Hymenophyllum
Also called Filmy Ferns, Mauku
Hymenophyllum is a genus of tiny, translucent ferns named for their membranous, one-cell-thick fronds, and the common name filmy fern covers this and related thin-leaved ferns. Commonly grown members need constant high humidity and shade, since their fronds dry out very quickly.
Hymenophyllum is a genus of ferns in the family Hymenophyllaceae. Its name means "membranous 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 desiccation. 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.
