Detailed description
Tufted epiphytic (rarely rupestral or terrestrial) usually solitary fern. Rhizome erect to short-creeping; plant usually solitary, fronds erect; paleae light brown, lanceolate to narrowly lanceolate, acute to broadly acute, 1.2–3.7 × 0.25–0.75 mm. Stipe ± indistinct, winged to base; stipe hairs absent or very rare, whitish, to 1.0 mm long. Lamina (16)–33–81–(136) × (2)– 2.4–4.2–(5) mm linear-oblanceolate, acute to broadly acute; lamina hairs absent or very rare, similar to those of stipe; texture thinly coriaceous to coriaceous; veins visible to invisible, endings not darkened; midrib slightly raised below, darker than lamina. Sori subglobose to oblong, oblique or nearly parallel to midrib, in upper half to two-thirds of frond but not usually in apex, 2–19 pairs, 1.5–4.0 × 1.0–2.0 mm, sometimes ± confluent and covering most of frond under surface when mature; soral vein prolonged or not beyond sorus but not as long as basiscopic vein, neither reaching the margin. Sporangia (200)–226.4–299.0–(370) μm long; indurated cells of annulus (10)–10.4–12.4–(15). Spores (25)–34.3–47.5–(58) 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 N. angustifolia subsp. nothofageti the plants are often solitary (never found in colonial masses), the fronds tend to be mostly erect and the vein ends are not obviously darkened. Small specimens of Notogrammitis angustifolia subsp. nothofageti can be confused with N. crassior, which in New Zealand is a mostly rupestral species that has a widely creeping rhizome, and mat-forming growth habit, and the scales of this species are usually shorter and broader than those of N. angusitfolia subsp. nothofageti (see comments by Parris 1998).
Distribution
Indigenous. New Zealand: North Island, Great Barrier Island (Aotea Island), South Island, Chatham Islands. Also Australia (Victoria and Tasmania).
Habitat
Coastal to subalpine. Strictly montane to subalpine in the North Island extending to the coast in Fiordland, and common in coastal forest on Chatham Island (Rēkohu). Usually epiphytic in beech (Nothofaceae spp.) forest, and in the northern part of its range in cloud forest often on tawheowheo (Quintinia serrata) or kamahi (Pterophylla racemosa).
Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.

Taxonomic 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 been transferred to a new genus, Notogrammitis Parris (Perrie & Parris 2012)

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
