Current Conservation Status

2012 - Not Threatened

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.

Features

Rupestral (rarely terrestrial) fern. Rhizome long-creeping, rarely short-creeping, sometimes mat-forming, especially when dwarfed; paleae ovate-lanceolate, acute or apiculate, 1.5-3.0 × 4.5-0.75 mm. Stipes marked, (1-)5-20 mm long; stipe hairs usually dark red-brown, rarely paler, abundant, 0.5-3.0 mm long. Lamina (6-)20-70(-130) × (2.0-)2.8-5(-10) mm, linear oblanceolate to linear-spathulate, acute to obtuse; lamina hairs dark red-brown, rarely paler, 0.5-3.0 mm long, absent to common on lamina apart from in sori, where always abundant; texture thinly to thickly coriaceous; veins visible to invisible, endings not darkened; midrib raised somewhat on lower surface, concolorous with or darker than lamina. Sori subglobose to oblong, in upper part of frond, sometimes terminal, 1-12 pairs, 1.0-4.5 × 0.5-2.0 mm, usually confluent when mature; soral vein somewhat longer than sorus, shorter than basiscopic vein, neither reaching margin. Sporangia (230.0-)271.7-338.7(-400.0) microns long; indurated cells of annulus (10-) 11.6-15.6(-21). Spores (30.0-)38.8-49.6(-60.0) microns diameter.
