- ≡ Parahebe spectabilis Garn.-Jones in Garnock-Jones & Lloyd, New Zealand J. Bot. 42: 223 (2004)
Low sub-shrub to 0.2 m tall. Stems trailing, decumbent to ascending, mixed eglandular- and glandular-hairy; hairs uniform. Leaf bud indistinct; leaves separating while very small, opposite-decussate, erecto-patent to spreading; lamina sub-coriaceous, broadly obovate to spathulate, 4.5–13.0 mm long, 2.5–6.0 mm wide, dull dark green to purplish above and beneath; veins not evident; surfaces sparsely to densely mixed glandular and eglandular hairy; margins mixed ciliate and glandular ciliate, crenate to lobed, rarely entire; lobes in 1–2 pairs; apex rounded or truncate; base cuneate; petiole 1–3 mm long. Inflorescence a lateral few-flowered raceme, 10–25 mm long, or a solitary bibracteate flower; flowers crowded, 2–3 or sometimes 1, all bisexual; bracts opposite, linear to spathulate, > pedicels; pedicels erecto-patent to sub-erect, 2.5–5.0 mm long, mixed glandular- and eglandular-hairy all around. Calyx lobes usually 4, sometimes a short linear 5th lobe present, sub-acute to obtuse, 5.5–9.0 mm long, equal, mixed glandular- and eglandular-hairy. Corolla 18–25 mm diameter; tube white or greenish, 6–7 mm long, = or slightly < calyx, glabrous; lobes 4, white, sub-erect to recurved, sub-equal, obovate to orbicular, 9–13 mm long, rounded; nectar guides absent. Stamen filaments white, 3–4 mm long; anthers magenta or purple. Style glabrous, 3.5–4.5 mm long. Capsules angustiseptate, emarginate or truncate, mixed glandular- and eglandular-hairy at apex, 4–5 mm long, 4–5 mm at widest point. Seeds ovoid to ellipsoid, weakly flattened, very finely papillate, straw-yellow to pale brown, 1.0–1.4 mm long.

High alpine rock crevices and mossy ledges. Recorded elevations range from 1340 to 1521 m.
A putative hybrid V. ciliolata × spectabilis has been collected once (OTA 31255).
Flowers: January; fruits: March–April (persisting longer).
Chromosome number not determined.
Veronica spectabilis is classified in V. subg. Pseudoveronica sect. Hebe and informally in the “snow hebe” group (Albach & Meudt 2010). ITS sequence data (Albach & Meudt 2010) place V. spectabilis as sister to V. trifida and V. densifolia with moderate support. Chloroplast DNA sequences also support a relationship to V. densifolia, but inferred relationships within the wider group are different (Albach & Meudt 2010), perhaps due to chloroplast exchange among species. Morphology suggests a close relationship to V. birleyi, a hypothesis that has not yet been tested with molecular data.
The seed description is based on very limited material and might not represent the range present.
