Lindsaea linearis is known as the screw fern, as the fronds may have a twisting appearance. It has a creeping stem with fronds that can grow up to 50 cm (20 in) in length.[1] It is a small fern of widespread distribution in many parts of Australia, as well as New Zealand and New Caledonia.[2] Found in a variety of habitats, often near swamps or moist places and by rocks, heathland or open forest.[3] It has a dark stem, unlike the similar necklace fern, which is green.
The screw fern was first described by Swedish botanist Olof Swartz in 1801, and still bears its original name.[4] Two varieties are recognised, namely var. linearis and var. cuneata.[5]
