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
The threat classification 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) – more information about this can be found on the NZTCS website 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. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Distribution
Endemic. South Island, north-west Nelson (Gouland Downs), Otago and northern Southland.
Habitat
Montane to alpine (up to 1300 m a.s.l.). usually on base-rich schist and greywacke facies, and in the Nelson are an limestone and peat overlying limestone. Favouring open herbfield, fell field and stable talus slopes
Features
Stout tufted distinctly to weakly 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, membranous, 30-100 x 8-30 mm, upper surface distinctly to weakly glaucous under surface green; leaflets sessile, 2-10 pairs, each 3-12 x 3-10 mm, simple, or with 1-2 incisions, terminal leaflets similar in size to the lateral leaflets; stomata abundant on both surfaces. 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 and G. enysii var. peninsulare J.W.Dawson by the sessile rather than sessile to petiolulate leaflets which are glaucous to weakly so above, and green below, and are simple rather than deeply cut, occasionally bearing one or two incisions, rather than cut by one-third or more to the mid-vein. Gingidia baxterae is allopatric from both G. enysii varieties.
Flowering
October - March
Flower colours
Brown, Orange
Fruiting
November - June
Life cycle
Winged mericarps are dispersed by wind (Thorsen et al., 2009).
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
Etymology
gingidia: A Syrian carrot
Where To Buy
Not commercially available
