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.

Habitat

Coastal to montane. On cliffs, rock ledges, sodden areas of exposed peat and in herbfield. Often sympatric with A. latifolia Hook.f.

Features

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

Similar Taxa

Distinguished from A. latifolia by the much more finely divided leaves and dark pink to magenta flowers.

Flowering

October - March

Flower Colours

Red / Pink,Violet / Purple

Fruiting

March - May

Propagation Technique

Easily grown from fresh seed but fickle in cultivation. Dislikes humidity, warm climates and prone to sudden collapse even when apparently flourishing.

Threats

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.

Life Cycle and Dispersal
