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). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

Distribution
Indigenous. New Zealand: North, South, Stewart and Chatham Islands. Also Australia
Habitat
Coastal to montane. Usually in forest, especially lowland, riparian forest.
Features
Rhizome short-creeping, 5–8 mm diameter, densely scaly and hairy; scales 4.0–9.6 × 0.5–1.0 mm, dark red-brown to red-black, bristly, persistent. Fronds crowded. Stipe 100–480(–500) mm long, densely invested in harsh, bristly, stiff red-brown scales 4.0–9.6 × 0.5–1.0 mm and shorter, glandular hairs. Lamina 3–4-pinnate, deltoid, 100–500 × 60–300 mm, dark brownish green, rugose, glabrous except on veins and midribs; these invested in black bristly scales and smaller brown hairs; rachis bearing red-brown bristly scales and hairs; primary and secondary pinnae stalked, finely dissected. Ultimate segments narrowly oblong-lanceolate, sharply toothed; margins thickened with deeply cut into narrow curved teeth. Sori medial on the veinlets, or at the fork of these; indusium pale brown.
Similar taxa
Distinguished from the other New Zealand Lastreopsis and Parapolystichum species by the harsh fronds, and distinctive stipes and rachises covered in bristly red-brown to black scales.
Flowering
Not Applicable - Spore Producing
Flower colours
No flowers
Fruiting
Not Applicable - Spore Producing
Propagation technique
Easily grown provided plants are planted in a permanently moist, shaded, well drained, humus enriched soil
Etymology
lastreopsis: Like Lastrea, a fern known to the ancient Greeks; from the greek Lastrea and opsis
hispida: Roughly hairy
TAXONOMIC NOTES
In a recent reassessment of the generic position of Lastreopsis Labiak et al. (2015) placed most of the New Zealand species of Lastreopsis within Parapolystichum. Gardner et al. (2017) completed the transfer -confirming in the process the findings of Labiak et al. (2015) that Lastreopsis hispida and L. velutina are still correctly assigned to Lastreopsis.
