Description

Veronica brownii is a perennial herb with slender arching decumbent branches about 50 cm (20 in) long with pale lilac flowers at the end of the stems. The stems have lateral bands of fine, stiff hairs 0.1–0.2 mm (0.0039–0.0079 in) long and curved downward. The stems occasionally arise from a leaf or branch node. The leaves may be broad to narrow egg-shaped or more or less triangular, usually 0.8–2 centimetres (0.31–0.79 in) long and 2.5–15 mm (0.098–0.591 in) wide, sharply pointed or tapering gradually to a point. The leaf stalk is 1.5–5 mm (0.059–0.197 in) long and the leaf margin has 2-5 pairs of deep sharp teeth. The inflorescence is a slender raceme about 3.5 cm (1.4 in) long with 3-15 flowers per stem on a peduncle 1.5–4.5 cm (0.59–1.77 in) long. The flower bracts are 2–6 mm (0.079–0.236 in) long, the pedicel 8–15 mm (0.31–0.59 in) long. The flower petals are 3.5–4 mm (0.14–0.16 in) long and pale lilac. Flowers from spring to summer. The seed capsules are egg-shaped 2–4 mm (0.079–0.157 in) long and 3.5–5.0 mm (0.14–0.20 in) wide, smooth or sparsely covered in fine hairs less than 0.1 mm (0.0039 in) long.[2]
