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

GINBAX

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

Gingiidium enysii var. baxteri J.W.Dawson, Gingidia enysii var. baxteri J.W.Dawson

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

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
