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.

Distribution

Indigenous. New Zealand: North and South Islands (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

Features

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 X 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) microns long; indurated cells of annulus (9.0-)9.9-12.3(-14.0). Spores (20.0-)23.5-27.3(-33.0) micron 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
