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
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.

Endemic. Auckland, Campbell and Antipodes Islands
Coastal to montane. On cliffs, rock ledges, sodden areas of exposed peat and in herbfield. Often sympatric with A. latifolia Hook.f.
Stout perennial plants up to 1.2 m tall. Basal leaves ovate to oblong 0.1-0.6 x 0.06-0.15 m, 3-4-pinnate, divisions widely divergent to divaricate, and in many planes; leaflets 5-7 pairs, ovate, shortly petiolulate to sessile, coriaceous; ultimate segments linear, 10-30 x 1-15 mm, adaxially narrowly grooved, apices pungent, acicular; petioles 30-300 x 3-15 mm, abaxially broadly grooved, sheaths 25-70 x 20-35 mm, apically prolonged as a broad lobe, this free from the petiole for 1-3 mm; cauline leaf sheaths inflated; peduncles 20-100 mm long, often several at a node. Inflorescence axis 0.6-1.2 m x 0.1-0.3 m. Flowers dark pink to magenta. Staminate involucre of several linear bracts 10-25 x 1-1.5 mm; involucel of similar linear bracteoles 3.0-15.0 x 0.5-1.0 mm; rays 10-25, 10-40 mm; pedicels 20-40, 2-6 mm long. Carpellate involucre similar, , linear bracts 10.0-30.0 x 0.5-1.0 mm; involucel bracteoles linear, 3-15 x 0.5-1 mm, rays 10-25, 10-40 mm long, pedicels 10-30, 0.5 mm long; styles stout, 0.5-1 mm long, divergent, stigmas capitate, reddish. Mericarp narrowly elliptic to narrowly oblong (4.5-)5.0-7.0 mm long; apex and base obtuse; 3-5-ribbed, ribs even, equal, thin, narrowly winged, opague. Surface dull, ribs pale brown, vittae obscured
Distinguished from A. latifolia by the much more finely divided leaves and dark pink to magenta flowers.
October - March
March - May
Winged mericarps are dispersed by wind (Thorsen et al., 2009).
Easily grown from fresh seed but fickle in cultivation. Dislikes humidity, warm climates and prone to sudden collapse even when apparently flourishing.
Not Threatened. Listed because it is a narrow range endemic. In the past this species was seriously threatened by browsing animals on Campbell Island. Following their eradication it is now locally abundant there. On the Auckland Islands it is uncommon on the main island which still harbours feral pigs. Otherwise it is abundant on the outer islands and also the Antipodes Island group.
anisotome: Unequal sided
antipoda: Named after the Antipodes i.e. Australia or New Zealand which are on the opposite side of the world from Europe
