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.

Distribution
Endemic. Banks Peninsula
Habitat
Virtually confined to exposed outcrops of volcanic rocks and associated talus. Occasionally found in open grassland
Features
Stout tufted glaucous perennial herbs forming small circular patches 100 x 100 mm; bases clean from dead leaf remnants. Petioles 10-20 x 0.5-2.0 mm; sheaths 6-10 x 3-7 mm. Leaves once pinnate rarely 2-pinnate, subfleshy, 30-100 x 8-30 mm, distinctly glaucous to slate-blue on both surfaces; leaflets 2-10 pairs, each 3-12 x 3-10 mm, simple, pinnatifid or pinnate with one to two (or more) segments, segments overlapping, cut almost to midvein, terminal leaflets similar in size to the lateral leaflets; stomata abundant on both surfaces, leaflets sessile or with short petiolules. Inflorescences 50-170 mm long with axes 1.0-1.5 mm diameter below the first node; compound umbels 1-4 per inflorescence; in simple umbels 2-6 per compound umbel; bracts free or partly fused; flowers 5-12 per simple umbel; styles 0.75-2.00 mm long. Mericarps (excluding style) 2.5-5.0 mm long, dull light orange-yellow, orange-brown to brown, sometimes tinged purple, vittae dark brown to black-brown; narrowly ovate, ovate to narrowly ovate-oblong; apex narrowed to 2-3 ovate-triangular calyx teeth and usually recurved style remnant; surface broadly convex with 5 equal ribs.
Similar taxa
Differs from G. enysii (Kirk) J.W.Dawson var. enysii by the deeply pinnatifid to pinnate leaves whose segments are cut almost to the mid-vein. In all other respects similar. Both taxa are allopatric with var. enysii confined to calcareous rocks in the Castle Hill basin.
Flowering
October - January
Flower colours
Brown, Orange
Fruiting
November - May
Propagation technique
Easily grown from fresh seed. Does well in a well drained, sunny situation. Does not tolerate overshadowing and dislikes prolonged humidity or wet poorly draining soils. Responds well to regular applications of lime
Threats
Probably more secure than G. enysii (Kirk) J.W.Dawson as it habitats seem more free of weeds. However, because it has been regarded from sometime as merely part of the variation of G. enysii, thorough investigations of the status of known populations have not been conducted. Pending the outcome of these surveys NZPCN tentatively regard this variety as Range Restricted.
Etymology
gingidia: A Syrian carrot
enysii: Named in honour of John Davies Enys (1837-1912), a Cornish geologist, biologist and farmer, who owned Castle Hill Station in Canterbury from 1867 to 1891.
