NVS code

The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Current conservation status

  • Conservation status of New Zealand indigenous vascular plants, 2017

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

Endemic. New Zealand: North, South and Chatham Islands. Scarce on the Chatham Islands where it is only known from Rekohu (Chatham Islands)

Habitat

Coastal to montane in closed and open forest and gumland scrub. Usually on semi-shaded mossy clay banks, in overhangs on rock, soil, clay or along stream side banks. Often in rather dry or seasonally dry, semi-shaded sites. This species appears to resent poorly drained habitats.

Features

Terrestrial tufted fern. Rhizomes short, stout, erect, bearing numerous dark brown hairs. Fronds submembranous, ± cartilaginous, dark olive-green, adaxially glossy, surfaces often covered in epiphyllous liverworts and mosses. Stipes 50-200 mm long. Rachises winged only near apices. Laminae 60-150 × deltoid, 3-pinnate. Primary and secondary pinnae overlapping, stalked; ultimate segments broad, deeply toothed, the veins forking several times in each. Sori sessile, borne in notches of lamina segments, several on each primary pinnae. Indusia tubular, mouth slightly flared, receptacle exserted.

Similar taxa

Easily recognised by the erect rhizome, deltoid, dark olive-green fronds (which often support epiphyllous bryophytes), and by the conspicuous tubular indusia bearing brown hair-like, bristly well exserted receptacles.

Flowering

N.A.

Flower colours

No flowers

Fruiting

N.A.

Propagation technique

Difficult - should not be removed from the wild

Etymology

trichomanes: From the ancient Greek name used by Theophrastus and Dioscorides, for a type of fern; refers to the slender hair projecting from each spore case

elongatum: Elongate

Where To Buy

Not commercially available.

Taxonomic Notes

Previously NZPCN had followed Ebihara et al. (2006) in recognising Abrodictyum as distinct from Trichomanes - recently Brownsey & Perrie (2016) have rejected this idea favouring a return to the past broad circumscription of Trichomanes used in New Zealand.
