Lomariopsidaceae Alston, Taxon 5(2): 25. 1956.

Type.

Lomariopsis Fée, Mém. Foug., 2. Hist. Acrostich.: 10. 1845.

Description.

Habit erect, creeping, or climbing; rhizomes dictyostelic, the ventral meristele elongate in transverse section or not; scaly at least when young; scales non-clathrate, basally attached or shallowly peltate, margins entire, toothed, or ciliate; fronds monomorphic or dimorphic; petioles with multiple vascular bundles arranged in a U-shape; laminae simple, pinnate, or pinnate-pinnatifid, provided distally with proliferous buds or not; pinnae articulate to the rachis or not; veins free, ± parallel or pinnate; sori acrostichoid or discrete and then round, with peltate indusia or exindusiate; spores brown, olive or green, chlorophyllous or not, bilateral, monolete, perine loosely attached, variously winged or ornamented.

Five genera and an estimated 70 species. Thysanosoria is included based on its morphological similarity to Lomariopsis ( Holttum and Hennipman 1959), but it has not been, to the present, subject to molecular phylogenetic analysis.
