Description: Epiphytic or terrestrial ferns; rhizome long-creeping or tufted and stoloniferous, densely covered with peltate-based scales; stipes sometimes articulated to the rhizome.
Fronds uniform or somewhat dimorphic, vernation circinate; lamina simple, pinnate or more compound, herbaceous to leathery, glabrous or hairy; veins mostly free.
Sori mostly indusiate, marginal or superficial, ± circular; indusium peltate, reniform or cup-shaped and opening towards the margin.
Distribution and occurrence: World: c. 9 genera, c. 200 species, mainly tropical, extending to temperate regions. Australia: 4 genera, 15 species, all States except S.A.
A heterogeneous family. Nephrolepis has been moved to the family Lomariopsidaceae and is sometimes placed in its own family Nephrolepidaceae.
