ascending, usually with 4–10 nodes, 5–45(–60) cm, proximally eglandular- or glandular-hairy, sometimes glabrous, distally eglandular- and, usually, glandular-hairy. |
Leaves | in 3–6 pairs per stem; blade oblong to broadly ovate, (2–)5–14(–35) × (2–)3–10(–18) mm, 2.5 times as long as wide, base truncate, margins crenate-serrate, apex obtuse to rounded, surfaces sparsely eglandular-hairy, rarely also glandular-hairy. |
blade ovate-oblong to narrowly oblong-lanceolate, (30–)40–70(–80) × 5–20 mm, base long-cuneate, margins shallowly crenate to shallowly serrate to subentire, apex obtuse to rounded, surfaces densely glandular- or eglandular-hairy, rarely glabrate. |
Racemes | 1(–3), terminal, 20–150 mm, (5–)15–40(–60)-flowered, axis densely eglandular- and glandular-hairy; bracts linear-oblong, (3.5–)4–6(–10) mm. |
1(–7), terminal, sometimes with lateral ones, (50–)70–130(–170) mm, (50–)100–300-flowered, axis eglandular- and glandular-hairy; bracts oblong to lanceolate, 3–5 mm. |
Pedicels | erect, 0–4 mm, shorter than subtending bract, densely eglandular- and glandular-hairy. |
suberect to patent, 0.5–1(–2) mm, shorter than subtending bract, eglandular- and glandular-hairy. |
Flowers | calyx lobes (2–)3.5–5(–6) mm, 0.8–2 mm wide, apex acute, glandular-hairy; corolla sky blue to intense blue, 2–4 mm diam.; stamens 0.3–0.5 mm; style (0.2–)0.4–0.6(–1) mm. |
calyx lobes 2–3 mm, ciliate, apex obtuse, glandular-hairy, rarely eglandular-hairy; corolla blue, campanulate, longer than wide, 5–6 mm diam., lobes 3–4.5 × 1.5–2 mm; stamens 5 mm; style 8 mm. |
Capsules | compressed in cross section, obcordiform, 2–4 × 2.5–5 mm, apex markedly emarginate, glandular-ciliate, otherwise glabrous. |
± compressed in cross section, broadly ovoid, 2–3 × 2–3 mm, apex obtuse, densely glandular-puberulent. |
Seeds | 10–30, yellowish, ovoid, flat, 0.7–1.7 × 0.4–1 mm, 0.2–0.4 mm thick, rugose. |
3–40, light brown, ellipsoid, flat, 0.6–1.2 × 0.5–0.8 mm, 0.2–0.4 mm thick, smooth. |

Discussion | Veronica spicata is widely distributed in horticulture and a multitude of cultivars is available. Some specimens may also be derived from a related species, V. barrelieri Schott ex Roemer & Schultes, differentiated from V. spicata by glabrous calyx lobes, and in its typical variety, by eglandular pubescence. Another closely related species, V. incana Linnaeus, has a dense white woolly indumentum and is native to northern Asia and eastern Europe; it has not escaped from cultivation in the flora area.
