NVS code
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 conservation 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). 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.

Distribution
Indigenous. New Zealand: Kermadec (Raoul Island), Three Kings, North, South and Chatham Islands. Also Australia, Borneo, New Guinea, Vanuatu, Fiji, Samoa, Tahiti and Norfolk Island (the type locality). Common in the North Island but scarce over much of the South Island part of its range.
Habitat
Coastal to montane but most common in lowland closed forest. Usually found growing along streams sides in deeply shaded sites on rocks, overhangs and in crevices. Because of this habitat preference it is very easily overlooked.
Features
Terrestrial (rarely epiphytic) fern forming dense carpets on suitable substrates. Rhizomes c.0.1 mm diameter, long-creeping; hairs dense short, red-brown. Fronds 13-40(-100) mm long, dark green. Stipes widely spaced, 3-13(-25) mm long, winged almost to the base. Rachises winged. Lamina 11-40(-80) × 5-15(-25) m, narrowly ovate to linear, deeply 2-3-pinnatifid. Ultimate segments 0.5-0.7 mm wide; margins entire; marginal cells clear, elongate, with oblique end walls;apices obtuse, often notched; false veins absent. Sori immersed in short, basal acroscopic segments of the pinnae; involucre funnelform, 1.5-2.0 × 1.0-1.5 mm wide, winged; mouth dilated, entire; receptacle exserted up to 4 mm beyond mouth.
Similar taxa
Of the New Zealand species Trichomanes endlicherianum is most likely to be confused with T. colensoi which is a much less common plant of montane forested habitats. Trcihomanes colensoi differs from T. endlicherianum by its more widely spaced pinnae, the lack of a wing on the stipes or rachises, finely divided fronds and stalked (pedunuculate) indusia. From Trichomanes endlicherianum the New Zealand form of T. caudatum differs by its deltoid frond and by the lobed involucre of the fruiting receptacle and by its epiphytic habit. Trichomanes venosum is easily distinguished from both these species by its conspicuously veined pinnae.

Taxonomic Notes
Previously NZPCN had followed Ebihara et al. (2006) in recognising Abrodictyum as distinct from Trichomanes - recently Brownsey & Perrie (2016) have rejected this idea favouring a return to the past broad circumscription of Trichomanes used in New Zealand.
