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) – 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.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – an interim threat classification status has not been assessed by the NZTCS panel.

Distribution
Indigenous. New Zealand: Chatham Islands, Antipodes Islands, Auckland Islands and Campbell Island/Motu Ihupuku. Also South America (Chile, Argentina), Tristan da Cuntha, and Gough Islands.
Habitat
Coastal to subalpine (in coastal forest on the Chatham Islands and Auckland Islands), extending from the coast to the subalpine areas on the Antipodes Islands, Auckland Islands and Campbell Island/Motu Ihupuku. A common epiphyte on Dracophyllum scoparium and D. cockayneanum on Campbell Island/Motu Ihupuku. Recorded from Dracrophyllum arboreum on the Chatham Islands.
Detailed description
Tufted epiphytic (rarely rupestral or terrestrial) fern usually forming colonies. Rhizome erect to short-creeping; plants often colonial, fronds rather lax; paleae light brown, lanceolate, acute or rarely obtuse, 1.9–4.0 × 0.3–0.7 mm. Stipes indistinct, winged to base; stipe hairs absent or very rare, whitish, to 1.0 mm. Lamina (22)–40–96–(120) × (2)–2.8–5.0–(6.5) mm, linear-oblanceolate, acute; lamina hairs absent or very rare, as those of stipe; texture coriaceous; veins invisible, vein endings sometimes marked by a black marking, perhaps a hydathode, on the upper surface; midrib raised on lower surface, concolorous with or slightly darker than lamina. Sori oblong, oblique, in upper ⅓–⅔ of frond, 4–21 pairs, 1.5–5.0 × 1.0–1.5 mm; soral vein ending within the sorus or extending a little beyond it, shorter than basiscopic vein, neither approaching margin very closely. Sporangia (180)–212.6–269.0–(300) μm long; indurated cells of annulus (8.0)–10.4–13.0–(15.0) μm. Spores (25.0)–29.8–38.0–(50) μm diameter.
Similar taxa
Distinguished by the combination of having a tufted, shortly creeping growth habit, fronds that < 100 mm long, are glabrous (or nearly so), and a paleae that is < 6 mm long. In Notogrammitis angustifolia subsp. angustifolia the plants are often colonial, the fronds tend to be laxly arranged and the vein ends conspicuously darkened. On the Chatham islands both subspecies occur.
Life cycle
Minute spores are wind dispersed (Thorsen et al., 2009).
Propagation technique
Difficult—should not be removed from the wild.
Etymology
notogrammitis: From the Greek noto- ‘southern’ and gramma ‘line’, referring to this new genus of southern strap ferns which were previously in Grammitis.
angustifolia: From the Latin angustus ‘narrow, constricted’ and folius ‘leaf’, meaning narrow-leaved

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) were in 2012 transferred to a new genus, Notogrammitis Parris (Perrie & Parris 2012).
