Onocleaceae is a small family previously included in Dryopteridaceae but now shown to be sister to Blechnaceae. It is largely confined to north temperate regions, with the greatest diversity in China. It is represented in New Zealand by a single naturalised species, Onoclea sensibilis, which has been collected once from Nelson.
The species is recognised by its long-creeping rhizomes and strongly dimorphic fronds. The sterile fronds are pinnatifid to pinnate-pinnatifid, with broad segments and reticulate veins, whereas the fertile fronds are much narrower than the sterile fronds, 2-pinnate, and with free veins. The fertile pinnae are linear, bearing very short, rounded, bead-like secondary pinnae, and sori tightly enclosed by the strongly inrolled margins.
