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.

Features
Low subshrub, 50-150 mm tall. Old stems brown. Branches decumbent to ascending. Branchlets brown or red-brown or purplish. Vegetative internodes 1-8 mm long. Stem pubescence absent or bifarious, eglandular pubescent. Leaves decussate, erecto-patent to recurved. Lamina linear to oblong (narrowly), 4-15 × 1-3 mm. Upper surface of leaves green, glossy. Under surface of leaves pale green, dull. Leaf hairs sparse to scattered, along margins (especially at base), eglandular. Apex rounded or truncate. Base cuneate. Margin ciliate (especially at base), entire. Petiole 1-3 mm long. Inflorescence racemose, unbranched, 10-40 mm at fruiting, with 2-6 flowers. Indumentum of peduncle, rachis, and pedicels absent. Peduncle 3-20 mm, glabrous. Rachis 0-15 mm long, glabrous. Bracts alternate (basal pair sometimes subopposite), obtuse, glabrous (rarely a few hairs on margin at base), linear to elliptic (narrowly). Bract margins entire. Pedicels erecto-patent at anthesis to suberect at anthesis, incurved at fruiting, 4-15 mm long, glabrous. Flowers: Calyx 4-lobed, 3-9 mm long. Calyx lobes lanceolate to deltoid or elliptic or obovate, subacute to obtuse. Calyx hairs absent (calyx glabrous). Calyx lobe margins entire. Corolla white at anthesis. Nectar guides pink, obscure or absent, confined to posterior corolla lobe if present. Colour ring pink or absent. Corolla throat same colour as lobes. Corolla 5-10 mm diameter.

Propagation technique
Easily grown from cuttings, rooted pieces and fresh seed. Best in an alpine house, or rock garden. Dislikes humidity and drought intolerant.
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’.
