Simplified description
Spreading low shrub bearing masses of narrow scaly twigs inhabiting the mountains of western Otago. Leaves scale-like, rounded, clasping stem, with a fuzzy line between the hairy-margined leaves (lens needed for both). Flowers white, in groups of 4-10 at tips of twigs.

Detailed description
Low, spreading shrub up to 0.5 x 1 m. Branches whip-like, at first erect or ascending, becoming spreading at maturity; internodes 0.5-2.2 mm; branchlets, including leaves 1.8-2.9 mm wide; fused leaf bases finely hairy; nodal joint obscure, exposed or hidden; leaves long-persistent, not readily abscising. Leaves fused, scale-like, appressed, not thickened near apex; apex obtuse, sometimes finely mucronate; margin conspicuously fine-ciliate; exposed surface (the leaf undersides) green to yellowish-green, veins not evident. Inflorescence 25-70 mm long, terminal, unbranched, bearing 4-10 flowers. Bracts opposite and decussate, fused, semi-circular, obtuse. Flowers white, sessile. Calyx 1.5-2.2 mm, 3-lobed, that is with anterior lobes fused to apex (forming one large lobe which may split longitudinally); lobes broadly oblong, obtuse or slightly emarginate. Corolla tube 1.5-1.7 x 1.2 mm, funnelform, shorter than or equaling calyx, inner portion hairy; lobes white at anthesis, broadly oblong, elliptic to obovate, obtuse, erect or recurved, longer then corolla tube. Stamen filaments 2.6-3.5 mm; anthers 1-1.2 mm, pink or purple. Ovary 0.6-0.8 mm, globose, apex didymous; style 2.5-4.2. Capsules 1.8-2.7 x 1.5-1.9 mm, pale brown, obtuse. Seeds 0.9-1.3 x 0.5-0.8 mm, weakly flattened, pale brown, obovoid or narrow and irregular, more or less smooth.
Similar taxa
Very similar to Veronica armstrongii and perhaps it might be better placed within that species, possibly at subspecies rank. The main differences are that in comparison to V. armstrongii, V. annulata has stouter branchlets, the leaves are more imbricating (overlapping), more strongly appressed, and their apices typical obtuse, and only rarely mucronate. Cytologically Veronica annulata is diploid (2n = 42) and V. armstrongii tetraploid (2n = 82). Ecologically Veronica annulata appears to be prefer well drained, rocky ground, often at the toe of avalanche debris, or rotational slumps, or in colluvial material. Veronica armstrongii is consistently found in or near permanently wet ground, usually in close association with bog pine (Halocarpus bidwillii).
Distribution
Endemic. Eastern South Island where known from Otago and Southland. Sparingly recorded from the Remarkables, Hector, Criffel Ranges and the Takitimu Mountains, also known by one old hsitoric gathering from near Kurow.
Habitat
Upper montane to subalpine. A species of open, sparsely vegetated shrubland where it is usually found at the toe of steep slopes, often in and around boulders.
Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.

Threats
Aside form Kurow (where the species has not been seen for well over 100 years) there is no evidence of any decline. Hebe annulata just seems to be a naturally, extremely uncommon, plant which in the wild is known from only a few widely scattered locations, and from very few mature individuals.

Life cycle and dispersal
Seeds are wind dispersed (Thorsen et al., 2009).
Propagation technique
Easily grown from semi-hardwood cuttings and from fresh seed. An attractive plant for a moist, sunny situation in a free draining soil. A shy flowering species that is intolerant of high humidity and wet climates.
Other information
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’.
annulata: From the Latin annulatus ‘ringed, ring-shaped’
