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. 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.
Water:
Notholaena thrives in arid conditions with excellent drought tolerance, requiring minimal hydration. It prefers weekly watering to sustain its foliage and is commonly grown indoors, where its water retention capabilities suit controlled environments and consistent soil moisture levels.
Propagation:
Notholaena can be propagated through spores or division. Successful propagation requires high humidity, indirect bright light, and well-draining sterile soil. For spores, sow on moist medium and cover; for division, separate rhizomes and plant in similar soil. Maintain moisture and humidity for establishment.
