Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Synonyms

Lindsaea cuneata (G. Forst.) C.Chr.; Lindsaea cuneata var. lessonii (Bory) C.Chr.; Lindsaea trichomanoides var. lessoni (Bory) Hook.f.; Lindsaea lessonii Bory in Duperrey; Schizoloma trichomanoides (Dryand.) Kuhn; Adiantum cuneatum G.Forst.; Adiantum trichomanoides (Dryand.) Poir.

Distribution

Indigenous. New Zealand: North, South, and Stewart Islands. Also Australia. Common from Te Paki south and west throughout the North Island (less common in the east);in the South Island confined to the Marlborough Sounds and west coast of the South Island.

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 Uncinia spp. (especially U. banksii, U. distans and U. filiformis).

Features

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.
