Hymenophyllum is a genus of ferns in family Hymenophyllaceae. Its name means "membraneous leaf," referring to the very thin translucent tissue of the fronds, which gives rise to the common name Filmy Fern for this and other thin-leaved ferns. The leaves are generally only one cell thick and lack stomata, making them vulnerable to dessication. Consequently, they are found only in very humid areas, such as in moist forests and among sheltered rocks. They are small and easy to overlook.
