 Description

Dense cushion sub-shrub to 0.06 m tall. Stems erect, densely crowded, rarely more lax and ascending, glabrous. Leaf bud indistinct, its outer leaves fully grown, separating early. Leaves sub-decussate, sub-erect to appressed; lamina thin, oblanceolate, obovate, or spathulate, rarely broadly obovate, 1.7–4.5 mm long, 0.8–2.9 mm wide, dull green to olive-green above and beneath in distal half, becoming pale green, brownish, or purplish at base; veins not evident; hairs stiff, eglandular, appressed or spreading: on surfaces absent or isolated and scattered distally; margin sparsely to densely, irregularly to regularly ciliate throughout or in distal or basal half, often with an apical tuft, sometimes a few glandular hairs as well; apex obtuse; base slightly narrowed; petiole absent. Inflorescence a solitary axillary bibracteate flower; flowers female or male on separate plants, ♂ > ♀; bracts 2, opposite, narrowly to very narrowly lanceolate to oblanceolate, rarely narrowly ovate to obovate, ± equalling and investing calyx; pedicel absent. Calyx lobes 5, obtuse to sub-acute, 1.8–3.6 mm long, equal, eglandular-ciliate, rarely also glandular-ciliate, glabrous on adaxial surface, usually sparsely hairy distally on abaxial surface. Corolla 2.1–6.5 mm diameter; tube white, 2.7–6.0 mm long, ≥ calyx, glabrous; lobes 5, white, erecto-patent to spreading, equal, obovate to broadly obovate, 1.2–3.0 mm long, obtuse; nectar guides absent. Stamen filaments white, 0.25–1.25 mm long; anthers magenta or purple. Style glabrous, 3–7 mm long. Capsules angustiseptate, emarginate, glabrous or with isolated hairs at apex, 2.5–3.5 mm long, 1.4–3.1 mm at widest point. Seeds ellipsoid, weakly flattened, smooth, brown to orange-brown, 0.6–1.0 mm long.

Morphological features to distinguish the snow hebes in Veronica (sensu lato: i.e. Chionohebe, Hebejeebie, Parahebe p.p.). Species are ordered according to similarity of their habit.

 Notes

Veronica ciliolata is classified in V. subg. Pseudoveronica sect. Hebe and informally in the “snow hebe” group (Albach & Meudt 2010). Analysis of nuclear ITS sequence data indicate the cushion snow hebes are a natural group, with V. ciliolata sister to a clade comprising V. chionohebe, V. thomsonii , and V. pulvinaris, whereas chloroplast DNA data have the relationships of these species associated with V. trifida, V. densifolia, and related species, suggesting, as is strongly indicated by morphology, that hybridisation sometimes occurs within this wider group.
