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.

Endemic. New Zealand: Kermadec, Three Kings, North, South, and Chatham Islands. In the South Island known from the Marlborough sounds south to Hokitika and Banks Peninsula
Coastal to montane (but mostly found within coastal and lowland areas). Occupying a diverse range of habitats from coastal cliffs and rock stacks to deep forest where it may be an epiphyte or grow on the ground.
Wetland plant indicator status rating
Information derived from the revised national wetland plant list prepared to assist councils in delineating and monitoring wetlands (Clarkson et al., 2021 Manaaki Whenua – Landcare Research Contract Report LC3975 for Hawke’s Bay Regional Council). The national plant list categorises plants by the extent to which they are found in wetlands and not ‘drylands’. The indicator status ratings are OBL (obligate wetland), FACW (facultative wetland), FAC (facultative), FACU (facultative upland), and UPL (obligate upland).
UPL: Obligate Upland
Rarely is a hydrophyte, almost always in uplands (non-wetlands).
Rhizome stout, often forming a hard woody mass above ground, bearing pale brown, shiny, ovate, acuminate scales up to 30 × 7 mm. Stipes 80-200 mm long, dark brown, stout, densely covered in narrow scales with very long filiform apices. Laminae oblong to elliptic, 0.18-1.00 m long, 100-350 mm wide, dark green and glossy above, pinnate. Rachis brown below, green above, stout, slightly ridged, scaly. Pinnae 4-15 pairs, lanceolate to narrowly oblong or ovate, acuminate, crenate-serrate to ± entire, cuneate at base, 40-150 × 10-30 mm, frequently covered in very small hair-like scales on the underside. Sori up to 20 mm long, not reaching lamina edge.
Often confused with Asplenium obtusatum G.Forst. for which it is distinguished by the rachis and foliar scales which have very long hair-like apices, and by the pinnae which are firm (usually not thick and fleshy), glossy above, and acuminate to ± acute. Some forms of A. oblongifolium found on rock stacks along the west coast of the North Island (from about Kawhia south) would repay further investigation was these have distinctly dull, rather coriaceous, fleshy, fronds, and broader rachis and foliar scales, thus intergrading somewhat with A. obtusatum. These features are retained in cultivation.
Not applicable - spore producing

Minute spores are wind dispersed (Thorsen et al., 2009).
Easily grown though often rather slow to establish. An attractive and popular plant widely used for mass plantings in shaded sites. An excellent pot plant. Be vigilant for scale and mealy bug infestations which are a bane to the cultivation of all New Zealand asplenia.
asplenium: From the Greek a- ‘without’ and splene ‘spleen’, a northern hemisphere species, the black spleenwort (Asplenium adiantum-nigrum), was once believed to be a cure for diseases of the spleen.
oblongifolium: Oblong leaves
