Description: Terrestrial, lithophytic or epiphytic ferns; rhizomes short- to long-creeping or climbing, covered with scales.
Fronds commonly dimorphic; lamina simple to once-pinnate; scales often present; hairs uncommon, small and usually glandular; veins free, simple or forked, or anastomosing. Fertile fronds usually distinct with contracted lamina, or (in Nephrolepis) fertile fronds similar to vegetative fronds.
Sporangia usually naked, often nearly covering the entire undersurface of fertile fronds, or (Nephrolepis) the sori marginal. Spores bilaterally symmetrical, bean-shaped, monolete.
Distribution and occurrence: World: 4 or 5 genera (Nephrolepis is often not included in accounts of Lomariopsidaceae), mainly tropical regions (some species extending to temperate regions); Australia: 2 genera; c. 4 species.
