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.

NVS Species Code

GINDEC

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.

Structural Class

Dicotyledonous Herbs other than Composites

Synonyms

Aciphylla decipiens Benth. et Hook.f., Ligusticum decipiens Kirk, Angelica decipiens Hook.f.; Ligusticum petraeum Cheeseman, Anisotome petraea (Cheeseman) Cheeseman, Gingidum decipiens (Hook.f.) J.W.Dawson

Distribution

Endemic. South Island, mainly westerly from Nelson to Fiordland

Habitat

Subalpine to alpine herbfield (up to 1600 m a.s.l.). Rupestral within rock crevices, ledges and within talus slopes and debris slides. Usually found on limestone, marble or granite, or base-rich facies of greywacke.

Features

Stout yellow-green to dark green or glaucescent perennial from compact tufts up to 200 mm wide. Bases surrounded by persistent dead leaf remnants. Plants not rhizomatous. Petioles 10-80 x 0.75-1.5 mm, sheaths 6-20 x 3-7 mm. Leaves once-pinnate, rarely 2-pinnate, sub-fleshy, 40-180 x 5-40 mm yellow-green, dark green to glaucescent; leaflets 5-10 pairs, these 4-24 x 3-16 mm, sessile or shortly petioluled with petiolules up to 5 mm long; mostly pinnatifid or pinnate, rare simple; if pinnatifid or pinnate with two pairs of segments; segments not overlapping, stomata equally abundant on both surfaces. Inflorescences 80-200 mm long with axes 0.75-2.0 mm diameter; compound with umbels 1-3 per inflorescence; simple umbels 5-10 per compound umbel; bracts free; flowers 8-15 per simple umbel; styles 1.5-3.0 mm long. Mericarps (excluding style) 3.2-6.0 mm long, dull or glossy, finely bullate on wings, dark yellow, brown or tinged purple, vittae dark brown, dark red-brown or dark purple-brown; ovate-oblong or ovate; apex rounded or narrowed to 2-3 lanceolate to ovate-triangular calyx teeth and thin twisted style remnant; surface broadly convex with 5 equal ribs, the 2 commissural broadly and evenly winged, or with wings broadening toward base.

Similar Taxa

Distinguished from all other New Zealand species of Gingidia by the usually green to yellow green rather than glaucous leaflets which are < 15 mm long, in 5-10 pairs, mostly pinnatifid to pinnate (rarely simple), with the lower leaflets sessile or on short petiolules up to 5 mm long, usually truncate or obtuse at base. Simple leaflets usually bear 7 or more teeth, while pinnatifid leafllets have 5 or less teeth per proximal segment. More likely to be confused with Anisotome Hook.f. from which it is best distinguished by leaflet teeth which are not produced into hairs or bristles, and the obvious aniseed smell of the leaves when crushed.

Flowering

October - April

Flower Colours

Brown,Yellow

Fruiting

November - June

Propagation Technique

Easily grown from fresh seed. An excellent and attractive rockery plant. Ideal in a pot. Prefers free draining moist soils. Benefits from regular applications of lime.
