 Description

Compact or straggling shrub to 0.5 m or rarely to 1.0 m tall. Stems ascending to stiffly erect, sparingly branched, eglandular-pubescent, hairs bifarious. Leaf bud distinct, its leaves appressed until fully grown; sinus broad, shield-shaped. Leaves opposite-decussate, erecto-patent, rarely sub-erect or spreading; lamina coriaceous, rigid, broadly oblong or elliptic to sub-orbicular, 3–9 mm long, 2.2–8.0 mm wide, glossy dark green above and beneath; midrib evident and characteristically flattened in a patch just short of the apex; surfaces glabrous; margin glabrous or minutely ciliolate, entire; apex obtuse to bluntly apiculate; base truncate to cordate; petiole 0.5–3.0 mm long. Inflorescence a lateral spike, 7–20 mm long; flowers crowded, 2–12, all bisexual; bracts elliptic to deltoid, > pedicels but not overtopping calyx; pedicels erect, 0–0.5 mm long, glabrous or with a few scattered eglandular hairs. Calyx lobes 4, the anterior pair fused ⅔-way to apex or more, obtuse, 3–4 mm long, sub-equal, minutely eglandular-ciliolate. Corolla 10–14 mm diameter; tube white, 3.7–5.0 mm long, > calyx, glabrous or eglandular-hairy inside; lobes 4, white, spreading to recurved, sub-equal, narrowly elliptic to elliptic, 5.0–6.5 mm long, obtuse, rounded, or sometimes the posterior lobe emarginate; nectar guides absent. Stamen filaments white, 3.7–5.5 mm long; anthers magenta. Style glabrous, 3.8–8.0 mm long. Capsules latiseptate, obtuse, glabrous, 4.0–5.5 mm long, 2.5–3.5 mm at widest point. Seeds ellipsoid or broadly ellipsoid, flattened, smooth, pale brown, 1.1–1.8 mm long.

Indigenous (Endemic)
 Phenology

Flowers: November–January (sometimes to March); fruits: January–May (sometimes persisting to November).

 Cytology

 Notes

Veronica pauciramosa is classified in V. subg. Pseudoveronica sect. Hebe and the informal group “Buxifoliatae” (Albach & Meudt 2010; Bayly & Kellow 2006). V. pauciramosa consistently emerges as sister species to V. odora in nuclear ITS trees (e.g., Wagstaff et al. 2002). This sister species pair is sister to a cluster of V. epacridea and V. kellowiae (Wagstaff et al. 2002), and also V. haastii and V. macrocalyx (E.M. Low, unpublished), which all have similar inflorescences.
