The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

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.

Wetland plant indicator status rating
FACU: Facultative Upland
Occasionally is a hydrophyte but usually occurs in uplands (non-wetlands).
Terrestrial ferns. Rhizome long-creeping, much branched, stiff and somewhat brittle, 1–2 mm diameter, chesnut-brown, densely clad in slender red-brown, bristly hairs. Stipes 50–400 × 1–2 mm, stiff, muricate to almost smooth, densely clade in slender, bristly, red-brown hairs (especially near base) and short, glandular, yellow hairs in upper portion. Rhachis strongly to slightly zig-zagged, strongly muricate to smooth. Laminae 2–3–4-pinnate, 100–800 × 50–350 mm, deltoid to ovate or elliptic, stiffly coriaceous to subcoriaceous, adaxially yellow-green to yellow, abaxially, covered by numerous, short, glandular hairs, midirbs bearing bristly red-brown hairs; veins obscure, free. Pinnae finely dissected, primary pinnae shortly stalked, 70–200 × 30–50 mm, ovate to lanceolate, acuminate. Secondary pinnae shortly stalked, up to 25 × 10 mm, lanceolate. Segments decurrent, pinnatisect to almost pinnate, up to 5 × 2 mm, narrow, sharply toothed or incised, often apiculate. Sori usually copious, extending along both margins of segments, but not reaching base or apex. True indusium delicate, often vestigial
Easily distinguished by the yellow-green to yellow, glandular sticky, finely dissected, fragrant fronds, zig-zagged rachises and elongated marginal sori, protected by an inrolled, scarious lamina on the outside of the ultimate segments and a membranous (sometimes almost vestigial) indusium on the inside of the ultimate segments.

A weedy fern that often self establishes in gardens. Prefers a sunny, open situation and is tolerant of a range of soil types.
