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: North, South and Chatham Islands. Also South America (Chile, Argentina)
Habitat
Montane to alpine. On sheltered rock outcrops and cliff faces in closed forest, subalpine scrub, on talus slopes or in tussock grassland and herbfield
Features
Rupestral (rarely terrestrial) fern. Rhizome long-creeping, rarely short-creeping, sometimes mat-forming, especially when dwarfed; paleae ovate-lanceolate, acute or apiculate, 1.5-3.0 × 4.5-0.75 mm. Stipes marked, (1-)5-20 mm long; stipe hairs usually dark red-brown, rarely paler, abundant, 0.5-3.0 mm long. Lamina (6-)20-70(-130) × (2.0-)2.8-5(-10) mm, linear oblanceolate to linear-spathulate, acute to obtuse; lamina hairs dark red-brown, rarely paler, 0.5-3.0 mm long, absent to common on lamina apart from in sori, where always abundant; texture thinly to thickly coriaceous; veins visible to invisible, endings not darkened; midrib raised somewhat on lower surface, concolorous with or darker than lamina. Sori subglobose to oblong, in upper part of frond, sometimes terminal, 1-12 pairs, 1.0-4.5 × 0.5-2.0 mm, usually confluent when mature; soral vein somewhat longer than sorus, shorter than basiscopic vein, neither reaching margin. Sporangia (230.0-)271.7-338.7(-400.0) microns long; indurated cells of annulus (10-) 11.6-15.6(-21). Spores (30.0-)38.8-49.6(-60.0) microns diameter.

Taxanomic notes
The New Zealand species of Grammitis along with Ctenopteris heterophylla and one Australian Grammitis (G. garrettii) one Lord Howe (G. diminuta) and one species endemic to the Moluccas and Indonesian (G. kairatuensis) have traditionally been placed in Grammitis (Parris & Given 1976; Parris 1998). However, these species (with the exception of G. diminuta, G. kairatuensis and G. stenophylla; B.S.Parris pers. comm. to P.J. de Lange January 2011) have now been transferred to a new genus, Notogrammitis Parris (Perrie & Parris 2012).
