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 to Tasmania and New Zealand. (Confined to old rock lithologies in the South Island, where it has been sparingly collected from Kahurangi National Park (Iron Hills, Mt Arthur), Fiordland, Waitutu Forest, Eyre and Umbrella Mountains.

Habitat

A "old-rock" species of granite, marble, greywacke and schist outcrops or growing in soil lodged amongst boulders derived from these substrates.

Features

Fern, with strap-like fronds. Rhizome long-creeping. Fronds 12-37 × 3-5 mm, leathery (coriaceous). Hairs pale to red-brown, simple 0.2-1.3 mm long; confined to frond undersides, where associated with sori, sometimes on the frond margin, midrib, or sparsely covering frond undersides. Veins no evident in natural or artificial light. Sori (spore bearing structures) rounded to elliptic, 1-4(-7) pairs restricted to distal one-sixth to two- thirds of frond.

Similar Taxa

Allied to Notogrammitis givenii, but differing from that species by the presence of hairs amongst the sori.

Flowering

Not applicable - spore producing

Fruiting

Not applicable - spore producing

Propagation Technique

All Notogrammitis species are believed to be difficult (if not impossible) to grow. So while no specific information on the cultivation of N. gunnii is known, there is no reason why it should be any different.

Threats

Notogrammitis gunnii was described by Parris (1998 - as Grammitis gunnii) from Tasmanian specimens. In that account it was noted that it also occurs in New Zealand. Within its New Zealand range the species is reported from North-West Nelson (Kahurangi National Park) and Fiordland. Virtually nothing is known about this species, and surveys for it to date have been unsuccessful.
