Current conservation status
The threat classification status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Indigenous. In New Zealand known from Northland to Southland - easterly in its distribution.
Also known from Australia, South America, Africa, India and Europe.
Clay banks, alluvial banks, rock faces and overhangs. Often associated with liverworts.

Fronds 10-60 mm long, ovate or narrowly ovate, 2-3-pinnate, 8-50 x 7-30 mm, pale green or yellow-green, somewhat membraneous and delicate, glabrous.

Difficult and should not be removed from the wild.
This species is mainly threatened through habitat loss by competition with weeds, and by the removal of surrounding vegetation.
