Detailed description
Terrestrial, tufted fern. Rhizome short- to long-creeping, to 1.5 mm diameter; scales narrowly triangular, reddish brown. Fronds monomorphic, erect and stiff. Stipes clustered or more widely spaced, shorter to longer than lamina, glossy, reddish brown to dark brown. Lamina 100–280 × 30–68 mm, 1–2-pinnate-pinnatifid, lanceolate to triangular-oblong,herbaceous. Pinnae oblong-deltoid or oblong-lanceolate, variously dissected, 4–10 mm long; pinnules flabellate-spathulate, asymmetric, often erose. Upper pinnae and pinnules gradually reduced and confluent. Veins free, simple to 3× forked. Sori mostly on 1–4 vein endings; indusium 0.3–0.5 mm wide, subentire. Spores trilete. (Description from Kramer & McCarthy (1998)).
Similar taxa
Easily distinguished from the two other New Zealand species of Lindsaea by the terrestrial habit (not rheophytic like L. viridis), by the broader, bipinnate fronds with round ended ultimate segments.
Distribution
Indigenous. New Zealand: North Island (common from Te Paki south and west throughout, less common in the east), South Island (confined to the Marlborough Sounds and West Coast), Stewart Island/Rakiura. Also Australia.
Habitat
Coastal to montane. Usually in closed forest (sometimes in scrub) often growing in relatively open sites on the forest floor, in leaf litter or amongst Carex spp. (especially C. banksiana, C. subviridis and C. lectissima).
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.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.
