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 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) – 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.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – an interim threat classification status has not been assessed by the NZTCS panel.

Lamina lanceolate, oblanceolate, ovate, obovate, oblong, elliptic, orbicular or rhomboid, 3.0-14.0 × 2.5-10.0 mm, upper surface dull green, bronze green or dark green, under surface pale green, dull. Leaf hairs sparse, numerous or absent. Apex subacute, obtuse or rounded. Base cuneate. Margin glabrous, ciliate, glandular-ciliate or pubescent, bluntly crenate to serrate. Marginal teeth or lobes in 1-4 pairs. Petiole 1-3 mm long. Inflorescence racemose, unbranched, 3-15-flowered. Peduncle 15-60 mm long, eglandular-pubescent, glandular-pubescent or mixed. Rachis 10-70 mm long, eglandular-pubescent, glandular-pubescent or mixed. Bracts alternate, obtuse to acute, eglandular-hairy above or ciliate, lanceolate to elliptic or narrowly deltoid. Bract margins entire. Pedicels erecto-patent at anthesis, straight or incurved at fruiting, 3-18 mm long, eglandular-pubescent to glandular-pubescent.

Etymology
veronica: Named after Saint Veronica, who gave Jesus her veil to wipe his brow as he carried the cross through Jerusalem, perhaps because the common name of this plant is ‘speedwell’. The name Veronica is often believed to derive from the Latin vera ‘truth’ and iconica ‘image’, but it is actually derived from the Macedonian name Berenice which means ‘bearer of victory’.
hookeriana: Named after Sir Joseph Dalton Hooker (born 1817) - a world famous botanist who travelled on the Antarctic expedition of 1839 under the command of Sir James Ross and wrote “Handbook of New Zealand Flora” published in 1864-67 describing many specimens sent to Kew by collectors. He died in 1911 and has a memorial stone at Westminster Abbey London.
