Notholaena is a genus of ferns in the family Pteridaceae found exclusively in the New World. Ferns of this genus are mostly epipetric (growing on rock) or occurring in coarse, gravelly soils, and are most abundant and diverse in the mountain ranges of warm arid or semiarid regions. They typically have a creeping or erect rhizome and leaves that are pinnatifid to pinnate-pinnatifid with marginal sori protected by a false indusium formed from the reflexed margin of the leaf. Members of Notholaena also have a coating of whitish or yellowish farina (a powdery wax that prevents desiccation) on the surfaces of the leaves. The farina is often limited to the abaxial (lower) leaf surface, but may occur on the adaxial (upper) leaf surface as well.


Read about Notholaena in the Standard Cyclopedia of Horticulture 

Notholaena (Latin, spurious, cloak; from the rudimentary indusium). Polypodiaceae. Often written Nothochleana, but the above is Robert Brown's original orthography. A group of mostly warm temperate rock- loving ferns, differing from Cheilanthes mainly in having no marginal indusium. Some of the species are coated with a golden or silvery wax-like powder. Culture as in Cheilanthes.
