are thallose, typically organized as a thick central costa (midvein), each side with a broad wing of tissue one cell in thickness. All species are dioicous. The greatest diversity is in Australasia, with some species endemic to that region, though species belonging to the family may be found on every continent except Antarctica.^[1]
