Petalophyllaceae Explained

Petalophyllaceae is a family of liverworts in the order Fossombroniales. Most species are thallose; that is, the plant is not differentiated into root, stem, and leaf. The thallus is typically small and bears lamellae on its dorsal surface that give it a ruffled, leafy appearance.[1] [2]

The family includes two extant genera, Petalophyllum and Sewardiella.
