Detailed description
Epiphytic (rarely terrestrial or rupestral) fern. Rhizome erect to short-creeping; paleae pale red-brown, lanceolate to narrowly lanceolate, acute to broadly acute, 1.5–4.3 × 0.4–1.2 mm. Stipe indistinct, winged almost to base; stipe hairs whitish to pale red-brown, abundant, 0.4–1.6 mm long. Lamina (23)–46–96–(139) × (3.5)–5.0–8.8–(12) mm, linear-elliptic to oblanceolate, acute to obtuse,margins rarely somewhat crenulate; lamina hairs whitish to pale red-brown, common to abundant everywhere, 0.5–1.2 mm long in sori, usually somewhat shorter on margin (0.2–0.6 mm long); texture thinly coriaceous; veins visible or not, sometimes raised on upper or lower surface in dried material; midrib raised on lower surface, concolorous with or darker than lamina. Sori oblong, oblique, in middle part of frond, 8–22 pairs, 1.5–5.0 × 1.0–1.5 mm. Soral vein not or slightly prolonged beyond sorus; basiscopic vein approaching margin, soral vein rarely almost equalling basiscopic vein. Sporangia (150)–160.8–193.6–(240) μm long; indurated cells of annulus (9.0)–9.9–12.3–(14.0). Spores (20.0)–23.5–27.3–(33.0) μm diameter.
Similar taxa
Notogrammitis pseudociliata is most often confused with N. ciliata from which it is distinguished by its larger size, usually epiphytic habit; by the greater lamina dimension (mostly 45–95 × 5–9 mm), and whose margins are copiously covered in hairs which are shorter than those of the lamina.
Distribution
Indigenous. New Zealand: North Island, South Island (from Kaitaia south and mostly westerly). Also Australia (Tasmania).
Habitat
Coastal to montane in closed forest, Mostly epiphytic, sometimes found on moss covered rocks, shaded cliff faces or on clay banks.
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).

Other information
Etymology
notogrammitis: From the Greek noto- ‘southern’ and gramma ‘line’, referring to this new genus of southern strap ferns which were previously in Grammitis.
pseudociliata: From Greek and Latin, meaning “false eyelashes”. Refers to plant being covered in small cilia (microscopic hair-like structures).
