Matting bergmint

Killickia compacta is a perennial herb with a strong, woody rootstock. Above-ground shoots are prostrate, mat-forming, and densely branched, reaching up to about 40 cm (16 in) in length. Shoots may root at the nodes and can also spread by fragmentation, forming clonal patches. Internodes are typically 5–15 mm (0.20–0.59 in) long, occasionally up to 2 cm (0.8 in). The leaves are broadly ovate to almost circular, measuring 3–11 mm (0.12–0.43 in) long and 2–10 mm (0.08–0.39 in) wide, with rounded bases and tips and shallowly crenate margins. The petioles are 2–4 mm (0.08–0.16 in) long. Flowers are solitary, with more than one flower per cyme recorded only rarely. The peduncles are very short, usually 0.1–1.5 mm (0.004–0.059 in) and always under 3 mm (0.12 in). The cyme axis bears two small bracteoles, typically in the proximal half. Flower stalks (pedicels) are 1–2.5 mm (0.04–0.10 in) long. The bracteoles are narrow, lance-shaped, about 1.5 mm (0.06 in) long, and keeled. The calyx is bell-shaped, with 15 veins and a tube just under 2 mm (0.08 in) long. The triangular to lance-shaped calyx teeth are about 2 mm (0.08 in) long and curve outward, leaving the upper part of the corolla tube exposed. The corolla is cobalt violet, 3–5 mm (0.12–0.20 in) long, hairy on the outside and largely smooth inside. …
