Medium-creeping, wiry rhizome, in rock crevices, often in rainforest but extending to drier sites. Large-leaved Sickle Fern is found in northern New South Wales, Queensland and Lord Howe Island. Fronds are usually curved, 4 to 9 cm long, and 1 to 4 cm wide. Leathery to touch and a dull green. Juvenile fronds may be heart shaped. The stalks are around 1 to 5 mm long. Sori appear in a band, usually 2 to 3 mm wide, at the edge of the underside of the fronds.
