White bergmint

Killickia pilosa is a prostrate, aromatic perennial herb with slender, spreading branches up to about 75 cm (30 in) long. The internodes measure 1–5 cm (0.4–2.0 in). The leaves are ovate, with the basal leaves sometimes almost circular, measuring 7–28 mm (0.28–1.10 in) long and 6–27 mm (0.24–1.06 in) wide, though smaller on creeping stems. Leaf tips range from acute to rounded, the bases are shallowly heart-shaped to broadly wedge-shaped, and the margins are crenate with a small number of teeth. Petioles are 1–5 mm (0.04–0.20 in) long. Flowers occur singly or in pairs per bract, and only very rarely in larger, loose cymes. The peduncles are thread-like and 5–24 mm (0.20–0.94 in) long, bearing two small bracteoles in the distal half; the pedicels are 1–10 mm (0.04–0.39 in) long. The bracteoles are narrow and linear, measuring 1–2.5 mm (0.04–0.10 in). The calyx is bell-shaped, with 15 veins and a tube 1.5–4 mm (0.06–0.16 in) long. The triangular calyx teeth are 1–2 mm (0.04–0.08 in) long, straight to slightly curved outward, and expand as the fruit develops. The corolla is almost white (especially in the midlands) to violet-tinged (especially around Cathedral Peak), often creamy yellow on the lower side between two hairy ridges, and measures 9–19 mm (0.35–0.75 in) in length. The corolla tube is 5–12 mm (0.20–0.47 in) long and 3–7 mm (0.12–0.28 in) wide at the mouth. …
